LocalitiesBärenbad Mine, Scharnbachgraben, Hollersbach im Pinzgau, Zell am See District, Salzburg, Austria

I find it odd that there are 11 photos of "eclarite" like minerals on Mindat and 10 of these are of eclarite . Since there are 5 minerals (cosalite,eclarite,galenobismuthite,gladite,lillianite) found there that look the same ( same cleavage, same color, same habit, same hardness) and no analysis I suspect that this is more wishfull thinking than fact. Is there actually anything visually distinctive about the eclarite at this locality? Any distinctive assoc. minerals or rock?

Actually if you read the description for the species http://rruff.info/uploads/AM70_214.pdf only this one http://www.mindat.org/photo-206851.html seems to fit that. "As fan-shaped aggregates of acicular crystals" . The other mode is " as granular fracture-fillings in pyrite and arsenopyrite" is not represented in any of the photos.

A lot of well-studied eclarite material (found by Prof. Paar) was on the market.

In polished section one can find not only eclarite, but also various other sulphosalts.

I am not questioning whether or not eclarite was found there just the photos on Mindat. "also various other sulphosalts." therein is the problem.

I`m absolute on your side Reiner!

Similiar to the aschamalmite - most of them is cosalite.

Hello Cristian,

In your work with this material how common was the eclarite compared to the other similiar looking minerals such as coasalite?

Reiner, I had no time to check this specimen myself but it's swapped from a student of Prof.Paar (mentioned by Uwe above). We have several hand sized specimen of sulfosalts from there in our collection and hopefully I can check some in the future. Talking about the aschamalmite: I checked several of them by thin sections and they all were cosalite. I assume aschamalmite is rarer than expected by some dealers.

Why is aschamalmite not listed as a mineral found there?

14th Feb 2016 06:31 UTCChristian Auer 🌟 Expert

Because it wasn't found there. I mentioned it as another similar species from Salzburg that is often wrong labeled.

The well-studied eclarite material I mentioned has eclarite as the dominant sulphosalt; this was confirmed by Dan Topa who did the original microprobe analyses.
