News Nuggets November 2010 News Nuggets Newsletter of the Albuquerque Gem & Mineral Club Volume 57 Number 11
NEXT MEETING: Monday, November 22, 2010 The Albuquerque Gem & Mineral Club meets on the 4th Monday of the month. All meetings are held at the New Mexico Museum of Natural History, 1801 Mountain Road NW in Old Town, Albuquerque, New Mexico. The entrance is on 18th Street. The meeting begins at 7:30 p.m. in the Sandia Room on the 2nd floor. There is a short business meeting prior to the evening’s presentation, which begins at approximately 8:00 p.m. The Junior Club meets at 6:30.
GENERAL MEETING FEATURED PRESENTATION “Snakes Alive!!” by Bob Myers Director, American International Rattlesnake Museum Our guest for the final program of the year is Bob Myers, who is in charge of the largest collection of different species of live rattlesnakes in the world, right here in Albuquerque. At the American International Rattlesnake Museum, species from North, Central and South America are presented in recreated displays of their natural habitats, along with a wealth of information about the ways that rattlesnakes and other often-feared creatures influence our lives, in many surprising and beneficial ways. Bob will educate us about snakes and other surprises we might encounter on field trips or even in our own backyards, and give us some tips on handling these interactions safely, without danger to us humans or the species we share our environment with. He will also bring a sampling of live snakes (and who knows what else?), so people who dare can get up close and personal with some of the world’s most fascinating animals. For those who leave the meeting hungry for more excitement, the museum is open seven days a week at 202 San Felipe NW (except for major holidays, field trips and animal rescues). You can call (505) 242-6569 for hours and other information.
President’s Message Phew (picture wiping sweat off the brow) Phew, The Constitution and Bylaws are done. That is to say that your 2010 Board of Directors has finished revising the AGMC Constitution, Bylaws, and Guidelines to reflect how we do business nowadays. After becoming involved with the AGMC board and observing how we operated and then reading the bylaws, it was apparent that over the years the club operating mode had evolved but the bylaws hadn't, and as such, some of the things we were doing and how we were doing them were in violation of these documents. I started pushing to either change the bylaws or operate according to them. When I became president this year I asked the board if we could revise the bylaws and they agreed. We thought we were starting with the badly out of date 1995 version which was going to require a complete rewrite. What a job! Oh me, Oh my! But wait, it's not as dark as it seems; our past president (John D. Reinert) and historian (Dave Moats) found something interesting in the archives. Now a little history: The current official Constitution and Bylaws were filed with the state of New Mexico in 1995. Then, in 2001 the Bylaws Revision Committee revised the 1995 version, agreeing on the changes on April 4, 2001. These changes were incorporated into a "Final Draft Revision" document in December 2002. It is a mystery (to me) as to why there was such a delay between agreeing to the changes and creating the document. And it remains a mystery why the revised documents were never presented to the general membership for approval. It appears they were put aside and forgotten. But thanks to Dave, our fantastic historian, and the perseverance of John, this 2002 version was uncovered. And it reflected much more closely how we are doing business today, making the job much easier. So starting in February of this year, the Board has spent a portion of each meeting reviewing and revising the foundation documents of the AGMC. Sometime around July I was convinced that there was no way we would finish this year and the job would have to carry over to next year, so I agreed to continue as president to follow it through. Then in October the end was in sight; we held a special board meeting to finish the bylaws, and at the regular November meeting cleaned up a few details and declared it done. YAHOO!! The next step is to present these revised documents to the membership for approval (or not). You will be informed when they are posted on the club web site and you all can look them over for a few months and we will vote on them in March. I wish to thank the entire 2010 Board for their perseverance, patience & professionalism. This was one of those times when all the right people came together to do a first class job. Thank you. I would also like to thank Jim Winchell, who as president in 2001 appointed the Bylaws Revision Committee and the members of that committee: Tom Katonak, Tom Schmierer, Sally Estill and Jim Winchell, who spent their time back then which gave us such a head start in 2010. I have not met some of these people but I am sure the "oldtimers" in the club remember them. Now that this task is completed, there is no reason for me to continue on as president-------------------------------just kidding. Jay Penn 883-4195 el.chivo.viejo@earthlink.net
