From the President

You may not know this, but a whole lot of things are going on behind the scenes. Though the Board hasn’t met officially this month every board member is up to something or another.

Some of this flurrying is happening around our upcoming show. Paul Hlava’s Show Committee is implementing the Plan…we have a full slate of dealers, staffing positions are filled and flyers are available, so be sure to pick some up for dissemination at the next meeting.

Rex and Grant our Co-VP’s of Field Trips have already outlined a whole year of collecting adventures for your enjoyment, and Anita and Marcus have booked a number of exciting speakers for our monthly club meetings. Our editor, Jay Penn [and wife Amy], trekked to Tucson for the HUGE annual show there to shop for the door prizes that are given away each month at the meeting. They were guided in this by veteran and Club Historian, Dave Moats who has passed on the job to Jay. Jay has also been working since last years’ show to assemble, sort, clean, and label the inventory for the Junior Table. He has also given buckets of tumbling rough to Walter Morris who has processed the material that becomes the always popular smooth rounded stones that everyone likes to paw through and kids just love to possess.

Speaking of kids, our Co-Chairs for the Junior Club are implementing the Future Rockhounds of America program with our younger members. This nationally designed and sponsored program rewards learning and achievement in a variety of subject areas related to the hobby. Well, that’s just a sampling of what’s going on… you may rest assured that the Board of Directors is working all the time to make this club a dynamic organization that delights our members of all ages and interests.

And we’re having fun, so join in as much as you can!

Minutes and Meeting Reports

General Meeting Minutes

January 28, 2008

The meeting was called to order by President Suzanne Seymour at 7:36 p.m. She welcomed guests and new members.

Amy Penn was at the back of the room accepting membership applications and renewals.

Grant Kuck talked about the field trips this past weekend to Kilbourne Hole and to Bishop’s Cap. There were 30 people on Saturday and 12 on Sunday. Everyone had a really good time and the weather was great! The next trip is to Hatchita on February 23rd, where people will look for turquoise and several other minerals. On February 24th members can meet at the McDonald’s in Deming and proceed to Cook’s Peak for fluorite and other minerals. The next field trip after that is to the Nakaye Mines for barite, fluorite and calcite. In May, the club may go to the Mayflower Mine near Socorro. Advanced signups will be required for that trip.

Kathy Lawicki needs people to sign up to bring snacks for the meetings in April and later.

Hank Miller circulated a signup sheet for volunteers for the Treasures of the Earth (TOTE) show raffle sheets. Gwen Poe is coordinating the dinner party for the TOTE show vendors and members on March 13th and said that there will be approximately 100 people, including about 30 vendors. The club will provide Rudy’s brisket and ribs, and members are to bring a potluck side dish. Jay Penn talked about the junior table, where kids can shop, and needs people to man that table. Paul Hlava advised that proceeds from the show help to support the scholarships, picnic, holiday party, science fair prizes, etc. Signup sheets were circulated for volunteers to set up, attend to the admissions table, spend the night as security guards, and tear down the show.

Parking passes and free admission to the show will be provided to all volunteers. Small groups such as scouts, students and their leaders and teachers are subject to free admission. They need only to coordinate with Mike Sanders to gain admission. Mike Sanders also reminded everyone that the theme for the show is quartz, and people wishing to display should contact him.

Anita Willard introduced club member Todd Brown, who gave an entertaining presentation about his and his wife Pat’s turquoise mine, museum, and home near Cerrillos.

The meeting was adjourned at 8:50 p.m. for refreshments and door prizes.

Jr. Club Meeting Report

January 28, 2008

The topic for the January Jr. Club meeting was Collecting, and attended by 13 junior club members. This was our first meeting since joining the AFMS Future Rockhounds of America club, and the junior members each received the FRA membership badge. Several of the junior members brought in their own rock collections, and Jim and Earlene brought in several of their own collections.

