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.

For the 49th year once again the Mu­nich Min­er­al Show was held. A few years ago un­der the old lead­er­ship the mot­to al­most en­tire­ly stood un­der the theme of min­er­als and fos­sils.

This year not only the name seems to change away from the "Munich Mineral Show" changing to "The Munich Show". The new exhibition management, led by the young Mr. Keilmann seems not quite knowing where to go or has something bigger in mind. One can imagine something in "Munich Mineral Days", it is difficult in the name "The Munich Show". The new show management seems to leave the common way, to keep all options open with a new name. - A comment and fair report written in german language by Stefan Schorn

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“garnet group” does not have its meaning anymore and the intermediate working term “Garnet superstructural group” has been replaced by “Garnet Supergroup”.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.

Für die hier vorgestellte Untersuchung wurden Spektren von Uranophan, Sklodowskit und Uranocircit aus der Literatur herangezogen. Bei den untersuchten Mineralien wurde nämlich festgestellt, dass auf dem gleichen Stück auftretende, andere Uranyl-Mineralien, die Messung verfälschen können, wenn deren Lumineszenz nicht räumlich sicher abgeblockt werden kann. Beispielsweise beeinflusste in einer ersten Messung die vergleichsweise starke Lumineszenz von Uranocircit die Messung an einer Uranophan-Probe aus Menzenschwand. Aus diesem Grund ist es sinnvoll, die Spektren weiterer potentiell auftretender Mineralien wie Uranocircit mit in die Untersuchung aufzunehmen, um bei der Bestimmung der Mineralien solche Einflüsse aufspüren zu können...

Die Mine zieht sich dabei über mehrere hundert Meter entlang des Berges in die Höhe. Sie befindet sich im "Cordillera Quimsa Cruz" (Aymara-Sprache) oder "Kimsa Krus" (Quechua-Sprache) oder auch "Tres Cruces" (deutsch "drei Kreuze") genanntem Gebirgszug im Departamento La Paz. Zahlreiche Stolleneingänge und meist verfallene Bergwerksbauten zeugen von einer umfangreichen Bergbautätigkeit. Verschiedene Quellen schreiben auch von Araca Mine, der Name sei quasi austauschbar. Hierbei handelt es sich um einen historischen Namen.
