The March birthstone is the Aquamarine and the flower is the Jonquil.
AQUAMARINE, the blue variety of beryl.
VARIETY INFORMATION:
Aquamarine is the blue, or perhaps more correctly, blue-green or aqua variety of the mineral beryl. Other gemstone color varieties that belong to beryl include emerald, morganite, and heliodor. Other colors of beryl are simply refered to by their color, such as red beryl.
Aquamarine is colored by trace amounts of iron that find their way into the crystal structure. Most gem aquamarines have been heat treated to produce the popular blue-green colors from less desirable yellow or pale stones. The leading producer of aquamarines is the country of Brazil, which has many mines. Pakistan, as well as many U.S. localities, produce wonderful specimens as well.

The January meeting had 17 members, three guests and two pebble pups. The guests were Paul Polacek, the husband of our speaker, Szilvia Beylik and Mark Kaufmann. The two pebble pups were Sara Beylik and Mishell Beylik. We thank them for joining us and hope to see all of them again. Many members were off cruising the Quartzsite scene; hopefully we will see the fruits of their efforts at our February meeting! The usual fun door prizes were awarded (one to me-thank you!). Sharlyne Holloway and Shirley Layton furnished the refreshments with Sharlyne bringing her much loved "Dump Cake" which was enjoyed by all. Hope to see you all at the February meeting on the 23rd.

Friday, January 14, Jim Brace-Thompson gave a slideshow presentation and fossil exhibit on "Fossils of So-Cal: Collecting in Ventura and Santa Barbara Counties" to the Carmel Valley Gem & Mineral Society and the Pacific Grove Museum of Natural History. He then quickly drove south from Monterey to give the same presentation to the Woodland Hills Rock Chippers in Canoga Park the following day, Saturday, January 15.

For every bone that becomes a fossil, millions do not. It takes many thousands of years and very special conditions for a fossil to form. Fossils are the remains of ancient life. Fossils can be found poking out of the earth in the Badlands of South Dakota. To become fossils, bones are first buried. Usually, this happens when an animal dies by a river, stream, or ocean. In such a place, water often washes sand, mud and other fine-grained materials over the body. The soft tissue decays. The bones begin the slow process of fossilization. Over thousands of years, minerals seep into the bones, minerals fill tiny pores. As these minerals build up, the bones become heavier and stronger, but they keep their original shapes. Fossilization gradually continues until the bones have been completely replaced by minerals. Then the bones have become petrified - turned into stone.

If you think you have a rock that might be a meteorite, answer these simple questions:
1) Is the object solid, not porous?
2) Is the object of irregular shape?
3) Is the object heavy for its size?
4) Is the object black or brown on the outside?
5) Does the object show metallic iron on ground surface?
6) Is the object different from the county rocks?
If you answered "yes" to all these questions, the object is most surely a meteorite, in a few cases, some of the answers can be "no" and the object may still be a meteorite. If most of the answers are "no", the object is probably not a meteorite. Things mistaken for meteorites:
Earthy nodules of iron compound, especially hematite.
Artificial slag or cinders sometimes containing iron. Slag or cinders will generally be very porous or spongy, meteorites never are.
Pieces of old rusted iron tools are sometimes mistaken for meteorites.
Rocks showing well-shaped crystals are not likely to be meteorites.
Volcanic rocks are often mistaken for meteorites.

Table of Contents.
This is a type of rock that forms in buckets, milk crates, boxes and other containers in the backyards and garages of long-time rock hounds. Its properties vary widely; any color, texture or hardness may be found in these deposits. Often the best material is found in small pieces at the bottom of the container; great patience is needed to sift through a typical deposit. These deposits are typically pretty filthy, though the stones are easily removed and cleaned. Beware of spiders and other vermin, especially in larger deposits and in hotter climates. On the other hand, the material is quite often preslabbed, and the slabs will occasionally already have cabochon outlines marked on them. How can you tell if a piece of rock is bucketite? If you can't tell what it is and someone asks you, just tell them it's bucketite. If you got it out of a bucket even if you can't identify it, it's still pure bucketite. For more information or to see some bucketite, contact a long time rockhound. (Also known as "backyardite".)

