Check out some great pictures from the gem tree class held at Dave and Lenora’s place last month! page 3 1 2 Arkansas Rockhound News March 2014 Aquamarine! President’s Message Mike Austen, CAGMAGS President The February meeting was a very interesting one. It was the first meeting in the new improved Terry library meeting room. The lighting is much improved, new tables and very comfortable chairs, and a new video projection system. Come check it out for yourself at our next meeting on March 25th. The next meeting will be a club auction, always a big hit and a lot of fun. Bring up to five items for sale, and your allowance money to spend. This is your chance to collect all those items from places you have never been to, or clean out all your extra rocks that are just taking up space in your garage. The committee that is working on ways to bring our club and the UALR geology department closer, gave its first report. I was excited by all the possible projects that were brought up. In the future, this will be a great partnership and a wonderful thing for all of us. - Mike Can you guess this month’s Mystery Rock? Hint #1 – This rock is made of nearly 100% plagioclase feldspar Hint #2 – The first two numbers, 1 & 5, refer to the mission number Hint #3 – Not actually made of cheese afterall! Answer on page 7 2 Arkansas Rockhound News March 2014 GEM TREES 101! HELLO CAGMAGS PEOPLE! IF YOU MISSED THE GEM TREE CLASS I’M SO SORRY FOR YOU! WE HAD A BLAST!

THEY EVEN FED US AFTER ALL OUR HARD WORK IN CLASS! IF ANYONE WANTS TO LEARN HOW TO MAKE GEM TREES WE CAN SCHEDULE ANOTHER CLASS. JUST LET THE MURRAY’S KNOW. THANKS BUNCHES YA’LL! STEPHANIE 3 Arkansas Rockhound News March 2014 BUY – SELL TRADE LIKE TO SWAP? To Be or Not a Bee How can a bumblebee be jasper? Well, if you said it couldn’t be, you are right! “Bumblebee Jasper” or “Bumble Bee Jasper” is still considered a baby in the rock world, because it has only been known about since the late 1990s. It gets its name from the alternating yellow, orange, and black layers that remind you of a bumblebee and has a wide variation in colors and patterns. Actually, it isn’t true jasper because it does not consist primarily of microcrystalline quartz. It is actually a indoagate.com/bumblebee.html sedimentary rock that contains sulfur (yellow), manganese oxides (black), realgar and orpiment (arsenic-sulfide minerals; orange), and calcite and aragonite (calcium carbonate minerals; what holds it all together!). “Bumblebee Jasper” is a porous, layered, multi-colored rock found only in the volcanic environment of the Indonesian island of Java. It has a Mohs Hardness Scale value of about 4.0, making it about the same hardness as fluorite. It is used as a gemstone, and is usually coated with clear epoxy resins to enhance stability, colors, hardness, and to eliminate porosity. Most importantly, the coating protects the wearer from arsenic poisoning! “Bumblebee Jasper” is highly collectable because of its unusual formations, colors, patterns, and availability.

We are now back in our regular meeting place after the renovations. The floors are refinished, there are new chairs and tables, and a new overhead video projector. We welcomed visitors Andrea Smith and her daughter Aaliyah. Aaliyah is a very interested young rockhound, so we hope they will join the club. Mike A announced several events coming in Our swap April Siloam Springs April Stillwater, OK April Memphis, TN April April: 12 12 & 13 19 26-27 Mike D reminded us of the Earth Talk lecture series at UALR. (more elsewhere in the bulletin) There is one on March 5th and another on March 19. They are free and we’re welcome to attend. Old Business: Dues are past due now. If you can’t make it to the meetings, mail your dues to P.O. Box 241188, Little Rock, 72223. Individual is $15 and family is $25. The Scholarship Committee met at UALR. Mike DeAngelis gave a summary of the discussion, which centered on developing and strengthening the relationship between the club and the UALR faculty and students. One of the many things we have in common is field trips, and they discussed possibly coordinating some. Also UALR could do workshops for our club in their lab facility, and we could show the students about lapidary work on their equipment. Mike noted that people over 60 can take UALR classes tuition free. He also said interested people could just sit in on some geology classes. Their students have been helping at our show, and now UALR people produce both our newsletter and our website. It was suggested that we try to meet out there in their lab on a Saturday each month. Volunteers that will be helping with the Boy Scout Merit Badge program May 10th are Stephanie, Barbara, and David Hodges. They’re taking over from Pat and Lenora, who couldn’t do it this year. Volunteers are needed for the rock swap. There was some question on the hours of the swap. Mike A will consult with NLR Parks and put out the info. Reports: Sec/Treas—treasurers report on the club table, approved. Library—several new magazines are in Field trip—there was no trip, due to weather. David Hodge is working on one for March 15, to be announced. Next program—March will be a club auction. Each member can bring up to 5 items to auction. The club keeps 10%. Bring money, preferably smaller bills and quarters. Good bargains usually happen. (Advice to newbies—high reserve items usually don’t sell well) (CONTINUED ON PAGE 6) EARTHtalk!

