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.

Grube Häusler & Co. - Ne­bel­berg... Eigentümlich ist hier insbesondere, daß die ausgebildeten Flußspatkristalle ( es wurde bis jetzt fast nur das Hexaeder gefunden ), immer stark verunreinigt sind, während das kristalline Gangmaterial weit höhere Reinheit besitzt. Die Verunreinigung geht soweit, daß z.B. Kupferkies, Pyrit, Quarz oder Ton im Innern der in Intervallen aufgebauten Kristalle gefärbte Schichten bildet. Es scheinen hier erst die zuletzt in die Höhe gestiegenen Lösungen so intensiv mit Sulfiden verunreinigt gewesen zu sein. Außerdem sind die Kristalle meist treppenartig gelagert, was durch die stengelige Ausbildung der Unterlage bedingt ist... Ein Beitrag von Michael Kommer

Agate fan­tasiesNature forms over time, e.g. believed due to weathering, mineralization or crystallization, landscapes and rocks in which the human imagination identifies often strange formations out of the real world.

Mi­na Pre­cau­ción - La Unión min­ing area - spainFor Mineral collectors who travel in their vacation to the mining area of La Union, the mina Precaución is an easy to reach and in 2010 a worthwhile target to collect attractive pieces with hemimorphite, calcite and more minerals on contrast rich matrix. Equipped with helmet, forehead lamp, chisel and hammer nice pieces can be rescued easily, taking into account the security rules for mining visits.

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

Cop­per - one of the old­est me­t­als of mankindCopper was one of the first metals ever extracted and used by humans, and it has made vital contributions to sustaining and improving society since the dawn of civilization.
The metal and its alloys have been used for thousands of years. Copper was first used in coins and ornaments starting about 8000 B.C., and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as сyprium (metal of Cyprus), later shortened to сuprum.

The discovery that copper alloyed with tin produces bronze marked the beginning of the Bronze Age at about 3000 B.C.
Copper is easily stretched, molded, and shaped; is resistant to corrosion; and conducts heat and electricity efficiently. As a result, copper was important to early humans and continues to be a material of choice for a variety of domestic, industrial, and high-technology applications today.

Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite and malachite and have been widely used historically as pigments. ... a contribution by Peter Seroka
