Thank you to all our wonderful volunteers who have helped us fill our slate of programs for this year.
Submitted by Nancy Brace-Thompson, Program Chair.
The suggestion was made to bring back the not so annual VGMS BBQ.
The occasion is scheduled for Sunday, October 26.
The place is Arroyo Verde Park in Ventura at 12 Noon.
The club will provide Hotdogs, hamburger and buns.
You will provide one side dish and the rest of your needs for a picnic.
It's hard to believe it is getting to be that time again. We will need a nominating committee selected at the September meeting. Be thinking about whom you would like to see on the VGMS 2004 Board and what you would like to do. The more active you are the more fun you have. The Election Schedule is as follows:
September - Nominating Committee appointed,
October - Nominating Committee presents slate of Officers,
November - Election of Officers,
December - Installation of new Officers.
If you are approached to take an office, please accept or if you aren't approached and would like to be an officer please contact the nominating committee or Ray Meisenheimer. We have a great club that is fun to work with and very educational. It takes everyone's help to keep it that way.

Artie had died and gone to heaven and of course his wife Elsie was heartbroken. Several nights later she was sleeping and suddenly heard Artie calling to her. She answered him back, "Is that you Artie?" He answered "Yes it is, I came back to comfort you." Elsie asked "Well how is it up in heaven?" "Well everything is just wonderful, the scenery is great, the food is wonderful, and I get to play golf or tennis anytime I want. Now if it hadn't been for that awful oatmeal diet I could have been up here 10 years ago."

If you have thought about buying a meteorite, but have concerns about authenticity, or perhaps bought one that you suspect may be a meteor-wrong, the International Meteorite Collectors Association may be of help to you. Look for their logo whether you're shopping on-line or at a Gem and Mineral Show. Their main purpose is to make certain that all the members adhere to the highest standards of meteorite identification, authenticity and proper labeling practices. The members monitor each other's activities for accuracy. Some are professional dealers, some educators who use meteorites in their teaching, while others are mainly hunters. If one of the members knowingly defrauds someone (member or not), that person will be removed from the IMCA. Their Complaints Page says: "If you have bought a meteorite from a member of the IMCA and feel that you have somehow been defrauded as in: the rock you bought isn't a meteorite, isn't the meteorite that you thought you were buying, or was the wrong weight, and the seller will not take reasonable action to correct the situation, e-mail us at email@example.com."

The October birthstone is the Opal and the flower is the Calendula.
Chemistry: SiO2-nH2O; Hydrated Silicon Dioxide.
Uses: As a gemstone and ornamental stone.
Group: Some mineralogists place Opal in the Quartz Group.
Opal has been a popular gem for many centuries and has a very interesting structure. Opal is considered a mineraloid because this structure is not truly crystalline. The chemistry of Opal is primarily SiO2 and varying amounts of water. The amount of water varies from 5 -10% and greater. This water can help geologists determine the temperature of the host rock at the time the opal formed.
Although there is no crystal structure (meaning a regular arrangement of atoms), Opal does possess a structure nonetheless. Random chains of silicon and oxygen are packed into extraordinarily tiny spheres. These spheres in most Opals are irregular in size and inconsistent in concentration. Yet in Precious Opal, the variety used most often in jewelry, there are many organized pockets of the spheres. These pockets contain spheres of approximately equal size and have a regular concentration, or structure, of the spheres. This has the effect of diffracting light at various wavelengths, creating colors. Each pocket produces a different color, with a different intensity depending on the angle from which a viewer sees it. The multicolored flashes of light that Opal emits gives it a truly beautiful and valuable look.
Color is white, colorless, pale yellow, pale red, gray or black when impurities are common. Diffraction can cause flashes of any color of the rainbow (opalescent).
Luster is vitreous to pearly.
Transparency: Crystals are transparent to translucent.
Crystal System does not apply because opal is amorphous.
Habits include massive, cavity-fillings such as in fractures and geodes, nodular or as a replacement of other minerals and wood.
Cleavage is absent.
Fracture is conchoidal.
Hardness is 5 - 6.
Specific Gravity is approximately 2 - 2.5 (light).
Streak is white.
Associated rocks are chert (a form of microcrystalline quartz), volcanic rocks and many others.
Other Characteristics: Some opal fluoresces and it can be very sensitive to impacts and low temperatures.
Notable Occurrences include Western USA; Mexico; Australia and many other localities around the world.
Best Field Indicators are color play (opalescent), low density, lack of cleavage and crystal faces and fracture filling tendency.

