AGMC Field Trip
MolyCorp Mine
9:00 am - ?? pm
Bruce Walker, the mine geologist for this mine has kindly agreed to provide us with a tour of the Questa Moly Mine. We will assemble at the parking lot near the Administration Building from 8:30 through 9:00 AM. The tour will begin with a briefing at the Administration Building at 9:00 AM sharp. While touring the mine we will observe such features as alteration scars, an open pit, an ore body subsidence area, and some major rock piles.
The elevation of the tour will range from 7875’ at the Administration Building to as high as 9800’, so dress accordingly. Dressing in layers is a good idea. We will be required to wear long pants and boots. Safety glasses and hard hats are also required so bring them if you have them. The mine will provide these for those who don‘t bring their own. We will not go underground on this tour. Gloves are desirable also as rocks can easily fall down on your hands while collecting at the ore pile.
The minimum age in the past has been (9) nine years old and I will continue trying to verify this with Bruce Walker prior to the next club meeting.
The mineral collecting portion of the trip is usually surface collecting at the main ore pile. Suggested tools are a geology pick, chisel, and a 3 or 4 pound hammer for breaking into larger rocks. Additionally, bring something to wrap and carry your treasures. Some will be very delicate. Bruce has indicated that we could find some beryl if we are fortunate. The most common minerals that can be collected include molybdenite, pyrite, quartz, muscovite, biotite, fluorite, calcite, and feldspar.
Due to the remoteness of the mine and the length of the tour, please bring your own food for the lunch break.
This mine is about 3-31/2 hours drive from Albuquerque. Drive north of Espanola on NM68 to Taos. Continue north from Taos on NM 522 to Questa. Travel east from Questa on NM 38 towards Red River. The cutoff to the left is about 3 1/2 miles east of Questa and across from the Goat Hill Campground. Follow the road uphill to the Admin Bldg. Allow yourself plenty of time for a safe and successful trip.
Bruce walker is a very knowledgeable geologist and is the "expert" on this mine, so please feel free to ask questions at the briefing.
The features we will observe and the scenery are worth the trip so make every effort to go on this tour and please give Bruce Walker a big thanks at the end of the day.
DRIVE TIME: 3 to 3 ½ hours
MEET: At the Admin Bldg. NLT 9:00 AM. Leave early or leave the day before and campout.
TOOLS: Geology pick, chisel, 3# or 4# sledge hammer, wrapping material and container. A hand lens is also nice to have.
VEHICLE: 4-wheel/high clearance vehicle. We will caravan as much as possible while on the tour so a street vehicle will suffice if that’s what you have.
SPECIAL INSTRUCTIONS; Bring hard hat, safety glasses, gloves, and wear LONG PANTS AND BOOTS. The mine has safety glasses and hard hats but if you have your own, bring them.
See you there,
Grant and Rex

________________________________
Editor's Opinion
The following is solely the opinion of the editor------------today.
I might change my mind tomorrow.
Boy was it HOT at the last club meeting or what? And the microphone wasn't working either!! BUT, that isn't any reason for a portion of the audience to get up and start talking before the speaker was done.
I'm sure all of us have endured harsher conditions with more grace. I hope we can do so in the future.
Also, please teach our young people that the refreshments are for after the speaker is finished and the chairperson has announced that it is time for refreshments.
________________________________
Discourtesy
I was appalled at the complete lack of courtesy shown by some AGMC members to our speaker at the August meeting. Even as it is inappropriate for members of an audience to disturb a speaker with side conversations while he/she is giving the main body of a presentation, it is just as inappropriate to do so while the speaker is answering questions from the audience after the main part of the talk. The question/answer period IS part of the presentation.
Dr. Boslough is an internationally recognized expert in his field and he gave a talk that most of us found fascinating. In addition, his visuals were wonderful and he is a better speaker than most. Even if the speaker were some lesser star, it would still be rude of a few folks to disrupt the Q/A part of the talk. I expect better from the members of my club.
I ascribe the prevailing lack of courtesy by Americans, in general, to be due to television. It is quite common for folks to talk while a TV program is in progress. That’s OK; it is your home. But this practice is not appropriate for many PUBLIC venues such as concerts, plays, recitals, motion picture theaters, and seminars/talks. Please remember that our meetings are public venues and act accordingly. Once the speaker has finished for good and the president, program VP, or other officer has declared it time for refreshments, you may have/are encouraged to have those side conversations.
I hope that the members of AGMC will never embarrass me like this again. (And it takes a lot to embarrass me.)

