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 10530 members. Every month hundreds of thousands of visitors use our website as an information source.

REE belong to the most important raw materials of the 21st century, which are used in a large number of key technologies. However, due to the fact that almost 97% of the world's REE are mined and produced in China, REE have become an ongoing political issue, mainly amongst technology providing countries like the US, Japan and Western Europe.

This portrait tries to explain the characteristics of REE and their role for our modern world. Written and investigated by Peter Seroka. (Article in german)

1908 wird in einem Bericht, der im Mai verfaßt wurde, und von Max Priehäußer, München stammt, zu diesem Zeitpunkt keine Bergbautätigkeiten erwähnt. Der Gang wurde aber über Tage, wie der davorliegende später so genannte Herminegang, ebenfalls übertägig und später auch mittels eines Stollens und zumindest zweier Tagesschächte abgebaut. Die beiden Tagesschächte lagen im Südostfeld und hatten ihren Schachtansatzpunkt bei 391,6 m NN und bei 389,2 m NN.

1923 - 1930 sind die Angaben zu Grube Erika sehr verwirrend. In dem Zeitraum werden mehrere Besitzer genannt. Der Grube läuft vermutlich unter dem Namen Grube Lanzenleite.

1923 erwerben der Gutsbesitzer Hans Schanderl aus Paulsdorf und Ing. Thurm aus Amberg die Ausbeuterechte der PlanNr. 2004 und 2005 in der Lanzenleite vom Bauern Nikolaus Harrer in Säulnhof. Sie stellen Maschinen auf und teufen damit einen Förderschacht ( siehe Skizze lfdNr. 8 ) bis auf 20 m ab... Ein Bericht von Michael Kommer

Calcite is one of the most abun­dant na­t­u­ral min­er­als. It is found in very dif­fer­ent shapes, both com­pact as lime­s­tone as well as sin­ter in caves and in the crys­tal­line state.

It is found in very different shapes, both compact as limestone as well as sinter in caves and in the crystalline state. But even in our daily life calcite is always present: in some regions it blockes water pipes as "chalk", we build our houses with it, it is in our food chain and without it we could not stand upright.

Calcite is not rare, but the varied mineral on Earth. The variety of forms and variations of the forms of calcite are unmatched in the world of mineralogy. By 2009, more than 800 Calcit forms have been described.

Many dealers were extremely satisfied. According to the organizer, 18,000 guests visited the halls on Saturday alone. Both days were a hive of activity and the numerous children's attractions were well received. Parents were everywhere with their children to complete the geo-rally.

For mineral collectors, the usual dealers were on site, although some tables remained empty. There were no highlights from the scene or overflowing tables with identical material from new finds. However, one stand with an impressive selection of Germanite chunks was a welcome novelty.

The special exhibition “The Impossible Crystal” was a success. Even if not all the exhibits could be described as “impossible crystal”, all the pieces were of the best quality and well worth seeing. In the B halls, the author visited the “Young Designers”, including a student who presented cast silver jewelry in an organic design that showed off the embedded stones to their best advantage - an impressive piece of work...