We discussed building a collection, cataloging and labeling, storing and displaying a collection, and reporting about a collection. After the discussion, all were invited to show and talk about their collections. The junior members completed all of the requirements for the Collecting merit badge, and will receive them at the February Jr. Club meeting.

Treasures of the Earth - 2008

Howdy Folks. The show is coming up fast! As I write this it is just about 5 weeks to our show (YIKES!). I was really gratified by the wonderful response I got for set-up and tear down volunteers at January’s meeting. I expect that we’ll be able to set the show up in good time. And the tear down should be a breeze. Of course, if you didn’t sign up and feel like rolling up your sleeves, you can just show up and pitch in. That means everyone will get finished quicker and so you all (I suppose that should read "all y’alls") can relax with coffee/tea and some nice, healthy, dietetic donuts! I do still need some folks to help with overnight security on Thursday. If you are interested, call me at 255-5478 or email hpf5@qwest.net

Dealers. We have no booths left at the show. Nada, zip, zero. They are all gone! They are all paid for except those few that just got the paperwork and the contracts and money are coming by the notoriously speedy(?) NM mail, but they have been promised

Publicity for the show is underway. My supply of garish flyers is getting quite depleted but you are all welcome to the rest! We will soon send a stack of these flyers out to each of our out-of-town dealers. We have 6000 postcards to mail out to our lists of past attendees and to pass on to treasured friends and another 1,000 with blank backs for us to sell as regular post cards. This was Gwen Poe’s suggestion. If you want some, they are $0.30 each or 4 for a dollar.

The various rock and mineral magazines have been contacted and we are preparing public service announcements for radio and TV spots. Newspaper ads will be sent in at the proper time. Of course, one of the best advertising media is you. Word of mouth invitations are one of our most popular and effective ways of getting new folks (and returnees) to come to the show.

Once again I will plead for more people to get involved with the show committee. Don’t forget that show workers get free admission to the show and free parking passes. If you are a club member but not working at the show you have to pay to park and to get in. And you don’t have to work ALL the time. Work a stretch then browse the exhibits and dealers, buy some stuff, and then repeat. And please remember – make sure you have fun at OUR show!

Gwen Poe will be coordinating the World Famous Albuquerque Gem and Mineral Club’s annual pre-show Pot Luck supper! I’m sure she would also appreciate a number of angels to help her with that FUN job. I want you to think about what generous dish you can bring to share with the rest of the club and our guests, the dealers. If’n I remember correctly, the club supplies the main dish. Club members supply casseroles and hearty salads and such like. Hmm. I may bring tamales again. Oh, Gwen is handling hospitality for Thursday and the team of Amy Penn and Carolyn Wood will do Friday thru Sunday. They might be able to use another person or two to help take care of coffee, "power pills" (donuts), et cetera, on Friday, Saturday, and Sunday.

Others interested in volunteer help include Kimberly Richie (admissions) and Hank Miller (door prizes & raffle),

And lastly - The club has been having new display cases made the last few years. As these new ones arrive we are trying to dispose of the old cases. They are free to any club member who asks for one. Eventually we will dump the last of them.

I will be out of town from Feb. 8 thru March 3. If you need help or info try Suzanne or Amy, or some of the other board members.

Paul Hlava, Chairman - Treasures of the Earth Show

TOTE Silent Auction

Our Treasures of the Earth show is quickly approaching and it’s time to make your plans for the silent auction – whether you are donating, selling or buying.

Donating: We need donations to sell at the club tables. You can take them to the silent auction area beginning Thursday night at the pot luck dinner. Most of the tables get sold in advance to dealers and club members so your donations of a few better pieces rather than large numbers of the same thing are much better for the club. While your donations are greatly appreciated, we don’t need flats of scrap material.

Selling: Selling at the silent auction is a great way to offload some of your excess material - it also makes money for the club which is a good thing. You can expand your collection by purchasing flats of material for a good price, keeping the best for yourself and selling off the remainder for enough to pay your table cost and recover your cost of the whole flat. Minerals for free!