Field Trips
August Field Trip Report
The field trip to the Globe and Coats mines was successful in every way. Seventeen members met at La Madera's only intersection and proceeded to the Globe Mine. Shortly thereafter three more members drove up thanks to directions by some La Madera residents. Small town with very nice people.
In general the collecting at the Globe was good for muscovite and ferrocolumbite. I noticed that several members found manganocolumbite in the form of free crystals but I didn't see any in matrix. A little bit of fluorite was found but nothing particularly noteworthy. Some very nice ferrocolumbite specimens were found.
Towards lunch the members proceeded to the small village of Petaca and then up to the Coats Mine. Seeing this village was worth the whole trip. The highlight of this location was to see where Jim Van Loan found his world class, museum quality, manganocolumbite that he exhibited at the club meeting. Thanks Jim. Who would have guessed that such a specimen could come from that spot.
I believe most of us were worn out by this time and the waste piles were very steep and hard to work on. Jim found some nice spessartine garnet in waste or float. The source was never found. About 3:30 or so we loaded up to head home.
Several of us stopped by the La Madera fluorite prospect on the way back and tried very hard to come up with something collectable. In the end, it turned out that the nicest material here was some micro fluorites found by Craig Pearson. This was only right since micros are Craig’s specialty.
Thanks to Craig and Jay for the help in locating the Globe mine on Friday to insure that we could lead the participants to this remote site on Saturday.
Sorry that Grant didn't make it but he is well again and will be on the Moly Mine trip.

October Field Trip
Rocks and Stuff along the Turquoise Trail, a General Geology Field Trip Led by Paul Hlava
October 20th
This is a road trip with a lot of arm waving that will take us past a number of different kinds of rocks and mines. We’ll start with stops in Tijeras Canyon to look at Precambrian gneisses and granites, Permian redbeds, and younger lamprophyre dikes. Then up highway 14 past various sedimentary rock exposures and a stop at the old gypsum (alabaster) quarry. On past more sedimentary rocks and a number of igneous rock intrusive complexes, with stops here and there to look at and/or collect some rocks and more arm waving. One of my favorite stops is a few miles south of Madrid where we might see/collect some fossils (Inoceramus clams) in metamorphic rock!
We will pass through Madrid and Cerrillos, doing some arm waving at various features (gold mines, angular unconformity, overturned bedding, etc). I plan a stop in Cerrillos at (club members) Todd & Pat Brown’s "Casa Grande Trading Post" where we can restock provisions, get a cabbing demo from Todd, use the out house, and purchase a few curiosities of natural or cultural interest.
Going further north, we will turn off 14 onto 586 and take that short cut over to the La Cienega entrance to I-25. On 586 we will stop to look at a volcanic neck (dacite), a famous turquoise mine (the Tiffany Mine – but we can’t go in - SORRY), goggle at the movie ranch in the distance, and collect cobbles of limburgite from a lava flow.
The trip officially ends at the limburgite but I will lead you to the Cienega intersection. From here you can go south and back home or north and tour a bit of Santa Fe and maybe have dinner there before returning.
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.
Questions? hpf5@qwest.net or 255-5478
Paul Hlava
Note: some suggested items to bring along include geology pick or a reasonable substitute, small collecting bag, and a pencil and paper for those who desire to take notes.

Mystery Mineral
From the devious mind of Paul Hlava
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. I expect the Top Guns in the club to be able to guess the name off the top of their heads, or not. 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. 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 some physical property that they possess.
This month’s MM is a rare, chemically complicated, sulfosalt with unique morphology found in hydrothermal tin veins. It is triclinic but It has no cleavage, usually lead gray to grayish black with a black streak, metallic, Sp. Gr = 5.41, H = 2.5, malleable.
Questions
What is the name of the mineral?
What is the origin of the name?
What is it mined/used for?
What metallic element(s) is(are) present?
Which metal is most important and what is it used for?
Besides sulfur what other non-metallic or semimetallic elements are present?
What is this element 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? Albite
