GENERAL MEETING FEATURED PRESENTATION
"Taking Earth’s Pulse and Temperature Using Seismology: Roaring Oceans and Singing Icebergs" by Dr. Rick Aster
The worldwide network of seismographs designed to detect earthquakes is also recording aspects of Earth’s climate. Buried in the background of these continuous seismic recordings, even in the deep interiors of continents, are "microseisms" -- seismic waves created by ocean waves pounding the coast and interacting with the sea floor. From over 35 years of high-quality continuous global seismic recordings, my colleagues and I have been able to reconstruct a unique record reflecting past patterns of ocean-storm intensity. This work includes evidence suggesting that violent ocean storms across the planet, and associated ocean waves, have been increasing in their frequency of occurrence during the past three decades. Seismometers sited on the great ice sheets and icebergs of Antarctica are also revealing signals due to waves from extreme ocean storms and from regional iceberg calving. Hours-long collisions between Earth’s largest icebergs as they gyrate under the influence of coastal currents also cause the icebergs to "sing" with a newly discovered type of seismic and ocean acoustic tremor. Extreme storms occurring during the Arctic winter produce waves that propagate to Antarctica. One resulting hypothesis arising from seismic studies conducted atop giant icebergs is anecdotally supported by the breakup of Earth’s largest iceberg in late 2005. It seems that these waves can influence iceberg behavior in the Antarctic because they arrive during what is summer in the southern hemisphere, when large tabular icebergs and ice shelves are largely unprotected by sea ice and are thus susceptible to calving and breakup. Seismic investigations in polar regions will doubtless continue to reveal still more about these and other novel dynamic processes affecting Earth’s largest glacier systems and to illuminate previously unsuspected linkages between climate, oceanography, seismology, and glaciology.
From the President
Well, the State Fair is over. The Balloon Fiesta has flown by and the Goblin parade is coming! The 30th Annual New Mexico Mineral Symposium (in which our Ray DeMark is the Featured Speaker) is about a month away. From my point of view, this year has gone sorta fast. There have been some bad but mostly good times. We have lost quite a few members to another world. We have lost another member, Ellen Cosper of Peralta passed away after a long illness on September 30, 2009. She leaves behind her husband John M. Cosper: Father, Richard McQuire; daughters, Tawnya Cosper; Keylee J. Cosper; and sisters; Kathie McQuire and husband John Broom, and Rikki Gavalyas and husband Wayne. She loved the outdoors, animals and was a member of the AGMC. She was an avid rock hounder. Our condolences go out to the family. Back to the good times. We've welcomed many new members to our club; had fun and successful field trips. We have two more field trips and the Christmas party to go! I feel that the main purpose of our club is to make new friends and to learn the many "Facets" of Rock hounding; and last but not least, to have fun. Our Junior club has been a source of pride to me due to our teachers; Erlene Shroyer, Jim Hill and the parents whom became juniors to learn with their children. WAY TO GO! Many of you may not know that our club is one of the sponsors of the symposium. We also are in charge of the silent auction. We need your help. We need donations of quality specimens for our table. The proceeds go to New Mexico Tech Museum. See you at our next meeting on October 26, 2009.

Minutes and Reports
Field Trip Report Saturday, September 19 Zuni Mountains – Mirabal mine
About 25 members attended the field trip in the Zuni Mountains. We collected barite and fluorite in the morning, and after lunch went to the copper mine. People found many nice specimens of tree copper, which is petrified wood replaced by copper, mainly malachite. The weather was very pleasant. A few storm clouds threatened around noon, but they soon dissipated. The next day a windbreaker was found with some rocks in it, so if you lost it, let me know. Jane Bardal Jr. Club Meeting Report September 28, 2009
Our September Jr. Club meeting was attended by eleven Jr. Members. The meeting was a continuation of the August meeting which was a review of the Mineral Identification Test kit. We learned how keep a journal of our collections, how to label a specimen by placing a dab of white-out in an inconspicuous spot that won’t show if the specimen is exhibited, and writing a number on it in black marker. We then made a journal entry for each specimen which included the specimen number, the name of the specimen, and location where it was found. Next, we began working on our next merit badge: "Stone Age Tools and Arts". For the first activity, we saw examples of rocks and minerals that have been used by indigenous cultures around the world in crafting tools or making artworks. Some of the examples were obsidian (arrowheads, spear points, scrapers, and knives), agate and jasper (also used for spear points and arrowheads), granite (heavy and coarse, and thus good as a grinding stone or for making tomahawk or club heads), basalt (grinding stone), hematite, azurite and malachite (used to make red, blue, and green paint). We then planned a field trip to the Petroglyph National Monument to complete the second activity: recording and interpreting rock art. Finally, the mystery mineral was passed out to the class, and their assignment for the October meeting is to identify the white splotches in the black obsidian. If you would like more information about the AFMS and their merit badge program, visit their website at www.amfed.org.

