Mineralienatlas (name for mineral atlas) is the platform for people interested in mineralogy, geology, palaeontology and mining since 2001. We operate a significant database for minerals, fossils, rocks and their localities. Mineralienatlas is not limited to a section. We bring together information and inform comprehensive.

To complete our information constantly, we need your support. With us, everyone can and should participate. Currently Mineralienatlas is used and expanded by 10458 members. Every month hundreds of thousands of visitors use our website as an information source.

Schon die alten Ägypter seit der 4. Dynastie, Perser und die Römer verwendeten das pulverisierte Mineral als Augenschminke. Im China der Sung- und Ming-Dynastien, in der Ukiyo-e-Schule Japans, im präkolumbianischen Südwesten der heutigen USA sowie während des europäischen Mittelalters und der Renaissance wurde Azurit als wertvolles blaues Pigment in der Malerei und für Handschriften bzw. Miniaturen benutzt. Die blaue Farbe war im Okzident lange Zeit das bevorzugte Pigment, den Kleidern der Jungfrau Maria ihre blaue Farbe zu geben, bzw. Skulpturen zu bemalen. Da der exotische Lapis Lazuli als Pigment Ultramarin weitaus begehrter, aber auch dementsprechend teurer war, wurde Azurit gewöhnlich als Grundfarbe benutzt und Ultramarin nur hauchdünn ...

Die Aufschlüsse in dem Schacht waren extrem metallarm und daher Einstellung der Tätigkeiten. Um 1700 bereits der erste Flußspatabbau. Die „Smaragde“ von Bach (und von Donaustauf) machten Schlagzeilen. 1702 Probeschürfe auf den Gang auf Eisen und Silber. 1703 legten erfahrene Bergleute aus Bodenwöhr und vom Rauschenberg das Schönfärbige Bergwerk mit dem "St. Barbarastollen" und dem "Dreifaltigkeitsstollen am Sandspach" (Länge 38,9 m) an, ohne jedoch auf Metallerze zu stoßen. 1704 nach Einmarsch kaiserlicher Truppen brachte diesen staatlichen Bergbau zum Erliegen...

The metal and its alloys have been used for thousands of years. Copper was first used in coins and ornaments starting about 8000 B.C., and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as сyprium (metal of Cyprus), later shortened to сuprum.

The discovery that copper alloyed with tin produces bronze marked the beginning of the Bronze Age at about 3000 B.C.
Copper is easily stretched, molded, and shaped; is resistant to corrosion; and conducts heat and electricity efficiently. As a result, copper was important to early humans and continues to be a material of choice for a variety of domestic, industrial, and high-technology applications today.

Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite and malachite and have been widely used historically as pigments. ... a contribution by Peter Seroka

Among mineral collectors the mine is famous as well for its unique Pycnite deposit, a variety of topaz occurring in massive columnar aggregates up to a length of 30 cm.

The mining started in 1440 and continued, with several ups and downs and some total shut-down periods, until 1991. The mining activities aimed for a plutonic granite body (350 to 400 metre in diameter and hydrothermally mineralized mainly with cassiterite and smaller amounts of wolframite, molybdenite, arsenopyrite, bismuth and others) and managed to extract a total sum of 37 million tons of ore. The huge surface break, called "The Altenberger Pinge", is the result of several roof collapses caused by excessive ore excavation and later on the continued drawing of caved material from the bottom of the fracture zone.

Collectible minerals were rare and small, so the Altenberg tin mine became never as famous as the Freiberg or Ehrenfriedersdorf districts, but its unique geology and mining technology made it quite interesting and worth a closer look.
