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 10586 members. Every month hundreds of thousands of visitors use our website as an information source.

Das waren: Grube Max, Grube Hanns und die Aufschlußgrube Lissenthan. Bedeutet das nicht alle Stufen die den Namen Johannesschacht tragen auch aus dieser Grube stammen. Angebote sollten kritisch hinterfragt werden.
Stufen die auf Halde gefunden wurden oder im über Tage Bereich bekommen als Fundortbezeichnung "Halde der Grube Johannesschacht" oder "über Tage Fund Grube Johannesschacht", u.U. noch mit einem entsprechenden Hinweis.
1929 wird erwähnt, daß bis zu einer Teufe von 28 Meter grobspätiger Stinkspat vorgefunden wurde. Uranmineralien wurden erst ab einer Teufe von 18 m angetroffen.
1931 wurde Stinkspat in Würfeln, Oktaedern, Rhombendodekaedern sowie... Ein Beitrag von Michael Kommer

The former "Eisen­ham­mer" (iron ham­mer) to He­im­buchen­thal has to show a very in­ter­est­ing his­to­ry.

The hammer mill established at the beginning of the 18th century reached at the end of the 18th century in the possession of the family Rexroth under whose guidance the company came to the full blossom. The squires showed a high social engagement which was reflected in the reimbursement of the workers, but also in the enlargement of the entrance ways. In specially constructed schools up to 30 children were teaches on the hammer mill property. On one, from oaks surrounded cemetery the late squires and their members were buried. In 1891 the company was discontinued and the hammer mill was converted into a court estate. From the industrial monument all buildings except the great smithy are even today in a very good state.

One of Mada­gas­car's ge­o­log­i­cal spe­cial­ties are the so-called Ts­in­gy: bizarre, at first sight hos­tile Karst land­s­capes, though form, due to the in­ac­ces­si­bil­i­ty, a refu­gial area for some spe­cies. The word Ts­in­gy means "walk­ing one tip-toes" or "where one can­not walk bare-foot" in Mala­gasy lan­guage, an ... moreOne of Madagascar's geological specialties are the so-called Tsingy: bizarre, at first sight hostile Karst landscapes, though form, due to the inaccessibility, a refugial area for some species. The word Tsingy means "walking one tip-toes" or "where one cannot walk bare-foot" in Malagasy language, an accurate description for the partially razor-sharp rock formations which can reach 20 m in height and with ends which can be as thin as pencils.

Best known and most impressive are the Tsingy of Bemaraha in the West of the island and the Tsingy of Ankarana in the North, both widespread Karst areas. In the North, as well, about 10 km south of the city of Antsiranana, one can find the Red Tsingy which have been washed out of the lateritic layer of earth.

Ti­tanit ist ein Min­er­al, welch­es man in Vorkom­men un­ter­schiedlich­er Ge­nese an­trifft. In Granit­peg­matiten kön­nen Kris­talle bis 25 cm groß wer­den; in Al­ka­ligestei­nen bis zu 6 cm. Kris­talle von er­stk­las­siger Qual­ität (rel­a­tiv auch Edel­stein­qual­ität) fin­d­et man je­doch nur in alpino­typen Klüften.

Kristalle von erstklassiger Qualität (relativ auch Edelsteinqualität) findet man jedoch nur in alpinotypen Klüften. Erstmals gefunden wurde Titanit 1795 in den Hauzenberger Graphitgruben im Bayerischen Wald und beschrieben durch Martin Heinrich KLAPROTH, der das Mineral nach seinem Gehalt an Titan benannte. Soweit nachvollziehbar, führte KLAPROTH die Erz-Analysen im Auftrag eines Bergbauunternehmens durch.

In the Republic South Africa the trip led to the copper mining region of Okiep as well as the lead zinc mines of Aggeneys and, finally, to the Kalahari manganese ore districts of Postmasburg and Kuruman.
