The Acton Field Trip kicked off with a breakfast meeting of about 28 rockhounds at the Acton McDonalds. In addition to representatives from all three local clubs, there were two members of the Del Air Club, a few pebble pups, several guests and a few dogs on hand to enjoy the hunt.
We visited three sites in the area, all of which are in the open spaces where houses have not yet taken over. The finds were mostly agate nodules. A lucky (or skilled ) few found pieces of saginite.

Minutes of the VGMS Board Meeting,
Thursday, February 7, 2002;
The regular board meeting of the VGMS was called to order by President, Greg Davis, at 7:37 p.m. at the VGMS Museum, 5019 Crooked Palm Rd., Ventura, CA.
Present: Greg Davis, Richard Bromser, Nancy & Jim Brace-Thompson, Ray Meisenheimer, Shirley Layton, David Mautz, Inez Shakman, Wayne Ehlers, Ron & Jean Wise.
President: Greg Davis raised the following topics. Dues have been slow coming in; they are needed soon in order to be able to complete our membership directory. Inez, Shirley, and Ron will be making calls encouraging members to get their dues in soon. Tri-Club Meeting is scheduled for February 23, 10:00 a.m., at the Lexington. Kay Hara of the Oxnard club will be in charge. A Solvang woman is donating some of her family's equipment and rocks to the club. In addition, she has some items for sale. Greg and some other members will be viewing and transporting the materials to Ventura on Saturday, February 9. The Pebble Pups need Federation Rules for Showcases. Ray and Jim will bring copies to the Show Meeting on Sunday, February 10, at 2:00 p.m. Cab classes, instructed by Wayne Ehlers, are scheduled for Monday nights at 7:30 p.m., beginning on March 25. Night guards for the show will be Dave Mautz and Bob Spjut (if available).
Treasurer: Richard Bromser presented the monthly report. A motion to accept the report was approved by the board. The annual report was also presented. Richard has been working on ordering food and organizing materials for the show.
Bulletin: Shirley Layton said the deadline for the next bulletin will be February 10, 2002. She is presently updating the distribution list to include new Pebble Pup parent members and their birth dates. Shirley received a donation of twenty-five semi precious stones by Howard and Sandy Young. They will be used as prizes in the kid's booth and/or as donation awards for the show. Correspondence received in the past month was reviewed.
Federation: Ray Meisenheimer (for Florence) said there was nothing new to report.
Field Trips: Ron Wise outlined the February 16-17 field trip. It will include a geological tour of Rainbow Basin National Landmark and collection in the Coyote Lake site and in sites near the Early Man Site. The Conejo club sponsors the March 9 field trip to Rincon Beach.
Membership: Inez Shakman emphasized the need for those who have not paid dues to do so soon. The Names of five new members (and two pebble pups) were submitted for approval and accepted. They are Laura Bernard (and pebble pup Becky), Don and Lorraine Edmonson (and pebble pups Jonathan and Ashley), Kim Magno, and Donna Stephens. A discussion of dates after which dues are not collected resulted in a consensus that individuals who joined after the November meeting were not to be charged for the remainder of the year. Inez has received donations of Twenty-nine Palms agate from a new closed area and of shark's teeth and some items for the kid's booth.
Show: Jim Brace-Thompson reported on progress on the Show. The following topics were discussed. Contract for the facilities was finalized. The cost was reduced somewhat from the expected $4,000, but is still more than last year. Final planning meeting for the show is scheduled for February 10 at 2:00 p.m. at the Brace-Thompson's home. The layout plan of the facility will be needed at this meeting. Sharon Cunningham, who has graciously accepted the job, will handle hospitality. Show program information is still coming in. Shirley needs complete and final information by February 22 in order to get the programs printed on time. RV Journal printed an article about our coming show. Favors for the show are fossil sand dollars, bought in Quartzsite and mounted by Steve Mulqueen. Showcases: Nancy Brace-Thompson reported that applications for showcases were slow coming in. In the next bulletin she will advertise for additional showcases, request volunteers to work at the show, and request that members bring desserts for the Friday night dinner. It was also reported that, although the exhibit area at the E. P. Foster library was not available this year, it is reserved for February next year.