Minutes and Reports Albuquerque Gem and Mineral Club General Meeting New Mexico Museum of Natural History Sandia Room, 7:30 p.m., October 25, 2010 Call to Order President Jay Penn called the meeting to order at 7:30 p.m. Welcome Jay Penn welcomed seven newcomers to the meeting including Tim and Cindy Clair, Ken and Nancy Burton, and Wayne and Maxine Wilson. Jay mentioned that there were gem and mineral books as well as brochures available for purchase at the end of the meeting, among them is Geology of Public Lands and the Mineral Symposium brochure. John Reinert called for donations for the Symposium silent auction. Donation proceeds benefit the Symposium and gift shop. Nominating Committee Jay Penn reported the results of the nomination committee officer search. The following people were nominated for each position: President - Jay Penn Vice President for Programs - Jane Bardal was nominated from the floor. Vice-President of Field Trips - Brian Anderson has agreed to run again for the next year. Treasurer - Amy Penn agreed to be nominated from the floor. Secretary - Nanette Akin said she would like to be considered for the club secretary. Editor - Bill Barr volunteered to do the News Nuggets again. Membership Chair - There were no nominations from the floor.
Raffle Person - sells tickets at each general meeting and draws for the raffle to give out minerals. There were several people who volunteered to assist, including Barbara and Todd Brown. Jay mentioned that this is the slate for now. If a member cannot attend the meeting to cast their vote, they can contact the Club Secretary to cast their vote, prior to the November meeting, via email Carmeneliz505@Yahoo.com or phone 833-6064. Announcements The Las Cruces Club needs a speaker on meteorites. If any member knows of someone who would make a good speaker, contact Jay Penn with this information and he will pass it on to the Las Cruces club member. Field Trips Brian reported that 38 members, including some new ones, attended the trip to the Small Fry prospect. Members came home with fluorite, barite, and calcite. The Bondy family hosted a cookout for members, which was appreciated by all who attended. The November 20th field trip will be to the Blanchard mine outside of Socorro. Ray DeMark will lead this trip. Members will gather at the rock shop, drive to the parking area and consolidate into 4wheel drive or high profiles vehicles to go to the top. There will be no underground collecting. Ray will lead a tour of the Sunshine #3 mine and discuss te history, mineralogy and geology of the area. Registered attendees of the Symposium earlier in the month will be treated to a Thursday trip to Blanchard Mine. Membership Robair Lobato has name tags for those people who ordered theirs. Symposium Bill Barr announced that donations are needed for the Silent Auction. These donations can be given to John Reinert or Bill Barr. He also indicated that volunteers are needed to staff the tables. Proceeds from this go to the Mineral Museum. TOTE Show Paul Hlava discussed the Club’s annual mineral show. He requested volunteers to help with the show. Volunteers receive free admission and a parking pass for their work. Paul circulated postcards promoting the show to be held March 18-20, 2011. Refreshments Kathy thanked Pat and Todd Brown for bringing refreshments. She will have a sign-up for next year’s volunteers. AGMC Annual Holiday Dinner Jay Penn announced that the holiday dinner will be December 11th. We need for volunteers to show up at 3 p.m. to set up the room, including setting up tables, chairs, decorations and food. The plan is to eat at 5:00 p.m., have the silent auction, install new officers, present scholarships and clean up by 9:00 p.m.. AGMC supplies the meat and drinks. Club members bring potluck dishes to go with the BBQ/ham, and eating implements and napkins. No alcohol is permitted in the church. Speaker - Nelia Dunbar Bruce Owens introduced Nelia Dunbar, geochemist and volcanologist. She presented an exciting program about the volcanoes of Antarctica. She was part of a team that researched and mapped volcanoes, icebergs, lava lakes and ice caves. It was a very interesting evening filled with beautiful