This Land does not have, by a long way, such a diversity of minerals as its southern neighbor Saxony, but its parts of the Harz Mountains were the source for some highly-desired mineral classics, first and foremost the legendary specimens of galena on siderite from Neudorf - that today are among the most expensive German minerals on the market.

What else is to mention? The Mansfeld basin with its excellent silver samples, betechtinite, maucherite, nickeline... And, of course, for the systematic lovers all the rare salt minerals with their many type localities in that Land.

Fluorite and siderite from Harz Mountains, possibly Grube Louise near Rottleberolde. Ex Sorbonne and Herb Obodda collections.

Hello,
these siderite crystals in combination with white/colourless fluorite are typical for Stolberg (Luise mine). The location is always mixed up with Rottleberode, but there are two fluorite occurences. Rottleberode (Flußschacht mine) and Stolberg (Luise mine). What makes the whole thing more complicated is that one can often see typical green Rottleberode specimens marked "Luise mine" or vice versa. The classic Stolberg fluorites are sought after. The green Rottleberode fluorites 10 or 15 years ago were kind of a mineralogical off the shelf article. Today it´s hard to find a really good, undamaged specimen.
Best regards
Andreas

Hello Andreas,
Thank you for the information. It is difficult to find good information on German locations in English language. Mindat lists Luise Mine as being Rottleberode.

Hence it is a little bit confusing. I had to look it up... but it´s one district indeed, called Stolberg-Rottleberode. There are two veins, the Flußschächter/Backöfner vein (Rottleberode) and the Silberbach-Louiser vein (Stolberg). Silberbach was a known locale for huge baryte samples. The two shown fluorite/siderite specimens come from the Louise mine (Stolberg). The "classic stuff", i.e. the big sea-green fluorite crystals were found in the 1950s in the Backöfner vein, 2nd level, Flußschacht mine (Rottleberode). Here´s a smaller sample from Flußschacht mine.

Another specimen from Neudorf. The largest galena is about 1.5 cm, the largest siderite 0.7 cm on edge and the largest calcite crystal 0.5 cm on edge.
Unfortunately I have no other clue about the exact mine it came from as the old label only states "Neudorf". If any of you have any idea about the mine it could have come from, I would be glad to get details through PM. Thanks.

Thanks. | I chose this way instead of PM because we want to share this mineralogical trip through Germany together with all its information:
Those typical combinations of galena and siderite are most likely from Grube Pfaffenberg, https://www.mindat.org/loc-21614.html
Very nice specimen, by the way :)