You can buy a six foot section of lighted table for $20 per auction. There are three auctions per day of the show and you or a representative needs to be at the table during the auction (limit of two adults per table, please). You can sign up for table space on a first-come basis beginning Thursday night at the pot luck dinner.  You will need to pay for the table in advance in order to reserve it. See Rex Nelson or Jim Van Loan to sign up.

Buying: Because of the way we now do the silent auction, there is often some really nice material available at great prices. You should try to attend as many of the auctions as possible to see what is offered. Whether you are working at the show at auction time or not, it’s worth the trip to attend every auction if you love a bargain!

Thanks for your support. The Silent Auction Staff: Jim Van Loan, Grant Kuck, Jim Hill and myself, Rex Nelson

 

AGMC This Month

Saturday, Feb 23rd

Sunday, Feb 24th

AGMC Field Trips

Hachita, NM

Deming, NM

9:00 a.m.

Saturday, Feb 23rd Hachita area: The meeting or congregation place will be at the Baptist Church in Hachita at 9 AM. After a short briefing and coffee we will begin our collecting trips at 9:30. Please note that it is not absolutely positive that the church will be open for our use so we may just be using it as a meeting place. Collecting will include turquoise and misc. other minerals.

Directions: Take I-10 west approximately 30 miles from Deming. Go south at Exit 49 and travel 19 miles on NM146. Hachita will be here at the intersection of NM146 and NM9. The church will be visible by locating the small bell tower and cross approximately one block from this intersection. Hachita’s most visible land-mark is a large black water tower.

Note: Hachita is about 50 miles from the nearest services. Occasionally some services are available but do not count on it. Gas up and bring food and water. Restrooms are not anywhere around except at the church if it’s even open. Most of the roads are primitive but fair when dry. Carry a small shovel for deep ruts if you like to wander about in remote areas. Homeland Security and the Border Patrol rule in this area due to its remoteness and border proximity. If you are stopped, have ID available and be courteous. If you find a drop such as a bundle of goods or whatever, do not touch it. Leave it alone and report it at the first opportunity. It is likely under observation by some undesirables (bad guys) or agents. Helicopters and aircraft frequently patrol the area, especially if you set off one of the sensors. If you get buzzed, just wave.

Most of our collecting will be by digging in dumps or surface collecting. Carry something to wrap specimens in and possibly a small collecting bag for your treasures. Shade is best to hunt for turquoise. If it has been raining or snowing every piece of turquoise will stand out and look great. You can always sort the pieces out later after drying. Possible digging tools for the dumps would be larger picks and rock hound picks. Garden tools sometimes work.

Turquoise: The turquoise in general is blue to green and anywhere in-between. Green is frequently prettier than blue when polished, making green very collectable. The hardness may very from very hard to chalky. Chalky material can be treated to increase the density thereby becoming somewhat polishable. Turquoise is generally considered pure or matrix turquoise. Matrix turquoise means that it has some of the rock mixed in with the turquoise. These pieces are sometimes prettier than the pure stuff. The best places to collect are in the turquoise mine dumps or waste piles. Especially in places that you find small fragments on the surface. You may also find old sorting or cobbing piles where the miners sorted and separated the rock and turquoise. Look for nuggets, thin plates or seams, disseminated grains or just ordinary fragments. Small veins in rocks can be hard to see so check them carefully.

Checkout will be at the church NLT 5:00 PM. This is necessary due to the vastness of the area. We would like to know if anyone is stranded or lost. Traveling in groups is best and safest.

Sunday, Feb 24th Deming area: The meeting place will be at McDonalds near Deming’s I-10 Exit 81. Departure to Fluorite Ridge at the south end of the Cooks Range will be at 9:00 AM sharp. Collecting will include fluorite with barite, manganese minerals, and various agates including carnelian.

