Material from Borneo commonly has Arsenic present also - mostly as spherical structures.

The numeros quarries an mines in Italy produce similar structure and disolution characteristics though usely with antimony oxides present.

Other locations are posible of course.

Without the specimen in hand can only suggest a more probable location.

PM me if I can be of any additional help with regard to Stibnite localites.

The last photo is of a specimen from my collection. It was purchased from a dealer at a small mineral show in Minnesota several years ago. The original label (now lost, unfortunately) only gave the locality as "Iyo, Japan". I questioned the dealer, as it seemed a little too good to be true (the piece only cost $30US - I traded an Indian stilbite for half of it). Now I'm really curious.

Rob, why do you suggest that Borneo might be the correct locality? Any information you can provide will be greatly appreciated. It doesn't look like anything I've seen from Italy.

You can find the Gwindel page here: [www.mindat.org]
It is listed as plain Gwindel and not "Quartz (var: Gwindel)" because it's not really a variety but rather the Swiss Strahler's name for twisted quartz.

I've just transferred in a bit more data for gallite from the 'Handbook' and from the original Amer. Mineral. new mineral abstract. But I note that whereas the Handbook and Dana 8th edition both give the type locality as Tsumeb, we have listed Kipushi. The new mineral abstract mentions both localities, but the authors (Strunz et al.) studied Tsumeb material, while acknowledging that the species had also been reported from Kipushi by Uytenbogaardt, so it looks like Tsumeb is correct. Can we correct, please?]]> Andrew G.

Also the Burrows reference cited has been superseded by: Ontario Dept. of Mines, 1968, MRC No.10, Silver Cobalt Calcite Vein Deposits of Ontario, by A.O.Sergiades everything prior to 1968 should be confirmed by this publication which includes the coordinates ( publication is free online at the Ontario Department of Mines website) .
Furthermore claims should not be entered in the database without coordinates as the names constantly change depending on who it belongs to at the time. Also claims are tracked by claim numbers rather than staker's name and it is only in some publications that the claim holders name is referred to at the time the research was done for the publication.
[www.mindat.org] this is also the same as the Walsh mine and represents the ownership of the original Walsh claims from 1912-24 by Miller Lake Silver Lodes Mining Co.(Hart claims: 135, 136) Like most old mining properties the ownership has changed many times aqnd so have the claim names. In the case of the Walsh mine it has been covered by the following claims

1912: Walsh claims 98 and 3879
1917-18: Crown Reserve Mining Co. held option

We should probably use series names only for material in which the dominant component is unknown, otherwise Mindat could quickly get cluttered up with enormous numbers of series names, and as Pavel pointed out, a single crystal can easily be a "member" of several different series at the same time. Probably better to avoid "series" altogether in complex groups like spinels, garnets, tourmalines and amphiboles and just defer to the group name.]]> Alfredo Petrov Mistakes and Errors Mon, 06 May 2013 03:33:19 +0000 http://www.mindat.org/forum.php?read,7,292753,293174#msg-293174 http://www.mindat.org/forum.php?read,7,292753,293174#msg-293174 There are so many same/similar occurrences world-wide that it is nothing I would ever hazard a guess on for locality, had it been an unlabeled specimen.

There are similar occurrences in my own vicinity which actually occur both along and astride a large serpentinized belt/zone, but still no notable evidence of Cr mineralization within these particular formations as Pavel noted.

For the statistical one place is irrelevant or does not apply because it is a virus or childishness and I agree.
In this case are the most portuguese photographic representations with more than one author and the variable of photo antiquity posted where you can apply a statistical.