General Meeting Minutes September 28, 2009
President John Reinert called the meeting to order at 7:30 p.m. and welcomed new members and guests. John thanked everyone who helped set up, tear down and man the table at the State Fair. He also reminded us that the symposium is coming up in November in Socorro. The Nominating Committee was introduced: Mike Potts, Kathy Lawicki, Gwen Poe, Jan Burrows and Bob Burrows. They need to present a slate of nominees to the current board for the upcoming election of 2010 board members within the next week. Amy Penn announced that T-shirts from the TOTE show are now available for $11. Brian Anderson said that the field trip to the Zuni Mountains led by Jane Bardal was successful. Members collected fluorite, barite, amethyst and copper specimens. Paul Hlava will lead a tour of the Turquoise Trail in October. Jim Hill and Earlene Shroyer said that 11 kids were at the juniors’ meeting this evening. They talked about finishing up a unit on their test kits and journals. Earlene also spoke about Stone Age art and tools and is working on arranging a field trip to Petroglyph Park in the near future. They are working on the merit badge in the Native American unit. Michael Johnson said that new member packets will be available at the October meeting for those who didn’t get them tonight. Also, if anyone wants to order a name tag, please see him. Paul Hlava spoke about the status of the Treasures of the Earth [TOTE] show in April 2010. Paul also introduced himself as the speaker tonight. He gave a colorful presentation on "The Materials Known as Gem Stones." The meeting adjourned at 8:45 p.m. for refreshments and door prizes.

Junior Club Field Trip Report Saturday, October 10 Petroglyph National Monument
On Saturday October 10 at 2:00 p.m. the Junior Rockhounds met at Petroglyph National Monument for the purpose of viewing and sketching the petroglyphs found on the basalt boulders. We had 12 juniors and their parents attending, the weather was perfect and everyone made sketches for use at the next meeting. I saw lots of great sketch pages and we talked about what some of the petroglyphs are supposed to represent. We also learned the site is still used by Pueblo people for ceremonies. We hiked the Macaw trail and the Loop trail and finished about 3:15 p.m. Everyone was excited and we had a great hike.

Treasures of the Earth - 2010 Show Report
Howdy Folks. Just before September, I sent out the first round of contracts to the dealers from last year who said they wanted to return. I have gotten responses back from all of them. A few of them will not be back and several others have been slow to pay because of the rotten economy. The response deadline for the first round of offers was October 1st and I still have a few that need to send in their stuff (yeah, I’m a soft touch). Some folks have upsized and new folks have stepped up so I have only 5 tables and one full booth left open. I’m checking with folks on my back-up list then I’ll beat the bushes to fill the spots. As usual, I will probably get a couple of dozen outfits trying to get into the show between now and show time. One of the touchstones of a good show is how well our dealers did last year. And as I mentioned before, ours did from FANTASTIC! to dismal. Most of the dealers did well or better. I guess the word is getting around that the Treasures of the Earth show is a good one because I’ve had new dealers asking for space from coast to coast. (Everyone who helped at the show this year should now pat yourselves on the back for putting on such a fine show.) Publicity for the show is underway. Doug St. Pierre has contacted a list of mineral and gem magazines that have show calendars so you should see these notices soon. Of course, we will soon have thousands of GARISH (on purpose) yellow flyers for everyone to hand out. Postcard designing is in progress and should be available before the holidays. Newspaper and other ads will be done right before the show. Once again I will plead for more people to get involved with the show committee. Apropos of that, I plan to have sign up sheets at the January meeting for a number of jobs to be handled. These include set-up, tear-down, and overnight security. Other people will need help: admissions (Kimberly Richie), raffle and door prizes (Hank Miller), silent auction (Bill Barr), displays (Mike Sanders), etc. (If it is a silent auction why is it so noisy over there?)

