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.

Fal­tenEine durch Faltung entstandene Verbiegung oder Verkrümmung einer ehemals horizontal geschichteten Gesteinseinheit in allen Größenordnungen. Je nach Form unterscheidet man Knickfalten, Biegefalten oder Fließfalten. Die Faltenformen Sattel (Antiform) und Mulde (Synform) sind abhängig von der Mächtigkeit des verfalteten Schichtpaketes, den mechanischen Eigenschaften der Gesteine, dem Vorhandensein von Abscherflächen und auftretenden Spannungen.

San José Mine, Oruro, Bo­liviaDo you know El Tio, the ruler of the underworld? In January 2012 Stefan Schorn, administrator of mineralienatlas.de, had the chance to visit the Bolivian San José Mine. In his article he tells us about the history of the mine and shows us with over 60 pictures this adventuresome trip inside the mine. (Article in German)

San Ti­m­o­teo Mine at La Union min­ing area, Mur­cia, SpanienGypsum needels and blue Baryte have made this mine known for mineral collectors. A recent report from Sept. 2012 shows that good finds are still possible. To visit this mine is relatively easy. The evacuation of the gypsum needels on the other hand is more difficult. Unfortunately, vandals have left their mark, but read and see it yourself. A report by Stefan Schorn. (Article in German)

Min­er­al por­trait Baryt (in ger­man)In the late Middle Ages massive amount of Baryt which phosphoresced when it was gently heated, were discovered in Italy. This stone was named after its place of discovery "Pietra fosforica di Bologna" (phosphorescent Bologna stone) and was of great interest to alchemists. Although the name baryte has been assigned centuries later, it may be assumed that the Bologna stone is the first description in the literature. A portrait about this famous mineral by Peter Seroka.

Min­er­al Days in Mu­nich 2012 or „The Mu­nich Show“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

Ge­ol­o­gisch­es Por­trait - Wüste In kulturhistorischer Hinsicht spielte die Wüste seit der Antike eine wichtige Rolle in der europäischen Historiographie und Literatur. Einerseits symbolisierte die Wüste seit Herodot das Fremde und Andersartige, das sich dem europäischen Zugriff entzog. Andererseits bot die Wüste aber auch Rückzugsmöglichkeiten. Insbesondere durch die Bibel (Auszug aus Ägypten der Israeliten, Versuchungen Christi) und die spätere hagiographische Literatur (Eremiten) wurde ein Bild der Wüste nach Europa transportiert, das im Kern bis heute fortwirkt. Durch die Domestizierung des Dromedars gelang es dem Menschen, tiefer in die großen Wüsten vorzudringen und zu durchqueren. Dadurch konnte die Wüste zum Lebensraum des Menschen werden, welchen es gelang, diesen Einöden Lebensunterhalt für sich und ihre Tiere abzugewinnen... Ein Beitrag von Peter Seroka

Public Sci­ence Pro­jects / Sk­lo­dowskite and Bolt­woodite from Lavri­on – an In­ter­est­ing Epi­taxyAt the site Paliokamariza Mine No. 18 (Plaka, Lavrion, Attica, Greece), yellow, needle-like uranium minerals were observed growing on gypsum. Under UV light (365 nm), two distinct fluorescence colors appeared: shorter, thinner needles glowed bright green, while longer, well-formed needles glowed yellow...

This study illustrates a notable epitaxial relationship between Boltwoodite (green luminescent) and Sklodowskite (yellow luminescent) on a gypsum matrix, discovered at Lavrion, Greece. Luminescent differentiation under UV, combined with spectroscopic and EDX analyses, revealed the intergrowth of the two uranium silicates—providing insight into their growth and crystallization behavior
