Barite is known here in two generations. Older generation forms tabular, mostly grey crystals more than 10 cm large in some cases. But higher in quality were up to 10 cm large "coffin" formed crystals of the younger barite generation. Usualy were of yellow, grey and bluish colour. The highest quality specimens came from Anna shaft - (Jánská and Eusebi vein), Ševčín shaft (Mučednická vein) and Lill shaft (Upper black pits vein).
Well known is the Sádek shaft, because of the barite occurence, where were found especially crystals of its older generation up to 15 cm large. Its crystals from this occurence are very often partly covered by younger dolomite crystals.
Uranium and base-metal district did not provide many high quality samples, rare specimens of nice small tabular barites came from the Bytíz ore node.
Large barite found is known from the Vrančice deposit, where occured large barite cavity with more than 10 cm brown barite crystals. The largest saved sample is more than 1 m large full of tabular barite crystals and it is the part of mineralogical collection of the Mining Museum Příbram today.]]> Pavel Skacha Best Minerals - Barite Wed, 22 Aug 2012 12:11:20 +0000 http://www.mindat.org/forum.php?read,94,137209,269089#msg-269089 http://www.mindat.org/forum.php?read,94,137209,269089#msg-269089 Until recent times were good known specimens caming from quarry near Lahošť.

Hello,

I have purchased a nice specimen of Baryte-crystals on matrix (Dolomite) from Miraflores/Peru. An associated and well micro-crystallized mineral with fatty metallic lustre is labeled as Hematite. This is probably right, but the crystals have an untypical habit, and show a lustre that is not that of fresh Hematite. There occur cherry-red internal reflexes in the greater crystals (not untypical for Hematite). The crystal habit und the fatty lustre lead to the hypothesis, that the xls consists eventually not of Hematite but rather of Pyrargyrite. Are you familiar with ore minerals from Miraflores? I would like to exclude or confirm the hypothesis "Pyrargyrite". I think, with a probality of ca. 90% this mineral is in fact Hematite.

Thank you,

As I have already told Bill per PM, the barite specimen from the Black Forest is from Münstertal Valley, most likely Teufelsgrund Mine. Wieden could be another possibility.

I would encourage you to keep an open mind about great micro images and to include a few if you feel they are truly outstanding. Take a look at the German hematites from Rhineland-Palatinate, Eifel Mts, Polch, Ochtendung, Wannenköpfe and I think you will agree that though these hematites are micros they are worthy of inclusion.

I don't mind if you show images of 20 good ones from a particularly good locality especially if there is a good range of associated minerals with some of them. If a guy goes collecting at a locality that produces decent barite crystals he should be able to come to the Best Mineral barite article for that country/state/etc and be able to compare his collected specimens to the best examples that we have in the database. Of course since Baryte is a common mineral there will be some localities that produce micro or only very poor Baryte that we may wish to exclude, but I am willing to let our authors decide what the cut off point is. Not all minerals shown here need to be world class by any means, and even some exceptional images of micro barites can be included it they strike your fancy.

I would advise sticking with the alphabetical listing for states, because many foreign users are not familiar with just where various states are in the United States, and even those that are may not be very clear on just exactly which states are considered Western or Midwestern, Eastern or Northeastern etc.]]> Rock Currier Best Minerals - Barite Sun, 20 Feb 2011 08:01:02 +0000