AGMC This Month
Saturday, October 24th General Geology Field Trip Turquoise Trail - East Sandia Mountains 8:30 a.m.
In preparation for the Oct. 24th field trip along the turquoise trail, I have sent a road log and geologic column to the NN editor so folks can make a hard copy and get acclimated with what we plan to see and do (see the Miscellanous Section). A general description was published in last month’s NN. The next paragraph is a repeat of the basic instructions from that article. We will meet at the Einstein’s Bagels/Starbucks area of Four Hills Shopping Center and plan to leave there at 9:00 AM. Take it easy on the coffee as there are few, if any, potty stops. It would be nice to car pool as some of the stops have limited parking. Besides, you can visit more. Bring reasonable clothing for the weather: we won’t be doing any clambering over rocks so casual street clothes are OK. You can even wear normal shoes. Water and light snacks will get you through the day. The trip will end about 2 to 3 PM. If the weather is bad, we will try on Oct. 31. Questions? hpf1@qwest.net or 255-5478 Paul Llava _____________________________________
Monday, September 28th Junior Club Meeting Natural History Museum Annex 6:30 p.m.
At the October Junior Club meeting we will make our own petroglyph using the sketches we made at the field trip to Petroglyph National Monument. Please bring your sketches and a section of a newspaper (4 or 5 sheets for padding on the table). Earlene and I will show you how petroglyphs were made. Earlene and Jim

Friday - Sunday, November 13 - 15 Mineral Symposium and Tailgate Socorro, NM
This whole affair actually begins on Friday evening with an informal pre-symposium social and "tailgating" session at the Comfort Inn and Super 8 Motels with attendees spreading out their inventory in their motel rooms for anyone who wants to drop by to see and/or buy their mineral specimens. This is a social affair especially as you get to know more and more people associated with the "rock" hobby. Most of these rooms will be open until 10:00pm or later and most will also be open on Saturday evening. Saturday morning kicks off the 30th annual New Mexico Mineral Symposium which is a day and a half of talks about mineral occurrences most of which are in the Southwest. It is held on the NM Tech campus in Socorro, NM. This year there will be 16 talks including "Specimen Cleaning, Trimming, and Preparation 101", "The Marvelous Agates of Luna Co., NM", as well as several about mineralization of various areas of the southwest, and a few on mining history. And new this year, the Mining Artifact Collectors Association (MACA) folks are presenting 4 talks. The talks are 30 minutes long with a break after every two talks. AGMC member Ray DeMark is the featured speaker this year, so come out and support him. For more information on the talks, a map, and registration fees go to www.geoinfo.nmt.edu, then look under Mineral Museum, then NM Mineral Symposium. At the bottom of the page you will find the current symposium brochure (which has the detailed schedule of events, map, and registration form). Pre-registration is convient but you can register and pay at the door. I will testify that this is worth way more than the registration fee in knowledge gained and acquaintances met. The NM Tech students provide a continental breakfast in the morning before the talks and refreshments during the breaks on both days. You are on your own for lunch, 12:00 - 1:00. The schedule allows you to tour the NM Tech Museum from 1:00 - 2:00 Sat., it is spectacular, don't pass it up. The museum also offers mineral specimens for sale at very affordable prices. Saturday night there is a dinner ($20/person, pre-register strongly advised, seating is limited) and mineral auction to benefit the symposium. To wind down the weekend, after lunch on Sunday (1:15 - 3:00) there is an AGMC hosted silent auction to benefit the Mineral Museum. There is no charge to attend the auction. If you wish to sell, the tables cost $20 each, sign up at the breaks during the symposium or just before the auction. We ask club members for mineral donations to put on the club table. You can bring those items to the sign up table during the symposium or get them to a board member by Nov 11. There are plenty of motels in Socorro (see symposium brochure) but some people prefer to commute each day as it is just over an hour drive each way from Albuquerque.