pictures of various volcanoes and the challenges of being in a sub-zero environment, both on the human body, and also on the equipment used to measure and track volcanic activity. The research team’s activities were filmed for a documentary called “Frozen Planet”. It promises to be an outstanding, not-to-be-missed program. Be sure to tune in. Respectfully submitted, Carmen Taylor, AGMC Secretary ______________________________________ AGMC Junior Club Report There were 23 AGMC Jr. Club Rock Retrievers at our October 25th meeting, with 5 new members joining! Congratulations to our newest Rockhound, Max Blankley! Max has earned 6 merit badges and has graduated to the official status of “Rockhound”, a mark of accomplishment and distinction! We began the meeting with the awarding of our latest merit badges for “Gold Panning and Prospecting”. Then we started our next activity: Earth in Space. We began with an exercise of modeling the solar system. Earlene brought a model of the solar system, which included the eight planets (poor Pluto). We watched as the planets orbited the sun and as Jupiter kept jumping off and rolling all over the table. Jim then escorted the kid/planets out across the room, then out through the door and across the other room, spacing the kid/planets relative to the sun. We included Pluto. The class decided that the scientists must be wrong and we’re defending Pluto’s right to be a part of the system! Next, we discussed visitors from space: “cosmic debris” in the form of meteors, asteroids and the asteroid belt, tektites and comets. Finally, Jim passed out little packets of “gutter dust” that he had collected from the eaves of his house, along with magnetized needles and instructions for the kids to take home as an experiment. The kids are to roll the needle in the dust and watch the tiny spherical meteorite dust stick to the needle. The kids could then look at the tiny meteorites under a microscope or magnifying glass. We concluded the meeting with a little discussion about our upcoming Jr. Club field trips – one to collect unusual golden-orange/yellow fluorite; another field trip to make lapidary projects using crystals that we have found and have a Christmas party, too. See you at the next meeting! Earlene and Jim Announcements Warning, Warning #1\ There are 5 Mondays in November; the general meeting is the 4th Monday of each month. See ya the 22nd. ______________________________________ Dues are Due (well, soon anyway) All memberships expire Dec. 31. Dues are still only $20 per household for 2011. The membership form is on page 13 of this issue as well as on our web site. You can print a copy and fill it out ahead of time to renew at the general meeting or mail it to: AGMC, PO Box 13718, Albuquerque NM 87192-3718.

Amy Penn ______________________________________ Warning, Warning #2 This is the last News Nuggets for 2010. We don't publish in December, nor do we have a standard general meeting or a field trip. What we do have is our annual… Holiday Party, Pot Luck Dinner, and More! This big event is cleverly scheduled almost exactly halfway between Thanksgiving and Christmas on December 11th, so we get three big feeds in a period of a month. Yahoo, I like food. See the "AGMC Upcoming Events" section below for details. Upcoming Club Events
AGMC Holiday Event, December 11, 2010 Setup 3:00 p.m.; Start eating 5:00 p.m. Heights Cumberland Presbyterian Church Gym, 8600 Academy Rd NE It is always a fabulous evening so get the date on your calendar and plan to join. Both Cindy and I will be attending family graduation events and unable to be present. We will help in the planning and details but we really need your assistance. We have a new location and a new time of day. The club provides the meat, drinks and some desserts. Members provide side dishes of all kinds to go with BBQ & ham plus their own table service. We are at a church, which has a strict no alcohol policy. We have a white elephant silent auction and it helps subsidize our event. We anticipate a great crowd while we install new officers and honor our scholarship recipients. Be there... Hugs, Gwen Poe Here are some more details: Every year the December general meeting is a potluck dinner with a silent auction. The club provides the main course (usually barbecue and a ham), dessert, drinks anddecorations. The membership brings a potluck dish to share, your own table settings and a white elephant for the silent auction. This can be anything (doesn't have to be a mineral or lapidary related item). This is how we rent the hall, buy the food, etc. Special needs: help to make calls, do decorations, staff the auction and set up for the evening.