US Postal Service Irradiation Process May Affect Some Gemstones,
Contributed by Kelly Van Vleck.
Since the recent transfer of anthrax via the mail system, the US Postal Service is seeking ways to protect postal employees and the public from this threat.
Irradiation:
One company with which the postal service has contracted, SureBeam (a subsidiary of Titan Corp.), uses irradiation to kill the microorganisms that often contaminate food. However, this type of ionizing radiation is often used intentionally to change the color of some gem materials - and could produce an undesirable result as well.
Tests run on gems.
Titan uses 5.6 rnegarads. For the initial tests, the GIA had tests run on gems known to be affected by irradiation in a significant way. Three sets of the samples were boxed up in the way that GIA normally ships gems.
Because gems are often shipped through the mail more than once, one package was scanned once, one package was scanned twice, and the third package was scanned four times to see if the cumulative effect of multiple scans caused any significant difference.
After retrieving the packages, they were scanned with a Victoreen model 2W radiation survey meter on the unopened packages as well as the individual stones. No residual radiation was found.
The changes in appearance are noted in the chart at the end of this article. The changes from the one scan to the four scans were similar, though the degree of change was different for some stones.
Implications:
Currently the postal service is scanning only a small portion of the mail and only letters and flat envelopes. Probably nothing will be done to packages that are sent registered or certified [the preferred method for the jewelry industry].
FedEx, US Customs Service, Brinks, Malca Amit, and UPS confirmed that they are not currently using irradiation procedures.
Note that some color changes would not be permanent, some will fade with exposure to light back to their original colors. Others can be changed back with heat. Still others will never revert to their original color. Also note that not all members of the same species or even the same variety will react similarly.

A new bill, HR 2974, introduced recently in Congress has caught my attention. Perhaps you have heard or seen it. This Bill deals with collection of vertebrate fossils and has far reaching consequences. This Bill is in committee in the House and looking for a sponsor in the Senate. If passed it could change the way we collect and sell vertebrate and invertebrate fossils.
I talked to the famous Dinosaur Hunter and Paleontologist, Jack Horner, about this Bill. He said the Bill was designed to stop commercial collectors and not designed to affect amateurs. The Bill has many contradictions and leaves decisions to local land managers to use their own interpretations of the law. Everybody needs to read the whole Bill, but the way it is written is a travesty to rockhounds.
I would urge each of you to write your Congressman and ask that HR2974 be opposed as it is written.

From "Joke of the Day" via the Internet.
Father Murphy was playing golf with a parishioner. On the first hole, he sliced into the rough. His opponent heard him mutter "Hoover!" under his breath.
On the second hole, the ball went straight into a water hazard. "Hoover!" again, a little louder this time.
On the third hole, a miracle occurred and Fr. Murphy's drive landed on the green only six inches from the hole!
"Praise be to God!"
He carefully lined up the putt, but the ball curved around the hole instead of going in.
"HOOVER!!!!"
By this time, his opponent couldn't withhold his curiosity any longer, and asked why the priest said "Hoover"."It's the biggest dam I know."

Fiber optics was developed as a result of the mineral ulexite. Also known as TV rock, it is a hard, brittle, fibrous stone which when writing is placed underneath, will allow the image to appear on the surface of the stone.
This led to the theory that if this type of fibrous material could be manufactured, it could be used in many different ways where image transmission was needed. Fiber optic cables were at first very slender and flexible, used in surgeries and in household decorations.
The manufacturing technology improved and soon manufacturers were spinning out miles of cable for a new application -- data transmission lines. These lines can be up to two inches across. The cable consists of thousands of pairs of optic fibers. Each pair carries data for phone, computer, fax, etc. Since the sides of the cable are reflective, there is no need for insulation or shielding around each fiber, as in old phone lines. This translates to more pairs in a smaller space. For us in the hobby, this created one of the newest gem treasures.
FIBER OPTIC CABS - In order to make a fiber optic cabochon, the cable scraps are first cut into small lengths The cable is then either cut into spheres or it is sectioned parallel to the length of the fiber. Once the slices are made it is cut much like any other gem. However care must be taken to protect the ends of the cable from splintering, catching cutting dirt, abrasives, etc.
There is an interesting thing about fiber optic gems. If you look at them from a 90 degree angle from the eye of the gem, the gem will be transparent to light maintaining its properties for light transmission.