(nice work!) and Lenora Murray brought photos of their recent gem tree workshop at their house. Program: February’s program was a video of Gene Meieran, well known collector, at the 2013 Dallas Mineral Symposium talking about another well known collector, Wayne Thompson, author of the book IKONS, and showing photos of some of those iconic mineral specimens. Those are a bit pricy for ordinary mortals, but its nice to see what the top quality minerals look like. Addition to January minutes: Sarah Dodson suggested the club make a donation to Pulaski Humane Society in memory of member Ron Wilhelm, as it was a favorite charity of his and Virginia’s. The club approved $50 to be donated. Submitted by Sarah Dodson, Sec/Treas WHICH CAME FIRST? The dinochicken (trex henus) or the rock egg (hardest doneus) To get to the bottom of this important issue, we must first ask some tough questions. What is a rock egg? Where do they come from? What are they good for? Why would anyone want one? A rock egg is an egg made from stone. It has long been thought that they first came from the attempts of some poor clueless rock hound who was trying to create a sphere or some marbles, and just could not get it right. It is widely known that those who play with rocks are a few marbles short. They make great Easter eggs, some are even dyed pretty colors, for those kitchen divas that cannot boil water. They can also be placed in a nest if you want to drive some poor bird crazy trying to hatch one. Some of us like to collect them just because. Because rock hounds will collect just about anything rock related, and all have there own personal tastes, even if rock eggs are not very tasty. So as to which came first just remember you can turn a dinochicken fossil into a rock egg, but you cannot hatch a dinochicken from a rock egg. If you are still confused, here are the famous words of the great rock collector William Shakestone: “To be egged or not to be egged, that is the question. Whether it is nobler for the rock to suffer the outrageous grinding and polishing of some lapidary craftsman, or just remain a natural specimen. To rock, to egg, to rock no more.“ Submitted by Mike Austen CAGMAGS membership dues are now due! 2014 Membership Rates If you would like to continue to receive the benefits of CAGMAGS membership (including this newsletter), please send your check made payable to CAGMAGS at: Individual membership = $15 Family membership = $25 CAGMAGS, P.O.

Visitors and pebble pups are always welcome. BenchTips by Brad Smith SECRET INGREDIENT Those of us who use paste solders sometimes find an old tube has dried out. There should be some way to recondition it, but what to use? Calling tech support at the suppliers didn’t work for me. Either they don’t know what the ingredient is or won’t tell you the secret. None of us likes to waste and expensive material - $16 – 20 a tube, so I’ve often experimented with ways to rejuvenate it. Mixing in a liquid flux doesn’t work. When the liquid starts to boil off, it spatters the solder in all directions. But after several failed experiments I finally found a way that does work. My secret ingredient is petroleum jelly. Mix in just enough to restore the consistency to something that’s usable. If you use too much, the lump of solder will flow over a wide area as soon as the torch starts heating it. If your solder is in a syringe, it can be a little difficult to get the plunger out. I find the easiest way is to poke a hole through the solder from the tip to the rubber plunger (a bur shaft was the right size for my tube). The hole allows air to enter between the solder and the plunger, allowing the plunger to be slowly withdrawn. Once the solder is out of tube, you can easily add the Vaseline, mix it up, and spoon it back into the syringe.

It was originally thought they had found a piece of the Moon’s primordial crust, but later analysis initially showed that the rock was only 4.1 ± 0.1 billion years old, which is younger than the Moon itself.