PLEASE NOTE: Both of these areas have dangerous mine workings including open shafts. Rattlesnakes and scorpions persist in this area even during the winter. Please use caution at all times. Dress properly with long sleeves and full length pants. Gloves protect hands, especially if you fall down. Every care must be used with underage members to keep them safe. Do not let them wander or be alone for any time whatsoever. The same goes for pets. Dress warm with removables.

See you there, Rex & Grant

"Our ongoing geological investigations of the northern Tularosa Basin"

by Dave Love

Dave obtained a PhD in Geology from UNM and was a member of AGMC many years ago. He currently works for the New Mexico Bureau of Mines & Mineral Resources studying the landforms and sediments preserved in the northern Tularosa Basin.

He will discuss the role of springs, wetland habitats, rivers, and lakes in forming the floor of the basin over the past 50,000 (or more) years, including the history of the White Sands gypsum deposits.

 

Miscellaneous

Editor's Opinion

The following is solely the opinion of the editor------------today.

I might change my mind tomorrow.

I heard this from Todd Brown at the Christmas Potluck.

How do you confuse a miner?

Give him two shovels, one for each hand.

Then tell him to go into the mine, and take his pick.

Field Trips

January Field Trip Report

Saturday morning, January 26th, 30 members of the Albuquerque Gem and Mineral Club gathered at McDonald's just off University Boulevard in Las Cruces. In between bites of Mcmuffins, Mcburritos, and Mcdrinks we talked about Kilbourne Hole and passed around a sample piece of peridot that had been found there. Life time club member Ray Demark put in an appearance but did not go on the trip as he had a previous engagement. At the appointed time we all took off from McDonalds and headed south into Texas. From there we drove west back into New Mexico where we drove to the south end of the Kilbourne Hole (which is located about 30 miles of driving WNW of El Paso.)

There we were met by University of Texas El Paso grad student Keith Cardon and UTEP doctoral student Michael Feinstein, thanks to UTEP grad student Joe Lori who helped set the whole thing up. Anyway Keith and Michael lectured us on the geology of Marr Volcanoes in general and the Kilbourne Hole specifically. I learned that the Olivine group includes magnesium rich Forsterite and iron rich Fayalite. And when these two minerals are chemically combined we have Olivine. Following their talk the two UTEP students took us to the north side of the Kilbourne Hole where collecting is supposedly the best. A thanks and tip of the hat to Keith and Michael for spending a major portion of their day meeting us at Kilbourne, giving us a lecture, answering our questions and then taking us right to the collecting spot. You couldn't have asked for a better set up.

Weatherwise the day was overcast with the sun coming out later in the afternoon making it just perfect for collecting. I thought the club would have to desend into "the Hole" quite a ways before we started finding any olivine, but almost from the moment we parked the cars and started our descent we began to find rocks or bomb blasts just filled with the mineral. By the way, the yellowish green variety of olivine is known as peridot. Olivine can also be yellowish brown or reddish. Ray Demark also reports that Diopside has also been found at this site and I did find a small piece of obsidian.

A special thanks goes out to Bill Curtis for bringing his 4 wheeled all terrain vehicle along just in case we needed it. Also another thanks to Bill for putting up a number of AGMC members for the night so that we could go to Bishop's Cap the next day.

I also want to thank Bill and Kay Walker and Rex Nelson for all their time in preparing everything for this outing. Bill and Kay helped Rex locate and check out Kilbourne Hole in advance. Believe me it made the field trip that much easier. This was one of those trips where you could not help but find olivine . . . well I suppose you could if you shut your eyes. Anyway we had great weather, great collecting, and great fellowship. Upon our return to Las Cruces about 20 of us went out to "Dicks" for dinner. And as my report began in a restaurant I'll end it there in another. Good food to wrap up a good day!