| What it means: |
| 1 = Talc, 2 = Gypsum, 3 = Calcite, 4 = Fluorite, 5 = Apatite (fluorapatite), 6 = Orthoclase, 7 = Quartz, 8 = Topaz, 9 = Corundum, 10 = Diamond. |
Hardness tests of minerals are among the easiest and most useful tests to perform. What rockhounds speak of as hardness is more accurately described as resistance to abrasion. We are testing how easily one substance will scratch another. As an example, copper is relatively easy to scratch, but would you bet on diamond or copper standing up better to blows from a hammer? Hammer blows measure the ease with which something fractures or its tenacity. There are other hardness scales that are based on ease of indentation, resistance to twisting and so forth. For the sake of simplicity and standard usage, in these articles, hardness will refer to the resistance to abrasion as given by Mohs' Scale.
The scale for hardness was published in 1822 by Frederick Mohs, an Austrian mineralogist who got the concept from scratch tests performed by miners. Since Mohs published the scale, it bears his name rather than that of the unknown genius who thought of it. The scale selects 10 minerals as standards, arranging in order these minerals were selected for their abundance, as well as their differing hardness. The scale is uneven. For example, diamond at 10 is much harder then corundum at 9, while fluorite at 4 is only slightly higher than calcite at 3.
A more limited but practical scale can be easily and cheaply obtained by observing your fingernail has a hardness of 2.5, a penny has a hardness of about 3.5, glass and a steel nail have nearly equal hardnesses of 5.5 and a streak plate has a hardness of 6.5. If I carry a nail and streak plate with me and can scrounge up a penny, I've got a handy, light weight mineral testing lab.
More expensive sets can be bought. A set with small samples of all of Mohs' minerals allows a bit more precision in testing. The specimens do lose their usefulness the more they are scratched up in various tests. As an alternative, one can custom build their own Mohs set through collecting or purchasing small fragments of the needed minerals. Other vendors provide sets of hardness pencils with tips of two natural or artificial substances of measured hardness. These are handy in that they are very precise and allow one to test a small surface easily.
Most mineralogy texts give tables of mineral hardness. Particularly complete and useful tables appear in John Sinkankas' "Gemstone and Mineral Data Book". Doing hardness tests requires some technique. You need to find a good surface or edge on your unknown to test. Take care to make sure you are testing the right grain - not the bit of quartz right next to it. In some cases it is easier to scratch the unknown across the standard (the point of a unknown mineral grain across a calcite cleavage). In other cases it is easier to test the standard across the unknown (tip of a nail across cleavage surface of the unknown grain). In an ideal case, you should try to do both to double check your findings. You need to press hard enough to good effect, but not so hard as to fracture either sample. Practice will help you get the proper level.
As a result of your test, you will look for a scratch. Rub aside any powder to see if a distinct scratch has been left. Calcite will leave a trail of powder across quartz. Rub away the powder and you'll see the quartz is unharmed. A hand lens will help you see the scratch. In this way you can bracket the hardness of your unknown between two of your standards (harder than a fingernail, softer than a penny). The ease with which one substance scratches another is also useful. Quartz easily scratches calcite, telling you of a large hardness difference. Quartz will scratch feldspar with much more difficulty. When testing a standard against an unknown that is of equal hardness, both substances will leave shallow scratches on each other.
The hardness of a particular mineral may vary with direction within the same grain. Kyanite is a good example. Kyanite generally occurs in long bladed crystals. The hardness taken the short way across the blade has a hardness of 7 the hardness taken the long way along the same grain will be 4.0. Muscovite is another good example of this. Its hardness is 2.5 when taken across a flat surface of a cleavage sheet, but 4 when taken across the grain of a book.
The reason hardness varies in this way is that the phenomenon depends on the strength of the bonds holding the mineral together. The bond strength can be significantly different in different directions in the minerals giving the different hardness. In most minerals this difference with direction is minor and doesn't affect the test. In the case of kyanite, this difference in hardness is a confirming test.
Some minerals' hardness may vary from sample to sample depending on that mineral's exact chemical composition. Hornblende's hardness can vary from 5 to 6 meaning some hornblende is softer than glass, some harder. This reflects the fact that hornblende can accommodate varying amounts of sodium, calcium, iron and magnesium in its structure, which affect the details of its chemical bonding, hence its hardness
Testing hardness of rocks is less effective than testing hardness of minerals. A rock is basically a mixture of various minerals, although it can contain non-mineral materials such as natural glass and fossils. (Fossils aren't minerals because they are organic, while glass isn't a mineral because it lacks an internal crystalline structure). Let's take a granite pegmatite for example. This might contain grains of topaz (H=8), quartz (H=7), feldspars (H=6) and muscovite mica (H=2.5). You could thus get a range of hardness depending on which grain you tested. In a coarse grained rock, identifying the individual minerals allows you to identify the rock. If the rock is fine-grained, it's harder to interpret results.
The hardness of fine-grained rocks tends to reflect the average hardness of the minerals in them. Shales are made mostly of clay and tend to be soft. Limestones and dolostones are also soft, with a hardness of 3-4. Just watch out if quartz sand is present mixed with the carbonates! Quartzite and chert being made mostly of quartz are both very hard. The hardness of sandstone may be difficult to test. If the sand grains have not been cemented well or have been cemented by calcite, the sandstone will seem softer. The individual quartz sand grains will still have a hardness of 7, but the rock may crumble or disaggregate in your hand, making it look soft. If you think it is really soft, trying dragging the disaggregated sand grains across a piece of glass and you'll readily see the effects. Most igneous and metamorphic rocks contain much feldspar, quartz, pyroxenes and amphiboles. Their hardness is thus going to be between 6 and 7. This means hardness is not a good way to distinguish one of these rocks from another. Volcanic glass will typically have a hardness of 5.5 - 6.0 depending on its particular chemical composition.
The hardness or rocks and minerals is also dependent on the degree of weathering. Weathering may convert feldspars (H=6) to clay minerals (H=2-3) Even corundum (H=9) can alter and have rims of softer minerals such as margarite (H=3.5-4.5) around it. This is why it is important to test as fresh or unweathered a surface as you can while doing hardness tests. Mohs' scale has stood the test of centuries as a useful tool.