QUIRKY QUARTZSITE:
January 2005.
Quartzsite has a huge selection of dealers in rocks, minerals, gems and jewelry. That's why so many of us make the trek to this small town in the desert in January. Small it is, ordinary it is not!
Quartzsite claims over 2,000 permanent residents. I doubt if you will find more than 100 actual houses in town. Most of the dwellings are trailers or mobile homes. In the winter, though, the town is surrounded with thousands of RVs. Maybe some of you were out there.
There's a frontier feel to the town, especially at the saloon/restaurant on the southeast corner of Main St. and Hwy. 95. The saloon opens at 7 a.m. One morning at 7:30 we went in to use their bathroom (among the few easily accessible flush toilets). The bar was already full of drinkers. Get your quick calories at the restaurant. They have great hamburgers, chicken fried steak sandwiches and onion rings!
The Quartzite Bakery was a pleasant surprise. It's at least 30 miles to the nearest fresh baked goods. The bakery doesn't look like much, but it's a jewel. We ate their wonderful muffins and French bread. The employees who waited on us were all friendly senior citizens, as are many of the workers in other permanent businesses in town.
Have you been to the bookstore? If so, you probably encountered the (almost) nude proprietor. He has a great tan, too. We recommend his illustrated map of the town! You'll need it to find the shows and to avoid the big city style traffic jam that is common on Main Street. Drive an extra half a mile to save half an hour. During the show season it's best to drive, park and walk around.
The shows that bring all of the visitors are overwhelming. Thousands of people are looking at hundreds of booths. You could spend weeks looking and still not see everything. We concentrated on three shows: Desert Gardens, Rice Ranch and the Powwow.
Desert Gardens opened with a rain storm this year. On our first visit most of the dealers were not set up for business. When we returned the weather had cleared. There was an incredible variety of rocks and wood, both rough and polished. You could find almost any rock you were looking for. The Australian dealers' displays were a highlight. They sold more varieties and higher quality rocks and minerals than last year.
Tyson Wells has the most venders and the most parking of the sites. The first day we barely found a parking place way out under the Freeway Bridge. There were so many booths that, after three hours of shopping, we still had three rows to go. We looked at a lot of jewelry and some good rough rocks, wood, fossils, slabs and cabs. There's a lot more other stuff. The guys headed for the gadgets and tools. The women headed for the kitchen gadgets and clothing. My big buys were California strawberries and asparagus. Good fresh produce is a rarity in this country so far from a supermarket. One of the best selling items was a tripod seat that folded up into a walking cane. You could sure use one at Tyson Wells!
The Powwow (put on by the Quartzsite Roadrunners) was a bit of a disappointment this year. Because of the rain and mud the crowd was small. Many of the venders packed up and left Sunday morning; the one really sunny day of the show. It was disappointing that many venders left early and that there was not much rock equipment to look at this year. There was, however, some fine jewelry being offered. The display cases in the QIA building were excellent!
Because we spent over a month in the area, Ron and I joined the Quartzsite Roadrunners Gem & Mineral Club. The shop is excellent; they even have warm water on the grinding wheels. We trimmed, cabbed and polished some purple agate from our Burro Creek fieldtrip. Bring or buy your slabs, though. They charge 20 cents an inch to slab rocks. Ron used the slab saw at the Hope RV park where we stayed.
Let's hope for better weather next year!

