Identity HelpNeed More Specific Nevada Locality for This Rock

20th Feb 2013 01:04 UTCSteve Stuart Expert

Hello, all!

Just got back from Tucson where I purchased this specimen of "filiform" mimetite on vanadinite, with only the locality attribution as Nevada. I would think that the habit and association may be distinct enough to allow for a more specific locality than just the state of Nevada. Any ideas? The last image is of the old label, from the collection of T. M. Phetteplace, and apparently acquired from Susie Davis at the Phoenix Show in March 1962 for $1.50!

Any opinions as to where in Nevada this unusual association of mimetite and vanadinite comes from?

Thanks!

You might try contacting Scott Kleine of Great Basin Minerals as he specializes in Nevada minerals. I'm not sure what his current contact information is as his website is very out of date. I did talk to him in his dealer room at the last Denver show though. There is also apparently a very detailed "Minerals of Nevada" book that one could use to narrow down the possible locations.

Hope this helps!

I have the Minerals of Nevada book and did not find anything to help pin this down. I also searched for the mimetite/vanadinite association in Mindat, and looked specifically at the localities in Nevada that share these two species. No images as distinctive as these are.

Vanadinite with fibrous Mimetite, Elko County, Nevada. Translucent red-brown hexagonal vanadinite crystals to 1.5 mm with golden needle-like fibrous mimetite crystals to 3 mm long.

Hal, that sure looks like my specimen. Any mine associated with it?

4th Mar 2013 15:18 UTCHarold (Hal) Prior Expert

No Mine information available - believed to be collected in 1950's. One of my 50 year interests has been locality research, as a result I've accumulated 100's of books, documents, pictures, etc. that I use for my personal study. I will dig a little deeper and see if I can find a mine association. I was surprised how closely the material resembles yours.

This image showed up in a 2007 Mindat thread by Rich Dale as being from Elko County with a request for locality info. No additional info was provided as to mine, and several suggested it was not Nevada. I have no doubt your specimen is from Elko County, however, would not venture a guess as to Mine at this time.

5th Mar 2013 01:42 UTCSteve Stuart Expert

Tried to e-mail Scott Kleine at Great Basin Minerals and it came back as undeliverable. There appears to be three specimens of similar association: mine, Hal's and Rich Dale's. Anyone have Scott Kleine's contact information?

Maybe I'll just post my photos to Elko County, Nevada in Mindat.

Thanks for the input!

Nowadays it seems amazing to us that back in the 1950s and '60s it was quite common for collectors to attach little importance to detailed locality information. Even in Federation competitive displays the name of the state was enough!

I just want to point this out so that Steve won't think there was anything particularly unusual about his 1962 label with only the state recorded. It makes one wonder whether future collectors, 50 years from now, will look back at our current labels and shake their heads at how much "essential" data we primitive early 21st century types weren't accustomed to put on our labels!

Not a large amount of Vanadinite was mined in Elko County. Very similar color vanadinite was found in late 1800's from an unnamed mine at the old ghost town of Crescent (Not Crescent Valley) in Elko Co.,

All you need on a label is the latitude/longitude of where it was collected (to a good accuracy) and date of collection. Anything else* is pretty much redundant :)

Jolyon

* I'd add to this a record of cleaning, treatments, repairs, etc. And if you want to add what mineral you think it is, that's fine, but hardly critical. Future generations can always reanalyse it.

I have bought some stuff from him so I assume his contact info must be on the labels. I'll see if I can find them. I'll give you his address and phone number via private message as I found one of his cards. The website is the same though.

Called him today and left a message. We'll see what happens!

I disagree with Jolyon. Portable GPS units are a new thing, and most localities did not refer to lat/long, at least until the last very few years. Township, range, section still works. I am a geologist and active field collector, but I do not have or use GPS. It is a pain to have to refer to the latitude and longitude. One must have the proper maps, scales, etc. Hopefully, mine names and geographic locations will not go out of style. And the lack of a GPS has not prevented me from figuring out where I was (except briefly underground). Nor have solar flares, a glich in a satellite, lack of satellite coverage, bad/dead batteries, etc.

Note that Mindat's own locality database refers to locality names- not latitude and longitude.

6th Mar 2013 19:42 UTCJolyon Ralph Founder

All I mean is that for accurate recording of data on a specimen, the latitude/longitude is all you need (and I disagree that it's harder to use these than using twonship/range/section - every online mapping service that you could care to use will work best with lat/long.)

And we're talking about future-proofing our data here.

Of course we would want to display on our labels a nice name of where it came from, instead of just coordinates, but scientifically it's redundant if we have the accurate Lat/Long!

"Hopefully, mine names and geographic locations will not go out of style." - they may not go out of style, but they have a nasty habit of changing and promoters always liked to use famous mine names (and how many Lost Spanish mines are there in the SW?). Lat/long don't unless you use a different datum, but it will still put you in the neighborhood.

The following is the type description for danburite, trying to pin down where exactly Whites factory was is a bit of a bear.

The mineral here described, I found upwards· of two years

ago, while engaged. in the geological survey of Connecticut. .It

was collected in the town or Danbury near the manufactory of

Col. WHITE, and occurred in small masses of a delicate bluish

white and highly crystalline, feldspar, found among fragments of

dolomite, coming from a bed in place near the mills.

Note that Mindat's own locality database refers to locality names- not latitude and longitude. - but we do put lat/long in where we can.

Noticed that on the Great Basin website, it has not been updated since Nov. 2009???

No call back from Mr. Kleine.

Hello all! I am sorry that I have been so hard to get a hold of. Just having too much fun out in the field! Lots of Projects. Anyway, my e-mail is working again, as is my phone number. I will try and update my website this Spring. The answer to the long-asked question that started this thread- The specimen sounds like it is an Endlichite on Descloizite from Chalk Mountain, Churchill County, Nevada. See you in Tucson!

It's me again. I was able to open the pictures of the specimen in question and realized that it is NOT a Chalk Mountain piece. It is an old and unusual specimen and I will have to do some research and ask some friends. I will answer back soon.