Carmelita Swarts of the San Diego Mineral & Gem Society began this project in 1984 because the SDMG club was hosting the AFMS/CFMS National Show. We thought it would be great to have this event coincide with the show. We had a wonderful "lady" Assemblywoman, Lucy Killea from San Diego and "Rusty" Areias from the 25th Assembly District, San Benito County carry the bill SB-2404 through the Assembly. They didn't have any trouble with the Assembly. We were shot down in the Senate. We had failed to realize that we needed a Senator to also sponsor the bill.
In the Sacramento Bee, Monday July 2, 1984 "Assemblywoman Lucy Killea's bill to declare Benitoite as the State Official Gemstone was laughed to death Friday." The bill was unanimously approved by the Senate Judicial Committee. It should have been a consent item. By the time Mrs. Killea learned of the action it was too late to request a re-hearing. The budget, as usual, had drained the energy from the Senators, and it was closing time. There were also two other bills for the state to recognize - they were for folk dancing and grass. (Don't know, but think this was some sort of native grass, not "the" grass!)
The Nielsen, Napa and other areas around there following Senate members voted NO: Ayala, Los Angeles / San Bernardino; Carpenter, Orange; Dills, Los Angeles; Greene, Los Angeles; Hart, Los Angeles / Santa Barbara; Keene, DelNorte / Mendocino / Sonoma; Russell, Los Angeles; Vuich, Fresno, Tulare; Johnson, Butte, etc; Lockyer, Alameda; Maddy, Fresno / Maders; Marks, San Francisco; Montoya, San Francisco; Roberti, LosAngeles; Rosenthal, Los Angeles; Seymour, Orange; Speraw, Los Angeles.
The bill was again introduced in 1985 by Rusty Arias and Lucy Killea. This time the entire CFMS was willing to work to get this bill passed. The names of those who had voted no were lobbied. This time the Bill was AB-2357. Charles Leach, CFMS President, 1984 went to Sacramento to lobby as well as those who lived in or near Sacramento. The bill finally passed the Senate on Wednesday, Sept 11, 1985. The Governor signed the bill on October 1, 1985. Those voting in the negative this time were: Boatwright, Contra Costa; Lockyer, Alameda; Presley, Riverside; Seymour, Orange; Stem, Kern / Kings / Los Angeles.
Not voting were: Ayala, Los Angeles / San Bernardino; Foran, San Francisco; Garamendi, Alpine, Amador etc; Green, Sacramento; Hart, Los Angeles; Montoya, Los Angeles; Nielsen, Butte / Colusa, etc; Richardson, Inyo / Los Angeles; Rosenthal, Los Angeles; Russell, Los Angeles; Vuich, Fresno, Tulare.
There is a beautiful specimen in the Los Angeles County Natural History Museum that is on loan from the CFMS. It is taken each year from there to the CFMS convention, and then returned.

Mineral Oil has many uses. It is fine for preserving borax crystals from hydration changes. It makes varicite a deeper green, and improves the appearance of fluorite and calcite.
When shaping and polishing your stones, do not press hard. Let the machine do the work. By pressing hard all you do is wear out the wheels, yourself, and cut deep scratches in the stone. You have better control over your work with a light touch.
