President's Message
It's late Monday night, March 13th and we're in the home stretch the week of our annual club show. Treasures of the Earth 2006 begins at 10:00 AM on March 17, 2006. Despite some last minute problems I am confident we will have another good show this year. I want to thank everyone in advance for volunteering your time and efforts towards making our show a success. It's good to see new people and long time members all stepping forward and asking "how can I help?" I am always amazed at how generous you folks are with your time when we need you the most. Thanks!
Julie and I headed down to the Deming show around noon last Friday. We knew it was supposed to be windy, but we never thought it would be that windy. Nogal Canyon north of T or C was like a wind tunnel and the cutoff from Hatch to Deming was only better because we were heading straight into the wind.
We went to the silent auction at 7:00 PM on Friday night. There were about 30 tables, maybe 200 people, and lots of interesting specimens, stones, and cutting rough. The Deming auctions support different community needs such as feeding and providing blankets to the homeless or to stranded travelers.
The auction night not to miss is the live auction at 7:00 PM on Saturday night. It was very cold that night and attendance was kind of light compared to other years we've been there. There were maybe 100 hardy souls that cold windy night where normally 200+ would be there. For whatever reason, prices were lower than I expected for most items and we were back in our motel room with our stash of new specimens by 10:00 PM (as if we needed more rocks).
We returned to the show around 11:00 AM on Sunday just to see if we could find any bargains. Most of the tailgaters had already closed down or were closing down and leaving early. Not only was the wind as bad as it had been on Friday and Saturday, but it was freezing cold as well. We decided it was time to get the heck out of Dodge!
The drive back was worse than the drive down on Friday morning. It felt like we were on a reality simulation ride but it was very, very real. We were tossed around I-25 for the entire three hours till we got back to the North Valley. Whew!! Home sweet home!
See you on Thursday.

March Field Trip
This month the focus of the field trip will be fossils! There are two possible destinations for our trip. The first choice is the Kinney Clay pit, in the Manzano Mts. This is a shallow Pennsylvanian age deposit. This locality has plant remains, fish, and other fossils. Hopefully we will be able to secure permission to visit and collect there.
The field trip will take place on the 1st of April. That should be a lot of fun!
The other possible destination is the Escondida fossil beds, just north of Soccoro, New Mexico. This locality is a fossiliferous limestone of the Pennsylvanian age. The fossils found here include brachiopods, horn corals, crinoids are some of what we can expect to collect. The fossils here are highly silicified and are quite interesting.
Jeff and I will have a firm decision by the next club meeting (March 27th) and will have directions, times, etc., at the next meeting.
Hope to see you there, Ron Boyd