BURRO CREEK FIELDTRIP:
January 14-17, 2005.
Welcome to the Wild West! There's nothing around Burro Creek except for the BLM campground and Nothing, a dilapidated gas station and rock shop straight from the 1930's. The Burro Creek campground is a delight. Located on the side of a canyon cut by the creek, it provides gorgeous sunsets and striking views of the creek and the huge bridge that allows Hwy. 93 to cross it. Once in a while you might even spot one of the wild burros for whom the creek was named.
Nothing isn't much, but the road just south of the gas station is the turn-off to go to the rockhounding sites. There are roads every which way, so directions and a watchful eye are essential to getting in to (and back from) the sites. Some of the roads are rough, rocky, steep and narrow. A high clearance vehicle is recommended. This year the rain that pummeled Ventura County also hit Arizona. Although it didn't rain while we were there, we hit a number of muddy spots where we all slipped and slid a bit. We had sweaty palms!
During the four times we have hunted rocks at Burro Creek, Ron and I have visited five different sites in the area. Materials we have collected include: the famous Burro Creek purple agate, braciated pumpkin jasper, pastelite, blue agate, and multi-colored agate (blue, white, reds, oranges, and tans). Needless to say, you won't have time to do justice to all of these sites on a 3-day trip.
This year we joined the Ye Old Timers Mineral Club trip, led by Dick and Betty Pankey. We met the Old Timers at the rock show at the Avi Casino near Laughlin. No sooner had we unhooked our travel trailer from the truck, the wind changed from a breeze to a gale. The trailer was rocking and sand was seeping in all the cracks, but we didn't blow over. A number of the dealers were not so fortunate. At least three of them had their tents blown over and the poles bent out of shape. Fortunately, the second day at the Avi brought calmer weather and most of the venders had their booths open. That night we had one of the Old Timers' famous potluck dinners. We all ate very well!
The next morning we all hooked up the trailers and headed for Burro Creek campground. Fortunately, the way things have been going this winter, we had great weather.
Friday was exploration day. We all drove out to the "purple" and "pumpkin" sites to see how the roads were and how things looked. We were supposed to get back to camp early, but one of the men started exploring and got lost. He finally turned up a few miles down the creek. While we were out looking for him, Dick Pankey, the leader of the Ye Old Timers, found a 50-pound boulder of the purple agate! This was a good omen. The rains had uncovered some nice smaller specimens. Last year the rocks were buried deep in the tailing piles from the area's mining days. When we returned to camp Ron took off again to explore the north route to the Burro Creek pastelite and multi-colored agate sites. He collected a few pieces of beautiful multi-colored agate.
Saturday was devoted to the purple agate site. About a half-mile of the road to the site had been washed out by the recent rains, so we hiked in. Most of us scoured the creek for pieces of the purple. This year Ron decided to do some hard-rock mining. He started with about a 3-inch triangle visible and ended up (after two days of hard work) with a 30-pound solid purple boulder. When we got back, we got ready for our second potluck dinner. This one was even better than the first one!
Sunday most of the group went to the pumpkin jasper site. Greg and Valerie Davis from VGMS joined us at the purple agate site, where Ron was still beating out his 30-pounder. They joined me in hunting through the recently uncovered tailing piles. All three of us found lots of small pieces and some pretty decent sized hunks as well. We also got a good workout carrying our booty up the hill to the cars.
Monday the Old Timers headed for their camping site north of Quartzsite. Ron and I headed back to our home-away-from-home at Ramblin' Roads RV Park in Hope, AZ. We trimmed and made cabs from some of our small pieces. Two of the three cabs polished up beautifully!
We plan to go back to Burro Creek again next year. I hope some of you with a little time to spend will join us!
Jean Wise.

Great Website for rockhounding in the Barstow area-http://www.ca.blm.gov/barstow/rock.html.
This is from the AFMS Newsletter - December 2004-January 2005 and was contributed by Bob Cranston. It is an excellent summary of collecting rules and some descriptions of local collecting sites. It's from the Barstow BLM office.
Table of Contents.
The following "Rockhounding" has been taken from a BLM Internet article. This is from the above website.
Rockhounding.
California's geological forces have created one of the widest varieties of rocks and minerals found in any state. This rock and mineral wealth has long been recognized by rockhounds even before the gold rush days. Early rockhounds were prospectors looking for valuable minerals and gemstones for commercial purposes. Eventually, however, more people were drawn to rockhounding for recreational purposes, mainly for the beauty that rocks and minerals provide.
By the 1930s, interest in rockhounding increased significantly and it was during this period that rockhounding groups were formed and collecting areas in the desert were publicized. With increased popularity of rockhounding, some rockhounds regarded certain areas as their own and feared that other collectors would deplete their rocks and minerals. This led to substantial amounts of material being removed and an increase in mining claims. By the 1960s the government saw a need to regulate the collection of rocks and minerals on public lands. Visitors to the Mojave Desert often ask where they can rockhound. Perhaps the best source of information is rock, gem, and mineral groups found in communities throughout southern California. Libraries, bookstores, and "gem and mineral shows" are also very good sources of published information. Although any hill, mountain, or wash can provide some wonderful rock and mineral discoveries, the following listed areas are some of the well-known sites visited by rockhounds in which good samples can still be found.
Many rockhounding sites require hiking or driving to remote areas on sandy or rocky roads where there is a possibility of getting stuck. It is always a good idea to travel in a group and to bring plenty of drinking water with you when traveling in the desert. If you must travel alone, be sure to let someone know of your plans. Remember to stay on designated open roads. Cross country travel is illegal, as is driving in designated Wilderness Areas.
Rules and Regulations:
Part 8365 of Title 43 CFR (Code of Federal Regulations) provides for the collecting of "reasonable quantities" of rocks, minerals, semiprecious gemstones, and invertebrate and plant fossils of non-scientific importance, for personal use. With respect to rockhound material, the Field Office considers a "reasonable quantity" to be not more than can be carried in a daypack.
Regulations do not allow collecting on "developed recreation sites and areas", or where otherwise prohibited or posted. Care should be exercised not to collect minerals on mining claims. Most claimants will allow rockhounding if the individual interested in rock collecting first asks permission. Remember, it is your responsibility to determine if an area is open to collection or if you are on private land.
More specific rules affecting rockhounding can be found on the Internet, at http://www.ca.blm.gov/barstow/rock.html.

