Lake Jaco, Chihuahua never was the source of garnets. It was a way to throw off competitors. Some people labeled specimens in confusion with the Xolostoc, Morelos, Mexico, pink garnet location which makes for some very messed up labels. Other labeling errors are Sierra de las Cruces or Sierra de Cruz.

The closest town is Hercules, Coahuila and the area is part of the Municipio de Sierra Mojada, this could be added to the labeling. The article in the Mineralogical Record issue from November -December 2003, volume 34, Number 6 contains great info on the locality.

The proper locality for the raspberry garnets is
Santo Domingo claim
Sierra de Cruces
Coahuila, Mexico

The deep red garnets in wollastonite were mined by Sutton and Griffis in 1994. This hill (cerro) is a few kilometers to the SW of the raspberry location. Two specimens are on the right side of page 77 in the Mineralogical Rec article. This area was mined out and are from the
Cerro de Moka
Sierra de Cruces
Coahuila, Mexico

The pink and green grossular are from locations to the NE of the raspberry location.
Sierra de Cruces

Having done this, have to say I was 100% right to do it!

Don't forget, the clay that you clean off your minerals when you bring them home is a mineral too - removing calcite is no worse than removing clays or iron staining, from quartz.

Always record in your catalogue how the specimens were cleaned though.

As John says, probably Tennantite from this location. Since a true end member is seldom seen, perfectly correct to call this Tennantite-Tetrahedrite Series and closest to the arsenide end. So Tennantite is correct in my opinion as well. All the best.

I could think that this comes down to your own preference, and what you would like to see.

For example, if you had an interesting specimen of ____ covered by lovely crystals of ____ , would this be a big issue between mineral collectors?

For example, if I had a lovely specimen of fluorite, covered by beautiful crystals of calcite and you dissolved the calcite, does this become some kind of moral issue between collectors?

As in 'How could you destroy those beautiful ____ crystals just so that you can see ____ ?!?!'

Have you ever had a disagreement in this regard?

I wonder if this is akin to when people remove the wild flower 'weeds' that are native to the area, that are invading their lovely and well cared for flower garden...

Greetings.

I am wondering if the bottom mineral could be tetrahedrite.

It's for sure not galena, as it has a very rough cleavage.

The specimen label says 'Tsumeb Mine' but maybe it could be Berg Aukus?

Any help would be very appreciated.

And claim owners: the greatest threat we face is not from someone who collects a few rocks from our properties. Our real enemy is the increasingly powerful (given the political situation in the U.S.) environmental lobby who wants mining claims severely restricted or eliminated and mining and even collecting, outlawed. In the big picture, those collectors, while irritating because of what they remove from our claims, are likely political allies.

POST YOUR CLAIMS! If someone removes the sign, post it again. It really is a courtesy to others and preserves your property and prevents trouble for them. A win/win, don't you think?

I'd like to hear the opinions of other claim owners.

Chris is correct in saying that this paper was published on the GeoScienceWorld service for the October issue (it went live on Friday of last week; it was accepted at the end of August). The Society has invested in a 'publish ahead of print' service in the hope that it will serve to get material online as quickly as possible. At present we don't have a 'publish ahead of print' service on the Ingenta platform (referred to by others in this thread as the "MinMag" page), hence the difference in what is presented. As soon as all of the papers for October are complete, they will be posted on the Ingenta service.

One point to note: all individual members of the Society subscribing to the journal are entitled to access MinMag on both the Ingenta and the GSW services. To access MinMag content on GSW go to www.minersoc.org (the Society website homepage) and click on "login" on the left-hand side. You'll need to register the first time you use the service. Please contact me - Kevin Murphy (kevin@minersoc.org) if you need any assistance.

Regular readers will be aware that MinMag has been running behind schedule for some time. We're working hard at completing the catch-up; hence the closeness of the August and October issues. Membership for 2010 costs £33 and for e-access to the journal a further £20 - so excellent value. (For non-members, you can also join up online!)

That it more than likely some kind of byproduct of industry.

The main reason I am thinking this is that it's entirely Melilite, as opposed to having any kind of other mineral at all or any matrix.

Every single spot on the specimen is Melilite.

Do you have a photo of your specimen?

It would be interesting to compare.

Cheers,