Our August meeting was blessed with twenty members, six guests and one pebble pup. The guests include Richard Cronin, Fred Yilla, Ed Gafford (our speaker), Carol Gafford, Heidi Mauer and Andy Pletcher. Andy and her son Savvy have become new members and I understand Heidi is becoming a new member as well. The pebble pup was Savvy. We are certainly happy to welcome all our guests (and new members) and hope they will join us again. Sorry if we misspelled any names, they are kind of hard to read some times. Sharlyne reported that the program was most interesting and that a 60th anniversary cake for Ray & Florence Meisenheimer, furnished by Greg and Valli Davis, was enjoyed by all. Congratulations Ray and Florence, sorry to miss the celebration and the program. However, we did enjoy our vacation to Iowa via Amtrak and hope to have some pictures of the beautiful Donner Pass area from the train perspective for you all. I look forward to seeing all of you at the September meeting.Table of Contents.
Because of Earth Science happenings at Camp Paradise and other events scheduled for September there is no fieldtrip scheduled for September.
Mark your calendar for October 4-5 for a dig in Bishop and Lone Pine.
We are planning to spend the 27th-30th of November in the North Cady Mountains.
Note: October 11-12 is the Gem-O-Rama at Searles Lake. Check with Steve Mulqueen for information. Bring back all the extra Halite you can as it sells at the show.

A woman received a phone call that her daughter was very sick with a fever. She left work and stopped by the pharmacy for some medication for her daughter. She returned to her car to find she had locked her keys inside. She had to get home to her sick daughter, and didn't know what to do.
She called her home to the baby sitter, and was told her daughter was getting worse. She said, "You might find a coat hanger and use that to open the door." The woman found an old rusty coat hanger on the ground, as if someone else had locked their keys in their car. Then she looked at the hanger and said, "I don't know how to use this." She bowed her head and asked God for help.
An old rusty car pulled up, driven by a dirty, greasy, bearded man with a biker skull rag on his head. The woman thought, "Great God. This is what you sent to help me?" But she was desperate, and thankful. The man got out of his car and asked if he could help. She said, "Yes, my daughter is very sick. I must get home to her. Please, can you use this hanger to unlock my car." He said, "SURE." He walked over to the car and in seconds the car was opened. She hugged the man and through her tears she said, "THANK YOU SO MUCH... You are a very nice man." The man replied, "Lady, I ain't a nice man. I just got out of prison for car theft." The woman hugged the man again and cried out loud..."THANK YOU GOD FOR SENDING ME A PROFESSIONAL!"

Searles Lake is an evaporite basin located near the community of Trona in San Bernardino County, CA. IMC Chemicals currently extracts 1.5 million tons of industrial minerals each year from several lakebeds within the basin.
Searles Lake is one of a chain of Pleistocene lakes that extends from Owens Lake to as far as ancient Lake Manly in Death Valley. The stratigraphic record at Searles Lake indicates that it once held brackish water as deep as 200 meters (650'). Fluctuations in lake levels correspond to the advances and retreats of glaciers in the Sierra Nevada Range. Thirty major lake levels occurred during the last 150,000 years, represented by a sequence of salt and mud beds. The precipitation of minerals occurred during long periods of lake evaporation.
Borax was first produced from the dry lake surface in 1873 by John Searles under the name of the San Bernardino Borax Mining Company (SBBMC). Searles was the first to haul borax using the famous 20 mule team wagons. In 1873, before the railroad was built to Mojave, refined borax was hauled 175 miles by 20 mule teams from Slate Range Playa (now called Searles Lake) to the harbor at San Pedro.
Searles Lake is a vast resource of sodium and potassium minerals of the carbonate, sulfate, chloride and borate system of mineralogy. Production of industrial minerals involves a complex solution mining operation in which brines are produced from wells completed in several salt beds at depths of over 100 meters below the surface. A network of production wells, injection wells, solar ponds and piping are used in the extraction and treatment of the brines.
Industrial minerals are extracted from the brines at the Argus, Trona and Westend plants. Minerals are crystallized from the brines, washed, screened and dried in rotary kilns. This complex extraction process at the 3 plants is generally referred to as fractional crystallization. It includes the treatment of brine through carbonation extraction, refrigeration extraction and/or solvent extraction. Salt is harvested with use of heavy equipment from the lake surface and from solar ponds.
IMC Chemicals products from Searles Lake include borax, V-Bor (borax w/5 moles of water), anhydrous borax, boric acid, soda ash, salt cake and salt. Mineral reserves exceed 4 billion metric tons.

