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.

Kün­stliche Kris­talle - Ko­rundorundsynthesen finden sich im Handel als Schmelzbirnen, in der Regel der Länge nach gespalten sind, um die inneren Spannungen im Kristall zu lösen. Sie besitzen einen kreisrunden Querschnitt. Ab und an erkennt man im Querschnitt auch eine trigonale Symmetrie. Wird das Material durch Tempern von den Spannungen befreit, sind die Korundbirnen komplett und im Querschnitt rund oder eher abgerundet dreiseitig. Synthetische Spinellbirnen sind in der Regel komplett und besitzen einen annähernd quadratischen, aber abgerundeten Querschnitt. In der Nähe des Keimes finden selten abgerundete Oktaederflächen.

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)

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

Sock­el zur Min­er­alien­präsen­ta­tion aus Plexi­glasZur Präsentation besonders schöner Mineralienstufen werden gerne Stufen auf transparente Sockel aus Kunststoff in die Vitrine gestellt. Die Sockel, die sich üblicherweise auf dem Markt befinden (Mineralienbörsen oder div. Zubehörgeschäfte im Internet), sind praktisch immer aus Plexiglas hergestellt. Die Preise variieren von Anbieter zu Anbieter.

In der folgenden Anleitung soll gezeigt werden, dass man aus geschnittenen Rohlingen mit einfachen Mitteln solche Sockel selbst hergestellt werden können.