On December 30, 2004 Susan Itlston, a US District Court Judge, signed an order restricting OHV use in desert washes which had been open as a result of careful planning. Based on litigation filed by the Center for Biological Diversity, et al, the judge ruled that the Biological Opinion issued by the US Fish & Wildlife Service was inadequate. She determined that off-road vehicle travel down some desert washes might harm desert tortoise habitat or disturb a tortoise.
Having served on the various planning commissions, committees and groups for more than 30 years, there is no question that all safeguards possible have been put in place to assure protection for the tortoise while recognizing the needs of the public. This order ignores the needs of the public. What does this decision mean to CFMS and its members? Primarily, it may deny access to some of our favorite collecting areas.
One area in particular is the Mauser Geode Bed Area. Our Memorandum of Understanding with the Bureau of Land Management is still in place. We can access the geode beds down the existing designated routes of travel. If the designated route travels down a desert wash for a short distance, the route will remain open. If you are traveling down a designated route and turn off the route to travel down a wash, you may be in violation. The maximum fine could be $1000 and a maximum jail time of 12 months.
Please remember that our agreement requires that one side of any hole we dig must be tapered to a 30 degree angle to allow any desert tortoise that might fall into a hole to walk out of the hole. This was to keep from having to refill the hole every time we dug one.
Another issue in the litigation was a request to limit off-road vehicle travel and/or camping to 15 feet from the center of the route of travel. Fortunately the judge recognized that request as an attempt to misuse the courts to manage federal land. She denied the request. However she did uphold a decision made, based on previous litigation, which will reduce the current limit on camping from 300 feet from the center of the route of travel to 100 feet. Apparently some BLM personnel are quoting the 100 foot limitation as being in place now. By camping within the 100 foot limit no request to move a campsite should occur.
This decision by the judge will remain in effect until after the new Biological Opinion is by US Fish & Wildlife Service. My guess is that when the new opinion is issued additional litigation will be initiated by someone or some group.

Here is a suggestion to make the wet grinding procedure more comfortable. Place water pipe foam insulation over the edge of the water trough for an easy wrist rest while working the stone. Just cut to the length needed and slip it over the edge of the water pan.
Beautiful picture frames can be made from hollow geodes. Just cut and polish a slab, mount a picture and place on a stand.

Henry's Helpful Hints by Henry Wilson:
1. Don't try to cut and polish cabs while watching TV.
2. Most good gemstones can be dug up only during a rain or snowstorm.
3. If you can't identify a mineral, call it jasper. No one else will know either.
4. Don't store tumbled stones in the candy dish.
5. There are approximately 135 ways to polish jade, most of which won't work.

