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 10533 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.

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

Min­er­al Por­trait Gale­naIt is not possible to write a chapter about the mineral galena without looking at the history of lead and silver to name two of the most important raw materials and materials of humanity. How long people processed galena as main ore for the production of lead is unknown. As lead inter alia used as an additive to various melts (e.g. to bronze and the salt-cementation process for gold extraction) one can assume that the properties of this mineral were known before 3000 BC. Other sources speak of a history of lead about 7000-9000 years BC back.

Min­er­al por­trait olivine (ger­man)Olivine is not a separate mineral, but a member belonging to the forsterite-fayalite mixing series. Olivine belongs to the olivin-groupe whose end-members are calcio-olivine and tephroite. Forsterite is a magnesium silicate; fayalite an iron silicate. If commonly is spoken of olivine, it is usually a more or less iron-rich forsterite. The color of olivine is generally yellowish green, olive green to black. You will find much more interesting details in our portrait about this common mineral series.

Written and investigated by Peter Seroka. (Article in german)

Min­er­al por­trait gar­netThis portrait mainly deals with the 6 classic garnets, their amazing history, the world’s best known classic and modern localities and deposits and their use as a gems or abrasives. It also deals with the common belief related to the non-existence of blue garnets and its refutation proven by new finds. A separate chapter deals with synthetic garnets. But it also deals with the mix up of definitions, groupings and old and unnecessary terms, which have finally been terminated or brought to a common denominator.

In 2012 the IMA (CNMNC) has defined garnets as members of the Garnet Supergroup, which include all minerals isostructural with garnet regardless of what elements occupy the four atomic sites; i.e. the supergroup includes several chemical classes . Those minerals are closely related to each other and may form a series with each other. Some garnets form intermediary minerals between each member, and may even be intergrown within a single crystal.

With the publication of the new nomenclature of the garnet supergroup, the term “garnet group” does not have its meaning anymore and the intermediate working term “Garnet superstructural group” has been replaced by “Garnet Supergroup”.
There are 32 approved species and 5 “candidate” species waiting on approval. The 32 species are subdivided by their Z-charge into 29 species, which belong to 5 groups and to 3 single representative species.
One of those 5 groups is the “Garnet group”, consisting of the 6 former (classic) garnets Pyrope, Grossular, Spessartine, Almandine, Uvarovite and Andradite plus 8 rarer garnets , as Menzerite-(Y), Eringaite, Goldmanite, Momoiite, Knorringite, Calderite, Majorite and Morimotoite.

Die Lithothek der Münch­en­er Mi­cro­moun­ter„Was soll nur aus meiner Micromount-Sammlung werden, wenn ich selbst einmal nicht mehr sammeln kann? Sie enthält doch Stücke von einmaliger Ästhetik, von längst erloschenen Fundstellen oder größter Seltenheit. Das alles droht unterzugehen, weil nach mir niemand den Wert erkennt, der in den zunächst unscheinbar wirkenden Döschen steckt.“ Dieser Gedanke wird bei vielen Sammlern von Micromounts diskutiert. Dabei wird die oben genannte Befürchtung immer wieder geäußert. Weniger häufig wird eine andere Frage offen angesprochen, die aber dennoch viele Sammler bewegt: „Soll meine Sammlerleistung, ein wichtiger Teil meines Lebens, gänzlich in Vergessenheit geraten?“
