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.

Der Begriff Karst steht für die Gesamtheit der Formen von durchlässigen, wasserlöslichen Gesteinen (z.B. Kalkstein, Gips, Salze), die durch Oberflächen- und Grundwasser ausgelaugt werden. Als verkarstende Gesteine gelten in der Reihenfolge ihre Löslichkeit Salze (Anhydrit, Gips, Kalk- und Quarzgesteine (Sandstein, Quarzite)). Durch Lösungsvorgänge kommt es zu charakteristischen Karsterscheinungen. An der Oberfläche sind dies z.B. Karren (Schratten), Dolinen, Uvalas, Poljen, Schlotten, Erdorgeln. Zu den unterirdischen Karsterscheinungen gehören oft weit verzweigte Höhlen und die typischen Erscheinungen der Karsthydrographie: unterirdische Flussläufe und Karstseen, Karstquellen, die unter ... ein Beitrag von Peter Seroka

Begleitet wird der Hauptgang von einigen ins Liegende ablaufende, bogenförmige Nebentrümer, auf denen u.a. die Grube Alter Theuerdank gebaut hat. Über Tage ist der Ausbiss an Pingen und Schürflöchern gut zu erkennen. Wie Harnischflächen belegen, stellt der Reiche Troster Gang eine Abschiebung dar, wobei die hangende Scholle mit einem Versatzbetrag von wenigen Metern abgesunken ist. Er kann als eine diagonale Verbindung ("Diagonaltrum") zwischen dem Wennsglücker Gang im Norden und dem St. Jacobsglücker Gang im Süden aufgefasst werden....

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.

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.