Minutes of the VGMS Regular Monthly Meeting,
Wednesday, January 26th, 2005:
The regular monthly meeting of the Ventura Gem & Mineral Society was called to order by Ed Clark at 730 pm on Wednesday, January 26th, 2005 at the Lexington, Ventura, CA.
The December regular meeting and board meeting minutes were corrected and then m/s/c as shown in the bulletin.
Ed Clark welcomed everyone, introduced guests and began with our salute to the flag.
Richard Bromser gave the treasurer's report for the month of December.
Shirley Layton: The 10th of January will be the deadline for articles and photographs to be submitted for the bulletin.
Shirley Bromser: Club dues are due by the end of March.
Ray Meisenheimer: Ray awarded raffle prizes to a few lucky people and also mentioned that cleanup of the museum is continuing this weekend.
Jim Brace-Thompson: We only have one more club bulletin before our show. Get the word out by use of our flyers or word of mouth. The last show meeting will be on Sunday, February 13th, at Jim's house and will include grab bag arrangement and anything else that we can get accomplished. The presentation for February will be a slide show of shows, with comparisons between then and now of our annual show.
Wayne Ehlers: A sign up sheet for a spring cab class will be available at our show and may help to draw new members.
Mary Polacek next presented a slide show and discussion on the manufacturing of silicon and its use in the making of photo voltaic panels, also known as solar energy panels. Mary and her husband, Paul, work for the local company which utilizes high energy and high temperature to produce the exacting forms. It was all very interesting and our thanks to Mary and Paul for their time and effort educating us on this subject that so closely relates to our hobby.
The next Board meeting will be Thursday, February 3rd, at the new location, the IBEW hall, 3994 E. Main St., Ventura. All are welcomed to attend and the next regular meeting will be held February 23rd at the Lexington.
There being no further business, President Ed Clark adjourned the meeting at 8:55 pm.
Respectfully submitted, Greg Davis.
Minutes of the VGMS Monthly Board Meeting,
Thursday, February 3rd, 2005:
The regular board meeting of the VGMS was called to order by Steve Mulqueen at 7:30 pm on Thursday, February 3rd, 2005, at the IBEW Hall, 3994 E. Main St., Ventura, CA.
Present: Steve Mulqueen, Ray and Florence Meisenheimer, Jim Brace-Thompson, Shirley Layton, Richard and Shirley Bromser, Ron & Jean Wise and Greg Davis.
Steve Mulqueen: For the third weekend in a row, club members worked on the museum and workshop, cleaning up from water damage left by the heavy rains. Schools are waiting to resume tours and we're just about to that point. It was m/s/c to purchase a new vacuum ($85.00 limit) for the museum and suggestions were sought to prevent future damage/vandalism. The canopy was located for use with our ultraviolet light display at our show.
Richard Bromser: It was m/s/c to accept the treasurer's report for the month of January. Milk crates are still not available from Chase Bros. Dairy but Richard will continue with the effort. It was m/s/c to again support the California Mining & Mineral Museum with our donation of $1.00 per VGMS member. The next board meeting will be held at the fair grounds at 6:00 pm.
Shirley Layton: Articles for the bulletin need to be received by the 10th of the month. It's also time for club members to volunteer to provide refreshments and programs for our monthly meetings, so plan on it and contact any board member with your preferred month. Shirley also mentioned that our annual show is listed with the Ventura Chamber of Commerce as an attraction in our city. It doesn't mention "gem & mineral", but Shirley will look into getting that changed.
Jim Brace-Thompson: The next meeting for the 2005 show is scheduled for Sunday, February 13th, 2:00 at Jim's house. All are welcomed. A grab bag stuffing event will be included in this meeting, so bring any inventory you might have for the grab bags. A display has been set up at Wright Library in Ventura and flyers are available to anyone who can help distribute and post them. Jim suggested we develop a club flyer for the purpose of displaying at locations like the libraries.
Ray Meisenheimer will be presenting at 2 schools in Simi and 4 schools are waiting on the re-opening of our museum.
Florence Meisenheimer: We have lots of rock! It's been moved to the front yard in preparation for transporting to our show.
Shirley Bromser: We have 33 paid members so far and dues are due by the end of March.
Ron Wise: The Tijugas Beach field trip has been changed to February 20th.
Jean Wise: Several people have offered to help with the kids' booth at our show and this will help considerably as Jean was pretty well taxed last year by the end of the weekend.
The next meeting will be our monthly general meeting on February 23rd, 2005, at the Lexington in Ventura.
There being no further business, the meeting was adjourned at 8:45 pm.
Respectfully submitted, Greg Davis.