Saturday, November 24th Field Trip Blanchard Mine - Bingham, NM 10:00 a.m.
The annual field trip to the Blanchard mine will be on the Saturday after Thanksgiving this year. We will meet at 10:00 AM, adjacent to the rock shop in Bingham, and proceed as a group to the pad at the base of the mine. Passenger cars can make it to the pad but high clearance and/or 4-wheel drive will be required to make it up the hill to the mine. Safety is paramount and long-sleeved shirts, pants, boots and safety glasses are recommended, particularly for children. Children must be closely supervised due to the inherent dangers of mining areas. There are no facilities or water at the mine, so be forewarned. Due to increasing concern over liability, there will be no underground collecting this year. I will however, give an underground tour of the Sunshine #3 adit for those that have not previously been underground (hard hat and lights required). You will need hard rock mining tools (hammers, chisels, etc.) to collect at the Blanchard mine. Beautiful specimens of fluorite, galena and barite are readily collectable and uncommon minerals such as linarite, brochantite, wulfenite, cerussite and many other rare minerals can also be found. Be sure to bring a hand lens to look for fascinating micro minerals. See you at Bingham on the 28th of November. Ray DeMark
Miscellaneous Check out Nov 2 & 9 in the "Upcoming Events in the Southwest" section for a "Rocks and Minerals" class at the Natural History Museum. Thank you Shannon Wagers for bringing this to my attention.
A Long Long Time Ago in AGMC 26 Oct 1959 newsletter - "MINERALS OF NEW MEXICO" by Stuart A. Northrop. The first edition of Dr. Northrop’s book was published in 1942 and reprinted in 1944. The new and revised edition, about to be published by the University of New Mexico press, contains 681 pages and describes many new minerals including those resulting from the intensive search for uranium. Stuart A. Northrop is Professor of Geology, Chairman of the Department, and Curator of the Geology Museum at the University of New Mexico. A resident of Albuquerque since 1928, Dr. Northrop became head of the UNM Geology Department in 1929, and in 1937 established its Geology Museum. Since 1941 he has served as collaborator in seismology for the U.S. Coast and Geodetic Survey, and since 1943 he has been geologist for the Fuels Branch of the U.S. Geological Survey. Born in Danbury, Connecticut, in 1904, Stuart A. Northrop was an undergraduate at Robert College, Constantinople, and Yale University where he received his B.S. in 1925 and Ph.D. in 1929. He is a member of the Paleontological Society, the Seismological Society of America, the American Association of Petroleum Geologists and Sigma Xl. A fellow of the Geological Society of America, Dr. Northrop was chairman of its Rocky Mountain Section in 1955-56. He was president of the New Mexico Geological Society in 1949-50.

Arsenides, sulfides, and arsenic-sulfides of cobalt, nickel, and iron, plus gangue minerals like calcite and other carbonates), quartz, feldspars, and oxidations products like erythrite (cobalt bloom), annabergite What other minerals might these two easily be confused with? Cobaltite, ullmanite, gersdorffite, etc. What is it mined and used for? Cobalt metal and glass making, the nickel and arsenic can also be recovered. What is the metal used for? Ferrous alloys, pigments, radioactive Co-60 has medical and other uses. What is the semi-metal used for? Bronzing, pyrotechnics, lead alloys, electronics. Do you have some in your collection? Yes. List some famous localities In NM – Alhambra (or Blue Bell) Mine, Black Hawk District, Grant Co. along with nickelskutterudite In the USA – lots of localities but none remarkable In the World – Cobalt, Ontario; Czech Republic; France; Germany; Italy, Morocco, Slovakia; Spain 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. 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 Email me at hpf5@qwest.net and let me know your guesses by copying the questions below and answering them. I have gotten very few responses, folks. EMAIL me! I have been gratified by folks responding that they WORK at these minerals. Good, that IS the idea. This way you learn about them. Good luck and have fun. Last year I discussed minerals and rocks that are used as gemstones. This year I think I’ll work on minerals with metallic and sub-metallic lusters. This month’s MM is a less common mineral formed in low temperature veins or contact metamorphosed ore deposits. It can be found as coarse sized crystals (monoclinic). It is often massive or granular and sometimes colliform. It can also occur in fibrous to feathery form. It exhibits good prismatic cleavage. It is opaque with a metallic, submetallic, to dull luster, the color is black, grayish black to silvery gray. It has a black streak. Sp. Gr. = 4.7to 5, H = 4 - 6. Questions: What is the name of the mineral? What is the origin of the name? What nicknames were given to the hairy types from NM? What metals does it contain? What non-metal does it contain? What other minerals might occur with it? What other minerals might it easily be confused with? What is it mined and used for? What is the metal used for? Do you have some in your collection? List some famous localities In NM – In the USA – In the World – Paul Hlava October 11, 2009