† Please join in the preparations. Call Jay Penn to offer a helping hand, 883-4195. We have the room (gym) from 3-9 p.m. We must†set up†and take down the tables and chairs and completely clean up after ourselves and be out by 9:00 p.m. This is a tight time frame, so let’s try and stick to the following schedule. Start setting up 3:00 Start serving food 5:00 Scholarship presentation 6:30 Install 2011 officers 7:00 Silent Auction ends 7:30 Pay for what you won 7:30 Start cleanup 8:00 Out by 9:00 The church contract specifies that: No alcoholic beverages or drugs allowed (there will be church members present to keep an eye on things). Children must be supervised at all times. We can only use the restrooms in the gym. Jay Penn 883-4195 November Field Trip Preview Saturday, November 20, Blanchard Mine The field trip to the Blanchard Mine has been rescheduled for Saturday, Nov. 20. We will meet at 9:00 a.m. on the road adjacent to the rock shop in Bingham and proceed as a group to the mine. There will no collecting underground but I will give a tour of the Sunshine #3 adit to those who have not had an opportunity to see the underground workings. Those going underground will need a hard hat and lighting. Ray DeMark
October Field Trip Report Small Fry Prospect The October AGMC member field trip began under chilly gray skies at the little pizzeria at US-84 and NM-554 east of Abiquiu. More and more folks came rolling in and soon we caravanned the four miles up the road to the Small Fry Prospect. Jesse Kline informed the group about the geology of the area and gave some excellent tips on where to find the purple, pink and even iridescent botryoidal fluorite, calcite and barite scattered throughout the canyon and up the hills. A total of 38 enthusiastic AGMC members enjoyed some great collecting. Big thanks to club members Brian & Carol Bondy for hosting all us dusty and hungry rockhounds at their post-collecting BBQ. Brian Anderson January Field Trip Preview Baker Ranch Mark your calendars for Saturday, January 15. Michael and Janey Johnson will lead a field trip to the Basin Range Volcanics Geolapidary Museum and then onto New Mexico's bootheel and the Baker Ranch Mine south of Deming. We'll collect some of those agate thundereggs that were highlighted at the AGMC General Meeting last June. Possible visit to Deming’s Luna Mimbres Museum. More details to come. Brian Anderson 2011 Field Trip Note The 2011 Field Trip Schedule is included on page 12 of this issue of News Nuggets.
A Long Long Time Ago in AGMC November 1975 News Nuggets VOCANOES ERUPTING SOON IN THE RIO GRANDE VALLEY??? By Pete Modreski Not necessarily, but a geophysicist at New Mexico Tech says there is evidence that molten rock exists beneath the surface in the vicinity of Socorro. Dr. A. R. Sanford has been studying the seismic waves produced by micro earthquakes. These waves reflect off deep layers of rock and provide information about the rocks at depth. Dr. Sanford’s data indicates that a body of molten rock is present some 18 km (18 km equals 11 miles equals 59,000 feet) below the surface and that the layer extends for some 50 km (31 miles) along the Rio Grande valley near Socorro. His observations were reported at a conference on “Geology of the Rio Grande Graben” held in August 1974 in Santa Fe. The conference was described in the August 1975 issue of Geology magazine. There is other evidence that hot rock exists beneath the surface in the valley. The increase of temperature with depth, as can be measured in drill holes, is higher than normal; this is known as a “positive heat-flow anomaly”. In fact, it is said that on one hillside near Socorro snow never stays on the ground long, and always melts much faster than in the surrounding area. How did the molten rock get there and what will happen to it? Presumably this “magma” moved upward along some fracture zone from a much greater depth (perhaps 100 miles or so). Most likely the molten rock will simply stay where it is and slowly cool and crystallize to form a “sill” of igneous rock. However, it is certainly possible that earth movements might open up additional fracture zones along which some of the magma could move closer to the surface and even create a volcanic eruption. The valley of the Rio Grande is what is known as a “rift valley” or “graben” – a huge zone of weakness in the earth’s crust. Many fault zones (such as those responsible for the uplift of the Sandia Mountains) lie within the valley, and it has been the location of numerous volcanic eruptions in the (geologically) recent past. The basalt lavas on the west mesa near Albuquerque are now believed to be about 190,000 years old. It is almost inevitable that, with time, more lava