Sometimes symptoms of a stroke are difficult to identify. Unfortunately, the lack of awareness spells disaster. The stroke victim may suffer brain damage when people nearby fail to recognize the symptoms of a stroke. Now doctors say a bystander can recognize a stroke by asking the following three simple questions:
1. Ask the individual to smile.
2. Ask him or her to raise both arms.
3. Ask the person to speak a simple sentence.
If he or she has trouble with any of these tasks, call 9-1-1 immediately and describe the symptoms to the dispatcher. (Webmaster's Note: Call your local medical emergency number whatever it is.)
After discovering that a group of non-medical volunteers could identify facial weakness, arm weakness and speech problems, researchers urged the general public to learn the three questions. They presented their conclusions at the American Stroke Association's annual meeting last February. Widespread use of this test could result in prompt diagnosis and treatment of the stroke and prevent brain damage.

Eyes require protection at all times of the year, whether it is protection from the sun on the way to a collecting site, protection from flying particles at a collecting site, or protection from chemicals, dust, or particles while processing our finds back home in the shop.
Eye hazards include particles, dusts, mists, vapors, fumes, gases, and ultraviolet light. Many of these hazards are encountered by rock hounds in pursuit of their passion.
Safety glasses or spectacles are designed to provide impact protection from flying particles and have heavier frames than normal spectacles with impact resistant lenses, usually of poly carbonate. These lenses can be tinted to protect the eyes from laser or ultraviolet light and the sun's rays. As most particles enter the eyes at an angle, it is recommended that the frames accommodate and are worn with side shields or have them "built in". Safety glasses are available with corrective lenses, even bifocal and multifocal lenses. Do not use spectacles intended for protection from radiation and glare from the sun indoors where your vision may be impaired by the tinted lenses. Spectacles should be fitted to your eye and bridge size and temple length and should fit comfortably over the eyes. The frame should be close to the face and supported by the bridge of the nose. Keep spectacles clean and clear of scratches. Store spectacles in a dry clean place where they will not fall or be stepped on. Scratched or damaged spectacles interfere with vision and do not provide protection for the eyes from fumes, vapors, liquids, and large particles and should be discarded.
Safety goggles provide a secure shield around the entire eye area to protect against hazards coming from many different directions and spread the force of impact over a larger area around the eyes than spectacles. Goggles are most effective when worn with safety spectacles and are also provided with impact resistant lenses that can be tinted if required. Goggles that are unvented or indirectly vented will provide protection from splash hazards. Goggles may be provided with fog free coatings.
Face shields are required when poring hot liquids, using acids to clean rocks or fossils, breaking rocks with hand or mechanical equipment, and while dressing grinding wheels. Face shields should never be used without goggles and safety spectacles and are available with protective head gear and chemical hoods.
Select the proper level of eye protection prior to starting any activity and remember that the risk of bypassing a level because "it will only take a second and I will be careful" could cost you one of your most precious possessions, your sight.
Another word of caution:
Incidents of house fires are cropping up again because of the use of those electric plug-in air fresheners. In some instances the plastic housing of the unit is being melted from the electrical current flowing through it and causing fires. Use caution if you use these products - or better yet, switch to one of the non-electric types.

| These materials may include industrial minerals, ore minerals, fossiliferous rock, mill process waste, waste abrasive compounds, coal-fire power plant waste, chemical additives and rock from all three rock-types including sedimentary, metamorphic and igneous. Most of the commodities required for the manufacture of Portland Cement fall under five general categories: calcium carbonate source, silica source, alumina source, iron source and "miscellaneous": | |
| Calcium Carbonate Source - May include limestone, calcite chalk, marble, marl, sea shells, rock containing fossil shells (in varying amounts), coquina, aragonite sands and/or carbonate slag. Silica Source - May include sand, sandstone, quartzite, kaolinite (high silica clay or claystone), shale, loess, slag, mill fines and/or fly ash (ash from a coal-fired power plant). Alumina Source - May include shale, clay (kaolinite), mud, loess, slag, fly ash, bauxite (aluminum ore), alumina process waste, staurolite and/or granitic mill fines. Iron Source - May include iron ore (magnetite), blast furnace flue dust, pyrite, steel mill scale, blast furnace slag and/or fly ash. Miscellaneous Raw Materials - May include gypsum, fluorspar (fluorite ore), pumicite, calcium chloride, soda ash, borax, diatomite, sulfur, graphite, tar, rosin, synthetic resins, rubber latex, sodium silicate, waste grinding medium and/or waste sand blasting medium. |

