An almost forgotten variety of dolomite is "tharandite" in brown translucent rhombic crystals, quite unusual for this mineral. Sometimes you see "normal" dolomite, typically saddle-shaped crystals falsely labeled as "tharandite". These specimens occur from the newer lime quarries at Tharandt near Dresden, Saxony. The shown sample is an original "tharandite" from its type locality, the Schweinsdorf lime quarry near Döhlen.

Three elbaite micros (the two upper ones with lepidolite) from Wolkenburg, Saxony. The tourmalines from this famous classic locality ranged from black, blue, green to red and even white. Furthermore crystals occured, green on the one and red on the other end of the crystal. The little crystal in front measures about 1 cm in length.

Hi, Ed, if you read this: you asked Tobias for some fluorites from seldom shown German localities - as a starter the four of them for you. Beginning with a corroded crystal (6 cm) from the Stecklenberg quarry, Stecklenburg near Thale, Harz. In this quarry a find was made about the year 1900 which contained beautiful pale violet fluorite crystals arranged with black schorl, apatite and smoky quartz. If you come to Berlin one day you can see a sample in the Naturkundemuseum which is much better than the shown one;-). But nevertheless I am proud of possessing a fluorite from Stecklenberg... It comes from the Berlin collection of Fritz Seliger. This man has been the gem prospector in order of the German Emperor!

Good yellow fluorites come from the Hilfe Gottes mine near Memmendorf, Freiberg district, Erzgebirge, Sachsen. The pic shows a 12 cm wide specimen with little pyrite on quartz.

They occur also at the border between the "Granulitgebirge" and the Freiberg mining district, Saxony. That´s where this specimen comes from: the Alte Augustus Stolln, Hasensprung near Rosswein. Samples like this (and from other localities like Schönborn-Dreiwerden too) are looked for and very rare. The cubes on this sample measure up to 1 cm and are accompanied with some baryte.

Here you have a really unusual locality: pale green cubes from the Lieth lime quarry, Elmshorn near Hamburg. This locality is the only outcrop of the Perm decade in northern Germany. Here copper shists are found laying over "Zechstein"-gypsum. In this copper shist you have sometimes fluorite cubes but good specimens are rare.

And some more...


Dolomitpseudo (Freiberg).JPG
 Description:
This dolomite pseudo is definitely a favourite of mine. You know these pseudos after calcite scalenohedrons very well from the Schlema district, Erzgebirge, Saxony. But - this one is from Freiberg, precisely from the Abraham Shaft. It comes from a miner collection and was collected in the 1920s. It is the first one I ever saw from Freiberg and I think it will be the last...

Calcit (Bad Freienwalde).jpg
 Description:
Another good locality in Brandenburg are the claypits around Bad Freienwalde, some 80 km in the east of Berlin. There come very good gypsum samples, occuring in christmas tree-like aggregates up to 40 cm. From the northern claypit is this cute specimen with greenish calcite on lime stone.

Although Berlin and Brandenburg are not even blessed with mineral deposits we have... amber! At some places masses of them but deep in the ground;-) Sometimes they raise up to daylight like this classic specimen (about 7 cm in width) from the gravel pit at the Pinnower Bernsteinsee (amber lake, sic!) near Velten, Brandenburg.

Flint (Segeberg).JPG

Another mineral which is widespread in northern Germany is flintstone. Some collectors do not understand why to pick up that stuff... But if they are as pretty as the shown zebra-like stone from the Segeberg forest near Bad Segeberg, Schleswig-Holstein it is worth it, I would say. 10 cm sample from a 1975 find.

Galenit (Freiberg Rote Grube).JPG

This 5 cm wide sample with corroded galenite crystals is from Freiberg too but not that old as the above shown dolomite. It comes from a little new find at the Rote Grube in the very "city center" of Freiberg. The find contained I think some ten specimens and the sample looks forward to become a classic rarity one day.

They are mentioned in the famous mineralogical lexicon of the saxonian localities by August Frenzel (1874).

Thanks, Andreas. Your systematic but also aesthetic collection is exhaustive. I have had a very good time watching it. Go on, please. Man does not live by "killer specimens" alone.

The best the labels and the history behind the pieces.

Cheers,
Antonio

I agree with Antonio. I know Andreas' style of collecting and specimens from his collection for several years now, and i really admire the accuracy with which he is devoted to historical specimens from German localites. And his care for old (sometimes REALLY old) labels make his collection a commendable mixture of both mineralogy and history.

So please go on, Andreas, and "bother" us with more ;-)

Glückauf!

You want them, you´ll get them. Here´s the second package for you;-)


Fluorit (Neudorf).JPG
 Description:
A nice galena from Neudorf/Harz is hard to get, though. Nevertheless I´d say that getting a good fluorite from there is even harder. I bought this specimen with the declaration "Schönbrunn, Voigtland". But in fact it is an old classic from Neudorf with typical siderite and quartz crystals on the pale blue cubes as well as some sphalerite and galena in the shist matrix. Former collection of Bergdirector Geipel/Eisleben, dating from 1921 (without label, unfortunately). The cubes measure up to 2,5 cm.

Vivianit (Waldsassen).JPG
 Description:
Where do good vivianites come from? Trepca, yes. Bolivia, yes. Germany... Germany? Yes!! There is a locality in Bavaria, the Bayerland mine near Waldsassen, Fichtelgebirge. This mine gave crystals up to 10 cm in pyrrhotite. Normally the bigger ones (5 cm and more) are rather irregular but this one (more than 9 cm!) isn´t. I would say it´s the best piece of my collection!

Rhodochrosit (Kleinvoigtsberg).JPG
 Description:
If you like Sweet Home mine rhodochrosites you´ll smile at me if I tell you that this is a very good Saxonian rhodochrosite sample. About 6,5 cm consisting of tiny saddle-shaped rhombs. From Alte Hoffnung Gottes mine, Kleinvoigtsberg, Freiberg district, Erzgebirge, Saxony. Rhodochrosite for itself is not that rare in Freiberg, but crystals are. Kleinvoigtsberg and Rothenfurth developed the best ones. Today it´s very hard to find any, this one I got at the Freiberg show in 2009. With two old labels (dating from 1901) - "Dialogit" is an old German name for rhodochrosite (being in use until approx. 1920).