Demand has been high for the opening of the Big Room in southeastern Arizona's Kartchner Caverns near Benson, officials say.
Kartchner Caverns is a limestone cavern system in Southeastern Arizona discovered in 1974 by two amateur cavers from Tucson. It is host to world-class cave formations considered to be the best of their kind in the world.
The Big Room, at the end of a 1,220-foot trail, will open to the public for the first time Nov. 11. The big Room covers a much larger area than the Throne/Rotunda rooms combined, but provides a more intimate setting with a diverse selection of formations.
A fund-raising sneak preview of the Big Room is being offered Nov. 8-9 through the Friends of Kartchner Caverns and Arizona Diamondbacks Charities for $150.
For information, call 800 285-3703 or go to www.azstateparks.com or www.explorethecaverns.com on the Web.
From The Star, Sunday Aug. 31, 2003, submitted by Emma Mayer. (Ed. Note: Wayne and Marie Ehlers visited the cave and Wayne gave a program on it about a year ago. It appears to be an outstanding place to visit.)
Marble is a metamorphic rock composed wholly or in large part of calcite or dolomite crystals, the crystalline texture being the result of metamorphism of limestone by heat and pressure. The term marble is loosely applied to any limestone or dolomite that takes a good polish and is otherwise suitable as a building stone or ornamental stone.
Marbles range in color from snow-white to gray and black, many varieties being of some shade of red, yellow, pink, green, or buff; the colors, which are caused by the presence of impurities, are frequently arranged in bands or patches and add to the beauty of the stone when it is cut and polished.
Marble is used as a material in statuary and monuments, as a facing stone in buildings and residences, and for pillars, colonnades, paneling, wainscoting, and floor tiles. Like all limestone, it is corroded by water and acid fumes and is thus ultimately an uneconomical material for use in exposed places and in large cities. The presence of certain impurities decreases its durability.
Marble was extensively used by the ancient Greeks; the Parthenon and other famous buildings were constructed of white Pentelic marble from Mt. Pentelicus in Attica, and the finest statues, e.g., the Venus de Medici, from the remarkably lustrous Parian marble from Paros in the Cyclades. These same quarries were later used by the Romans. Among the famous marbles of Italy are the Carrara and Siena marbles of Tuscany, which were used by the Romans and the Italian sculptors of the Renaissance. Marbles are quarried in all parts of the world. The finest marbles in the United States come from Vermont, which produces large quantities. Other states important as marble producers are Massachusetts, Maryland, Tennessee, Alabama, Georgia, Missouri, California, Colorado, and Arizona.