February Meeting Minutes
President Orlando Garcia could barely be heard above the loudly socializing crowd to call the February club meeting to order at 7:40. He opened with announcements about ailing club members Herb Traulsen, Russell Sperling and Rosemary Miller, and noted that get-well cards would be circulating during the meeting. We wish the best to these folks who need our thoughts and prayers, so send healing energy out to them at this time. Orlando welcomed 13 new members/guests and got the news that potentially a whole middle school would be attending the TOTE Show. Yikes! Refunds are due to a couple of people who've paid dues twice. And a reminder that the mailing label of the News Nuggets will reflect the status of your membership, 05 and you owe 06 and you're good to go. Ron Boyd announced the details of the next field trip. We're to meet at 10:30 at the graveyard in Puerto de Luna to look for aragonite. Surface collecting so no special equipment will be needed. The nearest town and services is located in Santa Rosa; that's about two and a half hours drive from Albuquerque. Show Chairman Paul Hlava relayed that the full complement of dealers is aboard for the upcoming TOTE Show. The sign up for show staffing was successful (the overnight security detail needs more help; call if you can help). Flyers are available; take some to distribute. Help is needed in addressing the postcards. Gwen Poe polled the crowd to choose the entre that we provide for the Thursday potluck. No surprise it's BBQ again. The club provides bread, dessert, coffee and lemonade, but all attendees are asked to bring a side dish to share in addition to your own place (knife, fork, spoon, plate, cup). Shell need cashier/staff help with the evening's silent auction; so let her know you can help. This year there will be prize categories, winners in three categories will be announced towards the close of the festivities. Awards will go to the big spender at the silent auction, the most unusual donated silent auction item, and the most field trips attended. This should ratchet up the fun for what is already renowned among the dealers as being a high quality affair. Dont miss it! Charlotte Cooper requested staffing help at the Junior Club table during the show. A sign up sheet was passed around. Charlotte and Karen Peterson are accepting donated material for the Junior table, call them; they will pick up. They are going to need help unloading the material on Thursday at the show site. See if you can stop by for a few minutes to help, the bad backs will appreciate any small amount of time you can spare. Can any one help Orlando bag giveaways? The labels are already done. See Dave Moats to help with handing out door prize tickets at the door and with the awarding process.
Orlando then introduced the evenings' speaker, Joe Dan Lowry. Joe Dan is the proprietor of the Turquoise Museum in the Old Town area. His familial background includes the Zachary's, an uncle who was a mineralogist, a father who wrote law, an affable grandfather that managed to amass a voluminous and venerable collection. Joe Dan himself is a knowledgeable and funny guy. With humor and authority he described the quirky history and evaluation criteria for this ever-popular gemstone. He brought lots of samples and encouraged hands on interaction with it after the talk. He began by describing the mineralogical properties of turquoise. This hydrous copper aluminum phosphate solidifies in any fractured rock initially as 'chuck', white chuck. Color develops over time, with copper giving a bluish cast and iron greenish. Deeper color development is more desirable, as is distinctive and attractive matrix. Deep color takes a lot of time and the right ingredients and is thus more rare. And we all know how rarity translates in the market place! Matrix color comes from the host rock. Variously described as laced, eggshell, and spider web, the matrix quality can make an industry icon. Between 60 and 80% of value is determined by the actual mine source. Some icons and famous localities are: Lander Blue, the #8, Blue Jim, Lone Mtn. and Bisbee. Today, China mines contribute 80% of the global market production rated at 40-60 tons annually. In the USA, Nevada produces the most. When buying turquoise, it behooves the buyer to familiarize oneself with the terminology associated with the industry. Most turquoise is 'stabilized' nowadays. That means that it has been pressure impregnated with resin, as it can be quite soft in the original state. Federal and state laws dictate that 'natural' means gemstone, not 'genuine' or 'real'. When asked about backed material he replied that anything under 1/8th of an inch is routinely treated thusly and shouldn't affect value. He also explained that color change is not necessarily bad. The innate porosity of the gemstones can be enhanced by patina associated to living with and wearing the stones. Indeed the color potential is specific to the mine and can be luminous. With the patina comes the lore and magic spell turquoise has had on humans for millennia. I daresay Joe Dan has enjoyed the rich cast of characters he's encountered during a long rich association with turquoise in New Mexico's history. Thanks for sharing the fun and inside info on this important mineral Joe Dan, and thanks for the door prize additions.
I confess and apologize that I neglected to find out who brought the goodies, though I did enjoy some. Thank you whoever you are!
Door prize winners = 600+ No change in my personal record.
Do you really know what is happening beneath your feet?
Hot springs, natural groundwater quality, and fluorite deposits in the southern Rio Grande rift.
Virgil W. Lueth
March Guest Speaker
The Rio Grande Rift is a large north-south trending geologic structure that splits New Mexico in half. It began pulling apart approximately 30 million years ago and continues to this day. The extension of the rift is responsible for the concentration of small earthquakes in New Mexico and serves as a conduit for magmas formed deep in the EarthÕs mantle. This concentration of geologic (also known as tectonic) activity has helped shape the modern landscape of New Mexico. In addition to the surface expressions of the rift as mountains and deep valleys, magmatism and deep circulation of water is modifying the geology and hydrology of the subsurface.
This presentation is a summary of recent work published in the scientific journal, Chemical Geology, with coauthors Robert Rye (United States Geological Survey) and Lisa Peters (New Mexico Geochronological Research Center). The study documents specific features of fluorite deposits found at the surface that reflect the geological processes occurring deeper in the crust. These features are mainly tied to the occurrence of a mineral called jarosite that forms by a unique process in these deposits. Normally jarosite forms from the weathering of the mineral pyrite but in these deposits hydrogen sulfide (sour gas) migrates up rift faults and then mixes with oxygenated water to form sulfuric acid and jarosite. Jarosite is composed of potassium (K), iron (Fe), sulfur (S), oxygen (O) and hydroxide (OH) with the chemical formula: KFe3(SO4)2(OH)6. This unique composition allows for the dating of the mineral by Ar-dating of the potassium and by use of stable isotopes we can identify of the source of sulfur, oxygen, and water.
The results of this research have found that these deposits have formed in the rift over the last 10 million years and are still forming today. The chemistry of many hot springs along the rift is identical to the fluids that caused the fluorite mineralization in the past. Accordingly, the circulation of deep fluids often influences water quality along the rift by addition of components often not desired in drinking water.

