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.

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...

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...

Ich verbrachte sie hauptsächlich im schweizerischen Binntal, wo ich bei dem einheimischen Strahler Andre Gorsatt quasi „ in die Lehre gehen“ durfte. Ich reinigte und formatierte Fundstücke, begleitete zuerst die Strahlerexkursionen, die Andre Gorsatt anbot und durfte in Folge auch eigene Führungen leiten. Es mag an meinem Habitus von einem Drittel Athlet und zwei Dritteln Pykniker gelegen haben, dass ich in der Hauptsache für die Familien- und Senioren-Führungen vorgesehen wurde...

Im Grunde genommen gibt es für Siderit keine eigene Geschichte, es sei denn, man erforscht sie mit einem interdisziplinären Ansatz im Zusammenspiel von Ethnologen, Montanhistorikern, Geologen und Ingenieuren. Ein Mineralienportrait geschrieben von Peter Seroka

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.

Olivine is not a se­parate min­er­al, but a mem­ber be­long­ing to the fors­terite-fay­alite mix­ing se­ries. Olivine be­longs to the olivin-groupe whose end-mem­bers are cal­cio-olivine and tephroite. Fors­terite is a mag­ne­si­um sil­i­cate; fay­alite an iron sil­i­cate. If com­mon­ly is spo­ken of olivine, it is usu­al­ly ... moreOlivine is not a separate mineral, but a member belonging to the forsterite-fayalite mixing series. Olivine belongs to the olivin-groupe whose end-members are calcio-olivine and tephroite. Forsterite is a magnesium silicate; fayalite an iron silicate. If commonly is spoken of olivine, it is usually a more or less iron-rich forsterite. The color of olivine is generally yellowish green, olive green to black. You will find much more interesting details in our portrait about this common mineral series.

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)
