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.
 
Geolitho Foundation non-profit GmbH
Geolitho Foundation non-profit GmbH is the non-profit supporter of the Mineral Atlas (Mineralienatlas), the Lithotheque, the Geolitho Collection Management and the Marketplace and Store by collectors for collectors. The Foundation promotes public education in the field of mineralogy, geology, paleontology and mining by operating, maintaining and further expanding earth science projects.

Kas­par Maria Graf von Stern­bergKaspar Sternberg wurde als jüngster von 3 Söhnen des Grafen Johann von Sternberg geboren. Mit elf Jahren wurde er für die geistliche Laufbahn bestimmt und begann 1778 mit der priesterlichen Ausbildung im Collegium Germanicum in Rom. Er ging 1783 nach Regensburg, um eine kirchliche Laufbahn zu beschreiten. 1802 wurde er als Stellvertreter des Fürsten Thurn und Taxis die Spitze der dortigen politischen Verwaltung, des Landesdirektoriums.

"Ober­fränkisch­es Re­vi­er" a min­ing por­traitThe mining in the Franconian Forest has produced a lot of pits in the area and counts to the oldest mining areas in Germany. Indeed, one searches in the World Wide web in vain according to the information of which are documented by photos or maps. This comprehensive contribution gives you a wide view into this extended mininig area.

Nied­er­rhein... Am Ende der Braunkohlenzeit, im Pliozän, überwand der junge Rhein, aus der Mainzer Gegend kommend, zum ersten Mal das Rheinische Schiefergebirge. Mit dem Ausklingen der Braunkohlezeit schwand auch im nördlichen Rheinland das subtropische Klima. Zu dieser Zeit suchte der Rhein mit der Ur-Maas den Weg zum Meer und lagerte die ältesten Diluvialschotter in Form von wasserhellen und milchigen Quarzen sowie anderen Kieselgesteinen ab. ...

Pet­ri­fied For­est Na­tio­n­al ParkThe Petrified Forest is primarily a geological park, which owes its origin to the climate and geological events. It is part of the so-called Painted Desert and shows with its various layers a strange and impressive scenery. Characterized by erosion, it is a treasure trove of fossils. The rock formations show a chronicle of the past and give clues about the events of bygone days. In the park you can exposure rock strata until 234 million years ago. The colorful desert hills, the flat mesas and shaped hills attributable primarily to Chinle Formation and are fluvial sediments, caused by water movement. Countless fossilized wood and tree trunks bear witness to a scrumptious earlier fauna.

The Mu­nich Mi­cro­moun­ters and their Lithothek„What will be the fate of my collection once I will no longer be able to collect? There are specimens of unique beauty and extreme rarity in the collection, pieces that cannot be replaced since some localities are closed or have been obliterated. All this might be thrown away because not many people realise the value and importance hidden in these little unimpressive boxes”. Many micromounters are worried by these considerations and other factors. “My collection is an important part of my life and of my personality. If my collection dissapears, I too, will cease to exist without trace”. We, the Micromounters of the Münchener Mineralienfreunde, are no exception. Many times the future of our collections was subject of our discussions and conversations. Children and grand children are not always appreciative of their parents’ or grandparents’ passion.

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
