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 10531 members. Every month hundreds of thousands of visitors use our website as an information source.

Durch die großen Wintersportereignisse - Eisschnelllauf in Inzell, Biathlon in Ruhpolding -, aber auch durch das Skigebiet Winkelmoosalm - von Ruhpolding kommend auf dem Weg zum Parkplatz Seegatterl fährt man am Rauschberg vorbei - haben die östlichen Chiemgauer Alpen einen überregionalen Bekanntheitsgrad gewonnen.

Dabei hat diese Ecke der Alpen auch eine ganz andere Tradition. Über Jahrhunderte - grob von der Mitte des 16. Jh. bis in die Anfänge des 20. Jh. - wurde hier Bergbau betrieben, und das Metall auch weiterverarbeitet. Die großen Wälder dienten der Holzproduktion für diesen Bergbau und für die Salinen in Traunstein und Bad Reichenhall ... ein Beirag von Martin Stark

Die alten Chinesen konnten schon seit der Steinzeit feine Keramik herstellen. Während der Chou-Dynastie (1122 - 255 v.Chr.) wurde im Gebiet um Sha-Hsing (Provinz Chekiang, einem Teil des damaligen Staates Yüeh) graue bis olivgraue, bei hohen Temperaturen gebrannte Keramik entwickelt, welche unter dem Namen Yüeh (oder Yüeh-Yao) bekannt und berühmt wurde. Diese Keramikgegenstände waren mit einer gelblichgrünen oder graugrünen Glasur aus Feldspat überzogen, welche als Vorläufer der bis heute hoch geschätzten Celadon-Keramik gilt. Fast 1.500 Jahre später wurden in der Sui-Periode (600 n.Chr.) erste Keramiken aus meist unglasiertem Kaolin produziert. Wenige Zeit später während der T'ang-Dynastie (618 - 907 n.Chr.) wurden Methoden ... Ein Beitrag von Peter Seroka

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...

Min­er­al por­trait gar­netThis portrait mainly deals with the 6 classic garnets, their amazing history, the world’s best known classic and modern localities and deposits and their use as a gems or abrasives. It also deals with the common belief related to the non-existence of blue garnets and its refutation proven by new finds. A separate chapter deals with synthetic garnets. But it also deals with the mix up of definitions, groupings and old and unnecessary terms, which have finally been terminated or brought to a common denominator.

In 2012 the IMA (CNMNC) has defined garnets as members of the Garnet Supergroup, which include all minerals isostructural with garnet regardless of what elements occupy the four atomic sites; i.e. the supergroup includes several chemical classes . Those minerals are closely related to each other and may form a series with each other. Some garnets form intermediary minerals between each member, and may even be intergrown within a single crystal.

With the publication of the new nomenclature of the garnet supergroup, the term “garnet group” does not have its meaning anymore and the intermediate working term “Garnet superstructural group” has been replaced by “Garnet Supergroup”.
There are 32 approved species and 5 “candidate” species waiting on approval. The 32 species are subdivided by their Z-charge into 29 species, which belong to 5 groups and to 3 single representative species.
One of those 5 groups is the “Garnet group”, consisting of the 6 former (classic) garnets Pyrope, Grossular, Spessartine, Almandine, Uvarovite and Andradite plus 8 rarer garnets , as Menzerite-(Y), Eringaite, Goldmanite, Momoiite, Knorringite, Calderite, Majorite and Morimotoite.

De­posits are one of the most im­por­tant top­ics in ge­ol­o­gy. Peter Sero­ka has ad­dressed the is­sue in sev­er­al years of work and has writ­ten an up-to-date ge­o­log­i­cal sum­mary.

Peter Seroka has addressed the issue in several years of work and has written an up-to-date geological summary. He dedicated his work to the 15 th anniversary of Mineralienatlas. The work gives detailed information regarding the origin of deposits, the different types of deposits and their classification. Examples of economically important deposits complete the chapters. Provided that this comprehensive work would be printed it would be a volume of over 400 pages; here it is provided in its entirety, online. Thanks to Peter Seroka. (written in german language).

Emeralds, aquamarines, heliodors and morganites were and are used for the manufacture of jewelry because of their beauty. The common beryl is the main source of the metal beryllium; 80 % of beryllium ore is mined in the United States. The largest known crystal reached a length of 18 m.

This lavishly researched and very comprehensive portrait by the author Peter Seroka relates to history, name origin, causes of color, occurrences , paragenesis and the use of this mineral and its varieties. Subchapters with numerous photographs and drawings deal with the extraordinary beauty of the mineral. Each chapter itself is a separate portrait of a distinctive variety and its characteristics, occurrences, use and history.
