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 10533 members. Every month hundreds of thousands of visitors use our website as an information source.

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

Jh eingestürzten Bergbaus auf Zinn mit den umliegenden Halden (Beran 2006). Diese stammen sowohl aus dem geschichtlichen Bergbau, wie auch aus den Aktivitäten -untertage und übertage- in jüngster Zeit (20. Jh., Einstellung des Betriebs der Stannum 1991, Bergbau auf Wolfram und Zinn).

Auf der Fundstellenseite wird auf einen Beitrag des Förderbvereins der Lithothek verlinkt. Diese haben die Fundstelle in der Lithothek aufgearbeitet.

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.

Das wichtigste Kriterium, um diese beiden Varianten auseinander halten zu können, sind die in der intrusiven Variante vorhandenen, schmalen Zonierungen, welche die blaugrauen Kristalle dünn umschließen. Generell finden sich 2 Arten von Einsprenglingen in der intrusiven Variante: 1. kleine, zerbrochen wirkende rosarote und 2. größere, blaugraue mit schmaler Zonierung, welche die gleiche Farbe aufweist, wie die der Kleineren Einsprenglinge. ...

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.