Mystery Mineral
March, 2006
From the devious mind of Paul Hlava
The Game Plan Ð 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 that are named for geographic localities. This year I thought I'd concentrate on minerals named for their chemistry. And this second one is maybe even easier than last month's.
OK. This month I'm going to stray from compositional names and go to a thematic name.
This mineral is a simple sulfide of a less common metal, hexagonal but hemimorphic in form. It is honey-, citron-, or orange-yellow with an orange-yellow streak. It occurs in trap rock cavities and ore veins. It is sometime associated with smithsonite.
Hardness - 3.5 to 4, density - 3.8 to 5 avg. 4.5, Cleavage - 3 distinct at 120 (hex. Prism) and one imperfect perpendicular to the others, Fracture - uneven, Diaphanity Ð opaque to translucent, Luster Ð adamantine to resinous, Habits Ð colloform, encrustations, and radial.
Questions
What is the name of the mineral?
What was the mineral named for?
What is this mineral mined for?
What is the metal used for?
What minerals might associate with this mineral?
What is the name of its polymorph?

Answers for last month's mineral
What is the name of the mineral? Argentite
What was the mineral named for? Its silver content, argentum is the Latin name for silver thatÕs why its chemical symbol is Ag.
What is this mineral mined for? OK. A toughie hereÉhow about silver!
What is the metal used for? Silver and gold alloys for jewelry, photographic film (yes, they still make that stuff), electrical conductors.
What minerals might associate with this mineral? Lots of Ag minerals, like the Ag sulfosalts, native silver, pyrite, other sulfide minerals
Why is this mineral not REALLY present in anybody's mineral collection? It is only stable above 179¡ C (354¡ F). Acanthite is the name of the silver sulfide below that temperature. Cubic crystals of silver sulfide in collections are acanthite pseudomorphs after argentite. (OK, if you MUST have argentite in your collection, get one of the pseudomorphs, put in your oven at 375¡ F ,to be careful, and voila!)
Localities Ð (Just list the famous/important ones)
--NM Ð Alhambra mine, Grant Co., New Mexico.
--USA Ð Comstock Lode, Virginia City, Nevada; Butte, Silver Bow Co., Montana; White Pine mine, Ontonagan Co., Michigan; Defiance mine, Inyo Co., California
--World Ð Kongsberg, Norway, where it occurs with
Silver; numerous places in Germany, notably the Clara and Wenzel mines in the Black Forest, and in Freiberg and Scheenberg, in Saxony, Germany; numerous localities in Mexico, most significant are Batopilas, in Chihuahua , where it occurs with Silver, and the Reyes Mine in GuanajuatoPaul Hlava 060312

MapMuse
Hi,
I am writing to let rock enthusiasts know that MapMuse.com has added nationwide maps of Rock Shops and Rock Clubs and Societies to its services. Following is the link to the Rocks and Minerals Directory, which has the links to the these two maps:
http://find.mapmuse.com/re1/mmHomeInterestsList.php?cat=Rocks%20and%20Minerals
The idea is for rock enthusiasts to build upon what we have started by enhancing the information we already have, and adding clubs and shops that we have missed. Please note that descriptive information, as well as photos can be added directly to the profiles by our visitors. There is an ADD and EDIT feature on the site (you can refer to http://find.mapmuse.com/re1/mmFAQ.htm#A4 if you have any questions about making changes). Through this kind of community effort, we hope to have the most comprehensive, and descriptive maps for rock enthusiasts to use at home, and on their travels. We would appreciate if you would participate in the process, by checking if your local rock shops and clubs are mapped, enhancing information as you see fit, and adding shops and clubs that we missed. Also, if you find these maps useful, please pass the word on to like-minded friends.
Lastly, if you have a rock related website, or a rock related blog or newsletter, we would appreciated a link.
Thanks,

Museum of Natural History Events
As a member of the Museum of Natural History, I get various Museum publications. My most recent is the Calendar of Events for March and April. Following are those events in which I have an interest, and thought other members might as well. All talks begin at 2 PM.
For a full list, with additional information, log on to www.NMnaturalhistory.org
March 21 - "Have Fossils, Will TravelÓ.
March 28 - "Unique New Mexico Rock: The Museum Travertine FloorÓ.
March 30 - "Triassic Tree Climbers"
April 13 - "Diplocaulus".
April 18 - Fossil Identification April 20 - "Walking on GarnetsÓ.
April 27 - "All About dirt".
Museum volunteers will direct you to the location of the events.
These are advertised as "15 minute talks" but one or more of the speakers may get carried away. I have attended a couple of those lectures but did not stay long enough to make a comment on them as they were not in my field of interest. The time may also be extended depending up the number and variety of questions on the part of the attendees. Being a Member of the Museum is a stated requirement. I don't know if they take roll or not. Depending upon your interests, it maybe cheaper to be a member rather than just paying periodic entry fees to the Museum.
Oh, I must include one event that all you will need is your TV: "Volcanoes in New Mexico" will be available May 1 on KNME-TV at 9 PM. In the mean time, you may want to get a copy of the recent issue of "Earth Matters", published by the Bureau (free to us), which includes the non-technical article "Volcanoes of New Mexico".