Minutes of the VGMS Regular Monthly Meeting,
Wednesday, August 27, 2003:
The regular monthly meeting of the Ventura Gem & Mineral Society was called to order by President Ray Meisenheimer at 7:35 pm on Wednesday, August 27, 2003 in the Bijou Room of the Lexington, 5440 Ralston, Ventura, Ca. The group was led in the salute to the flag.
The July regular meeting and board meeting minutes were corrected and then m/s/p as shown in the bulletin. Guests were welcomed.
Ray asked for but received no old business.
Richard Bromser gave the treasurer's report.
Jim Brace-Thompson - The next show meet for our 2004 show will be September 21st at the Brace-Thompson's house at 2:00 and plenty of flyers have been printed and are available for distribution at other shows.
Ron Wise - No field trip scheduled for September due to Camp Paradise, the Lone Pine trip is planned for October 4th & 5th and Ron also mentioned that the Club picnic has been scheduled for Sunday, October 26th, at Arroyo Verde Park in Ventura. Details will follow, but you can pretty much figure on a very relaxing and enjoyable time with perfect weather during this time of year. It's a perfect setting, so mark your calendars. The club will provide hot dogs, hamburgers and buns with each family bringing a side dish to share. See you there.
The 10th of the month is again the deadline for articles submitted to the bulletin.
Ed Gafford, an artist and chemist combined the two and presented an excellent program of color and science. Digitized photos of common chemicals in crystal form, enlarged many times demonstrated some of beauty in nature, seldom seen. Ed presented a slide show along with hands-on displays for everyone to view. It was as educational as it was entertaining.
Steve Mulqueen mentioned the Trona show coming October 11th & 12th and that he and Susan have set up a new display of nodules and geodes at the Santa Paula Oil Museum.
Ray Meisenheimer announced the need for volunteers to fill nomination positions and the committee to put this together. All and any help is appreciated. The next Board meeting will be September 4th, all are welcomed to attend and the next regular meeting will be September 24th.
Door prizes were awarded and refreshments were provided by Greg and Valli Davis, who presented Ray and Florence Meisenheimer with a 60th wedding anniversary cake. (Florence's favorite-lemon filling.)
There being no further business, Ray adjourned the meeting at 9:20 pm.
Respectfully submitted, Greg Davis.
Minutes of the VGMS Board Meeting,
September 4, 2003:
The regular board meeting of the VGMS was called to order by President Ray Meisenheimer at 7:30 pm on Thursday, September 4, 2003, at the VGMS Museum, 5019 Crooked Palm Rd., Ventura, Ca.
Present: Ray and Florence Meisenheimer, Richard Bromser, Steve Mulqueen, Nancy Brace-Thompson and Greg Davis.
Richard Bromser - Checks 1045-1047 were m/s/c to be used for club utilities and expenses for the month of August. A discussion followed concerning the possibility of relocating club funds to increase interest rates. Further discussion will be needed. It was m/s/c to accept club member applications from Savvy Pletcher (11 years old) and Andy Pletcher.
Nancy Brace-Thompson - 10th of the month is deadline for articles to the bulletin. The next show meeting will be September 21st, 2:00 at Nancy's house.
There are no field trips planned for September as Camp Paradise will require our time. The next scheduled trip will be to Lone Pine, October 4th & 5th (details coming) and the Trona Show, Oct.11th & 12th. A possibility would be a trip in November to the Cady Mountains.
Steve Mulqueen - A workshop day will be scheduled in the fall to repair the museum roof. The Trona Show (October 11th & 12th) always signals the cooler time of year when we're able to return to the desert.
Ray Meisenheimer - October 26th has been set as the date for a club picnic at Arroyo Verde Park in Ventura. Details will be forthcoming but we'll probably converge on the place around noon. The regular meeting for November (the second Wednesday) will include our club silent auction and home made pumpkin pies from members. Speaking of November, we'll vote on club board member nominees during that meeting, with nominations starting at our September meeting and the installation during our December meeting. See you all there.
There being no further business, the meeting was adjourned at 8:25 pm.
Respectfully submitted, Greg Davis.
AFMS Newsletter - March 2001.Table of Contents.
"TV ROCK" can be seen in many shops and specialty stores dedicated to things of nature. Those of us that are curious about such things often pick it up. Upon further investigation we find that when we place the piece upon some printed material the image is transmitted to the surface nearest to us.
Wow! Now we see why it has the nickname of "TV ROCK". If you have done this and had a similar response, have you ever wondered how this occurs? I have and wish to share my findings.
"TV ROCK" is really a borate mineral named ULEXITE. Many of the borate minerals occur in little puffballs of very fragile-looking white crystals. The spray of crystals gives the puffball appearance. This material is formed in open pockets or cavities in the host material. The white is often a startling white that catches one's eye immediately.
The crystals are formed in the triclinic crystal system, which has no two-axis equal, and therefore a crystal that has no symmetry. The fact that it has no symmetry does allow it to have parallel faces, which are called pinacoid faces.
This triclinic group of crystals is so compactly packed that they form these layers, with all crystals being parallel to each other. Thus, if some of our material is sliced parallel to these crystals and we make a cabochon of this material we will obtain a cat's eye affect from the parallel crystals.
These are quite pretty, as the basic form will show a whitish color similar to that seen in moonstone and a vivid white eye will follow you around as you move the cabochon.
If the material is cut perpendicular to the crystals and we polish both sides of our slice, we have now polished the ends of the individual crystals. Doing this provides a nicely polished surface, but with nothing very noteworthy. However, when we place one of the polished surfaces upon a piece of printed matter, we see the "TV" phenomenon. The image that we have placed the piece against is now seen on its upper surface. This occurs because the clearness of the ULEXITE crystal allows the image to flow from the surface touching the printed matter through the crystal and then be displaced on the surface nearest to us.
All of this is due to the parallel faces provided by the triclinic crystallization of the ULEXITE and produces our "TV ROCK".
This very same phenomenon is observed in the fiber optics part of the electronics industry where electronic data is passed down fiber tubes similar to our crystals in "TV ROCK" and the fibers are usually tightly packed similar to our ULEXITE and both produce the same optical events.
Dense layers of ULEXITE are found at the Borax Mining operation near Boron, California and the layers can be as small as an inch or so in thickness to as large as several feet thick. Neat stuff; don't you agree?

