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 10530 members. Every month hundreds of thousands of visitors use our website as an information source.

... As al­ready men­tioned else­where, min­ing in Il­me­nau dates back to the year 1200. In 1216, Count Pop­po v. Hen­ne­berg was en­fe­offed with the Ber­gre­gal by Frie­drich den II.

As already mentioned elsewhere, mining in Ilmenau dates back to the year 1200. In 1216, Count Poppo v. Henneberg was enfeoffed with the Bergregal by Friedrich den II. At that time one had discovered mineralised steep copper slate near Roda and on the Sturmheide. Presumably, individual miners had been enfeoffed, who extracted copper slate and sandstone in accordance with the mining freedom. This is generally regarded as the beginning of the first main period of Ilmenau mining. The ore was mined in small open pits to a maximum depth of 50m. ... A Contribution of {:10697:}

From ear­ly tun­nel con­struc­tion in the 18th cen­tu­ry to its fi­nal clo­sure in the 1950s, the Franken­holz Mine in Ger­many’s Saar re­gion was a key site of coal min­ing his­to­ry.

With ambitious shaft projects, its own cableway connection to Bexbach, and remarkable geological features – including fossil discoveries and natural oil seepages – the mine reflects both the rise of industrial progress and the dangers of underground work. Gas explosions, water ingress, and tragic accidents shaped the lives of thousands of miners. Frankenholz remains a compelling reminder of a bygone mining era.

Durch die großen Wintersportereignisse - Eisschnelllauf in Inzell, Biathlon in Ruhpolding -, aber auch durch das Skigebiet Winkelmoosalm - von Ruhpolding kommend auf dem Weg zum Parkplatz Seegatterl fährt man am Rauschberg vorbei - haben die östlichen Chiemgauer Alpen einen überregionalen Bekanntheitsgrad gewonnen.

Dabei hat diese Ecke der Alpen auch eine ganz andere Tradition. Über Jahrhunderte - grob von der Mitte des 16. Jh. bis in die Anfänge des 20. Jh. - wurde hier Bergbau betrieben, und das Metall auch weiterverarbeitet. Die großen Wälder dienten der Holzproduktion für diesen Bergbau und für die Salinen in Traunstein und Bad Reichenhall ... ein Beirag von Martin Stark

Weather­ing is a conti­nous pro­cess by which rocks are bro­ken down and de­com­posed by the ac­tion of hu­mid­i­ty (rain), wind, tem­per­a­ture changes, chem­i­cal agents, bac­te­ria and plants. Be­ing an in­te­gral part of the rocks cy­cle, weather­ing is the ini­tial stage to­wards de­nu­da­tion, which re­sults in gen­er­al l ... moreWeathering is a continous process by which rocks are broken down and decomposed by the action of humidity (rain), wind, temperature changes, chemical agents, bacteria and plants. Being an integral part of the rocks cycle, weathering is the initial stage towards denudation, which results in general lowering of the land surface. An essential feature is that it affects rocks in situ; no transportation is involved. This is the factor which dsitinguishes weathering from erosion. The two main types of weathering are mechanical and chemical. Climate plays a leading role in weathering, whereas chemical weathering is almost absent in arid regions. Effecrtive freeze-thaw cycles are confined to cold temperate and permafrost climates.

Erosion is part of the process of denudation which involves the wearing away of land surface by mechanical action of transported debris. Main cycles of erosion are glaciers, wind erosion, marine erosion.

Das Min­er­al Wulfenit wurde - so die all­ge­mein ver­breit­ete Ver­sion bzw. der all­ge­mein ver­breit­ete Ir­r­tum - Ende des 18.

Jh. vom österreichischen Jesuiten (Abbé), Botaniker und Mineralogen Franz Freiherr von Wulfen entdeckt und von ihm in seiner berühmten "Abhandlung vom Kärnthnerischen Bleyspathe" im Jahr 1785 beschrieben und gezeichnet, obwohl es bereits 1772 eine Veröffentlichung des Siebenbürgener Mineralogen und Geologen Ignaz von Born gab, mit dem Titel: "Plumbum spatosum flavo-rubrum pellucidum" (von Annaberg in Niederösterreich). Von Wulfen selbst zitierte den berühmten Bergrat Scopoli, welcher in seiner "Einleitung zur Kenntnis der Fossilien" den kärntherischen Bleyspat als " ungestaltete, ockergelblichte, versteinerte Bleyerde, welche im Zentner 27 bis 30 Pfund Blei enthält " beschrieb... ein Beitrag von Peter Seroka

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