| Some of the raw materials are crushed into a fine powder, blended (dry), baked in a rotary kiln and again crushed to a fine powder. Other substances are added with the cement after the baking process. The analysis and testing of raw materials before and after milling ensures good-quality cement with high sheer-strength. Concrete is made by mixing Portland Cement with apportioned amounts of water, aggregate (sand, gravel and/or pebbles) and many other additives. The mixture of raw materials needed at a particular cement plant is dependent upon the availability of those commodities within a reasonable distance from that plant. Most cement plants are located near natural calcium carbonate sources such as limestone deposits. Most concrete mixing plants are located near sources of sand and gravel where abundant volumes of water are readily available. If a cement plant is using a limestone that has some undesirable impurities, some additives may be required in higher concentrations in order to compensate for this factor. In other words, the exact recipe for manufacturing cement at each plant is unique. Each cement plant derives commodities from many sources, using materials that do not have uniform chemical properties. The greatest expenses in mining the raw materials, milling cement and in mixing concrete are in the energy costs associated with these operations. Transportation of raw materials uses up much of the energy requirements. The mining and milling processes also require large amounts of energy for blasting, excavating, crushing, screening, conveying, blending the raw materials and for baking in a rotary kiln. In the concrete mixing plant, energy is required for producing groundwater from wells, crushing rock to make aggregate, washing aggregate, screening, conveying, blending dry cement with aggregate and water and in mixing the concrete prior to loading into a cement truck. Materials that make up the final concrete mix may have come from ten or more different mining operations.

The 2005 CFMS Show will be held in Roseville June 10, 11, & 12. Roseville is located north of Sacramento. Camping areas are adequate, but hook-ups are limited. Besides the usual dealers with everything you could possibly want, and hundreds of beautiful exhibits, a number of excellent programs are planned. One program on gold reports: GOLD - We all want it, we try to find it, but where is it and how did it get there? The speaker is John Clinkenbeard, supervising Senior Geologist with the California Geological Survey. Sounds interesting.

Definition of the Month.
Portland Cement:
Cement - A finely powdered substance manufactured in a cement plant that possesses strong adhesive qualities when combined with water. A calcined (baked) mixture of substances prepared in a rotary kiln (calciner) that is formed into a powder and mixed with water, aggregate (sand, gravel and/or pebbles) and other additives to form concrete. The oldest archaeological evidence of the use of cement is found in what is now known as Syria and dates back to 6500 B.C. Other evidence of the use of cement is found in Europe along the Danube River (5600 B.C.), China (3000 B.C.), Egypt (2500 B.C.), Greece (600 B.C.), and in the Roman Empire (300 B.C.). The Romans used large amounts of cement in forming solid concrete walls. The Coliseum, completed in 82 A.D. in Rome, Italy, was built with large amounts of cast concrete shaped by wooden forms.
Concrete - A complex mixture of apportioned amounts of cement, aggregate, water and other compounds that is used in the construction industry. Concrete will cure to form a hard, permanent substance.
Clinker - Synthetic cement compounds manufactured in a rotary kiln at a cement plant. These compounds may include some or all of the following: tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium-aluminoferrite. Water is added to a powdered form of the clinker with other cement additives. These compounds will react and bind with itself and with sand and gravel in a concrete mix.
Portland Cement - A term first used in 1824 by Joseph Aspdin, an Englishman who was the first to patent a mixture of high-strength cement. He claimed that his cement mortar resembled the natural limestone that was quarried from the Isle of Portland on England's south coast. This term is still used today, in reference to varieties of the common high-quality cement used in concrete.
So, when you purchase a sack of cement at the hardware store, you will know what you are getting for your money!
It has been said that, "Concrete is the 'glue' that holds a city together".
The "Definition of the Month" features words related to geology, paleontology, mining and desert history. Written by Steve Mulqueen for the VGMS, February 2005.
