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.

Cop­per 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 ... moreCopper 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

Für die hier vorgestellte Untersuchung wurden Spektren von Uranophan, Sklodowskit und Uranocircit aus der Literatur herangezogen. Bei den untersuchten Mineralien wurde nämlich festgestellt, dass auf dem gleichen Stück auftretende, andere Uranyl-Mineralien, die Messung verfälschen können, wenn deren Lumineszenz nicht räumlich sicher abgeblockt werden kann. Beispielsweise beeinflusste in einer ersten Messung die vergleichsweise starke Lumineszenz von Uranocircit die Messung an einer Uranophan-Probe aus Menzenschwand. Aus diesem Grund ist es sinnvoll, die Spektren weiterer potentiell auftretender Mineralien wie Uranocircit mit in die Untersuchung aufzunehmen, um bei der Bestimmung der Mineralien solche Einflüsse aufspüren zu können...

Von den weltweit wenigen Fundorten (darunter Brasilien, Sri Lanka und Zimbabwe) sind die russischen Alexandrite die hochwertigsten, da sie im Gegensatz zu den meist weniger kräftig gefärbten Steinen aus den anderen Ländern ihre Farbe von einem intensiven smaragdgrün zu einem tiefen purpurrot wechseln. Die Originalfundstelle im Ural war nach mehreren Jahrzehnten Abbau erschöpft und nur wenige dieser berühmten Alexandrite tauchen ab und zu auf dem Markt auf. Neuere Funde stammen aus Zimbabwe, Sri Lanka, Tansania, Tasmanien, Indien und Myanmar (Burma), besitzen jedoch nicht den starken Farbwechsel der russischen Alexandrite. Im Jahr 1987 entdeckte man in Hematita (Minas Gerais) in Brasilien Alexandrite, welche nahe an die Qualität der historischen russischen Steine herankommen und einen attraktiven ...

Emeralds, aquamarines, heliodors and morganites were and are used for the manufacture of jewelry because of their beauty. The common beryl is the main source of the metal beryllium; 80 % of beryllium ore is mined in the United States. The largest known crystal reached a length of 18 m.

This lavishly researched and very comprehensive portrait by the author Peter Seroka relates to history, name origin, causes of color, occurrences , paragenesis and the use of this mineral and its varieties. Subchapters with numerous photographs and drawings deal with the extraordinary beauty of the mineral. Each chapter itself is a separate portrait of a distinctive variety and its characteristics, occurrences, use and history.

Nevertheless, in the past, evil itself is said to have preached to the damned here from a large, solitary, towering rock spur. Today, the term Devil's Pulpit inspires one to play with associations, as do the drawings of agates found here. Their fantastic outlines, coupled with the unusual shape of the secondary rock, evoke images in the viewer that he would not have suspected in a stone. And on the devil's pulpit no longer an evil demon is waiting for the agate collector, but other executive powers threatening with purgatory... a contribution by Klaus Schäfer and others (in german)
