I agree - alphabetical locality order the way you are doing it currently is the best option.

Ron,
Thanks for the suggestion. It certainly is good enough to go into the best minerals article. This articles needed a rework and a little TLC which I gave it and you picture is now there.

Dear Rock,

About the occurence of Alabandite in Garpenberg Norra;
The associated minerals together with the alabandite crystals on calcite crystals are pyrrhotite, asphaltum, pyrite(?), and cubanite but NOT rambergite. As far as I know- most of this material came from deep levels~800 m (my own selfcollected are from 790).

Rambergite occurs in small cavities together with fluorite, apofyllite, calcite, barite, sphalerite, galena, samsonite, pyrargyrite, pyrrhotite and small amounts of freibergite. ( transl from summary descr: [www.nrm.se]). The 2 Rambergite crystals I have occur in a diopside-rhodo skarn.

The phrase "and the management put some of the material out on the dump for collectors to collect" is somewhat imprecise. The dumps was created as an intermediate storage for the mine, not intended for collectors but the management did allow collecting if one asked for permission.


Best regards

Fernando, some of them might make it into best minerals, but they would first have to be uploaded to our mineral gallery.

The small black xls on the lead Alabandite photo are manganoquadratite [rruff.info]

There's a good story about this specimen. I'll try to get permission to tell it

Bob,
Which specimen are you talking about? The one that heads the article?

Hi Rock,

People are touting the new Alabandites from Merelani Hills (Mererani), Lelatema Mts, Simanjiro District, Manyara Region, Tanzania as being potentially world class. see [www.mindat.org]

And allow me the opportunity to profoundly thank you for all the work you do in the "Best of" Dungeon. It is an indispensible resource that I refer to weekly.

Cheers,
Jeff

Jeff,
Thanks for the kind words. That alabandite is worthy of inclusion in the article and Ill put it there. Did you take the picture? If I may suggest, next time stop your camera down to F22 or 35 if you can. That way more of the image will be in focus. Also you might try taking the picture on a lighter background so that the mineral outline will stand out a little more. You can also often do this in photoshop if you fiddle around with it.