Sunday morning, January 27th, 12 members of the AGMC once again gathered at McDonalds in Las Cruces. Having survived the Kilbourne Hole Field Trip the twelve were anxious to test their skills on Bishop's Cap. So after finishing our Mcbreakfast we all piled into our vehicles for a game of follow the leader. Once again we headed south of Las Cruces toward El Paso but this time we headed east from the interstate and in due time arrived at the Bishop's Cap Prospects. We learned from Rex Nelson, who has collected here in the past, that there was very little mining going on. The minerals of note for this locale were barite and fluorite. Nice pieces of barite could be found on the dumps or removed from the inside and the outside wall of a mine.

I believe it was Dan and Denise Williams who hiked up the mountain and came back with reports of some good pieces of fluorite. That was all it took for Jim Hill, his faithful doggy companion Howdy, Cathy Stringfellow, and myself to follow in their footsteps. Sure enough there were a number of rocks with rich blue and dark green pieces of fluorite in them. Jim even discovered a seam of fluorite that disappeared into mountain. This is definitely an area that encourages some exploration. Once again thanks goes out to Bill Curtis for bringing his ATV along just in case we needed it. The way he went up and down the mountain I'm going to have to think about renting one some time, especially if it has a place to carry rocks and minerals.

Eventually everyone had their fill of collecting and it was time to leave the Bishop's Cap Prospects and head back to Las Cruces. From there it was back to Albuquerque and the regular work a day world. However before we left Las Cruces we had to make one more stop where Bill Curtis, Rex Nelson, Jim Hill, and I stuffed ourselves with warm, freshly made pizza at Ci Ci's - a good place to end another good day of collecting in the field.

Grant & Rex

March and April Field Trips

The tentative field trip for March (Copper Flat) is possibly going to be changed to the Nakaye Mine. As it turns out, much of Copper Flat Mine is under claim and would require a considerable effort to obtain permission to access. The Mayflower Mine on Socorro Peak would replace Nakaye for April. This change is pending approval from the club officers at the next board meeting. Approval for this trip by the Energetic Material Research and Testing Center (EMRTC) has been verbally OK’d by Alan Perryman who will also act as our guide.

For those members who are relatively new, this site is on the peak behind NM Tech at Socorro. This location was last accessed by the club through arrangements by Ray DeMark and Kimberly Richie during the March 2002 field trip. The Home Page for our website at agmc.info has an excellent picture showing the view from the Mayflower Mine. Information about that trip is also available on this website in the archived March and April 2002 News Nuggets.

Please note that members wanting to go on this trip will need to submit their name in advance for submission to EMRTC. Street vehicles are ok for this trip as EMRTC personnel will provide transportation the last ½ mile or so. However, hiking up the mountain will be a vigorous 1000 feet climb requiring good health and stamina. We will address this change again in the March Nuggets.

See you there. Grant and Rex

 

Mystery Mineral

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 hpf5@qwest.net 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! 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 published in the News Nuggets. Good luck and have fun.

Last year I discussed minerals that are named for some physical property that they possess. This year I thought I’d concentrate on minerals that are used as gemstones. Hmm, I might even include a rock or two used as gems.

This month’s MM is an oxide gem mostly found in marbles (both calcitic and dolomitic), low silica igneous rocks like peridotites, kimberlites, basalts, and alkali igneous rocks, also pegmatites, and alluvial rocks derived from all of them. It is cubic and often forms crystals; these are dominated by octahedral faces. It has no cleavage and the fracture is uneven. It can be colorless, red, blue, green, and brown, Sp. Gr. = 3.57 - 3.72, H = 8, transparent (gemmy) to translucent to opaque, luster -vitreous.

"Our ongoing geological investigations of the northern Tularosa Basin"

by Dave Love

Dave obtained a PhD in Geology from UNM and was a member of AGMC many years ago. He currently works for the New Mexico Bureau of Mines & Mineral Resources studying the landforms and sediments preserved in the northern Tularosa Basin.