eruptions will take place in the Rio Grande rift. In fact, the valley near Albuquerque may some day end up the way it is near Taos – completely filled by lava flows to depths of several hundred feet, with the river cutting a narrow gorge through the basalt. November 1976 News Nuggets Article Explains Geologic Activity Near Socorro By Mark Blazck An article entitled “Modern Uplift Associated with a Proposed Magma Body in the Vicinity of Socorro, New Mexico” by Robert Reilinger and Jack Oliver (both from the Department of Geological Sciences, Cornell University) was published in the October issue of Geology. The article offers support for past research which indicates that “…a zone of low rigidity, in essence a magma body, exists in the crust beneath the Socorro area of the Rio Grande rift.” In this article the authors state, “Analysis of repeated leveling in and near a part of the Rio Grande rift in New Mexico reveals a zone of anomalous relative uplift in the vicinity of Socorro.” The authors go on to explain that “Data in the Socorro area of the Rio Grande rift indicate rather striking rates of relative uplifts and tilts, which, on the basis of their location and spatial pattern, appear to be associated with the proposed magma body. In explaining these uplifts and tilts, Reilinger and Oliver state “…these movements could result from expansion of the proposed magma body. This new information presented here provides additional support for a magma body of considerable extent in the Socorro area.” What good is all this information? The authors explain: “The topic seems important not only because of geothermal energy potential, but also because of the fundamental importance of intrusion in the evolution of continental crust!” Compiled, selected and annotated by Dave Moats, AGMC Historian Classified Section For sale: a MSA miner’s cap lamp and charger.

Mystery Mineral For September, 2010 From the devious mind of Paul Hlava A few folks emailed me that they read the Mystery Mineral and try to decipher the mineral names. Email me at paulhlava@q.com and let me know your guesses by copying the Questions below and answering them. This includes AGMC members and everyone else who reads ”News Nuggets”. I have gotten very few responses, folks. EMAIL me at paulhlava@q.com! I have been gratified by folks responding that they WORK at these minerals. Good, that IS the idea. This way you learn about them. The Game Plan – I will describe a mineral and you have to guess/decipher/research the name of the mineral and the answers to the other questions asked about uses, history, notable facts, etc. I expect the Top Guns in the club to be able to guess the name off the top of their heads. The learners will need a reference book or two. You will benefit most if you do not ask others for the answers but work it out for yourselves. When you have decided on the name you can compare notes with others or wait for the answers to be announced at the meetings or published in the News Nuggets. Good luck and have fun. Last year I discussed minerals with metallic and sub-metallic lusters. This year I’ll work on minerals found in the Hansonburg District of NM. This month’s MM is a hydroxide-halide-sulfate of 2 metals. It is a rare, secondary mineral. The trigonal crystals are hemimorphic (the top and bottom have different shapes - like tourmaline) and have a perfect basal cleavage and (3) distinct pyramidal cleavages. It is transparent to translucent with a vitreous luster. It is dark to emerald-green, or blue-green. Sp. Gr. = 3.14, H = 3.
Questions What is the name of the mineral? What is the origin of the name? What metals does it contain? What non-metals does it contain? What other minerals might occur with it? What is it mined and used for? Do you have some in your collection? List some famous localities In NM – In the USA – In the World – Answers to Last Month’s MM What is the name of the mineral? Murdochite What is the origin of the name? After Professor Joseph Murdoch (1890–1973), American mineralogist, University of California, Los Angeles, California, USA. What metals does it contain? Copper (Cu) and lead (Pb) What non-metals does it contain? Oxygen (O) and maybe chlorine (Cl) and/or bromine (Br). What other minerals might occur with it? Other secondary minerals of Cu and Pb. What is it mined and used for? It is quite rare and so it is only mined by association with other minerals or by mineral collectors. Do you have some in your collection? Yes List some famous localities In NM – Hansonburg District In the USA – AZ, CA, NV In the World – Australia, Chile, Greece, Iran, and Mexico It looks like NM and AZ have more localities than the rest of the world combined!