Burp that tumbler! - If your tumbler keeps burping gas and making a mess---it's due to gas generated by acids and metals such as the iron in a stone, reacting with the weak acids formed by grinding other rocks.
Drop a couple of antacids in the tumbler and the problem will be reduced or go away!
Tums for the tumbler!
Brecia-4/03 via Del Air Bulletin 9/03.
Keep chiggers and ticks away by dusting your shoes and trouser legs with powdered sulfur. Have your druggist mix one part of benzoate and eight parts of denatured alcohol. Shake it well and spray it on your shoes, socks and clothing, inside and out. Allow it to dry. One spraying will last until laundered, and it will not harm fabrics or colors, or you. - Author unknown - The Petrified Digest 6/02 via Quarry Quips 7/03.
Instead of dumping used acid (oxalic, muriatic, etc) down the drain, where it can cause pollution and might damage the plumbing, try the following: put it in a plastic bucket or earthenware (do not use metal) with a piece of limestone. The limestone will neutralize the acid so that it can be safely dumped almost anywhere. - Author unknown - The Petrified Digest 6/99 via Quarry Quips 7/03.
As part of our publicity campaign for our show, Jim Brace-Thompson had a great idea to share more complete show information with other clubs as an insert into their bulletins. The response we had to that was great. The Editors were happy to publish our information as an exchange for their show information. We are happy to reciprocate with the following show information.

Definition of the Month.
The in-place dissolution of water-soluble mineral compounds from an ore deposit. Some solution mining operations involve the use of chemical solvents that increase the solubility of ore minerals or cause an ion-exchange reaction. Most solution mining operations involve the injection of solutions and the production of saturated liquids with the use of a system of wells completed within the ore deposit. Mineral compounds are extracted from the saturated solution by means of chemical reactions that cause a decrease in solubility and the precipitation of the desirable mineral compound.
The "Definition of the Month" features words related to geology, paleontology, mining and desert history. Written by Steve Mulqueen for the VGMS, September 2003.
Illustration of the Month.

Brachiopods refer to any solitary marine invertebrate belonging to the phylum Brachiopoda. They are characterized by two bilaterally symmetrical valves on their shell. Brachiopods are well represented as shell fossils ranging in age from lower Cambrian to Holocene. Brachiopods still exist today in isolated regions of the oceans of the world.
The "Illustration of the Month" features a drawing, sketch, pen & ink rendering or an engraving print rediscovered in books, maps, manuscripts and other sources related to geology, paleontology, mining and desert history. Written by Steve Mulqueen for the VGMS, September 2003.
