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.

Der gewöhnliche Habitus des Anatas ist dipyramidal, wobei die Doppelpyramide {111} spitzer als die Doppelpyramide {112} ist und der Form nach einem Oktaeder gleichkommt (aber auch rundlich oder flachdipyramidal). Die Enden der Kristalle sind unterschiedlich, oft nur an den Kristallen eine Dipyramide ohne weitere Flächen. Dies ist der am häufigst vorkommende Habitus. Weniger, jedoch nicht selten, treten Dipyramiden mit abgestumpften Spitzen auf, bzw. auch durch eine Basisfläche angeschnitten, welche wiederum von Flächen weiterer Dipyramiden begleitet sein kann. Stumpfere Dipyramidern können ... Ein Beitrag von Peter Seroka

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 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

Ac­tu­al­ly, this is a pic­turesque place in a well-kept for­est.

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)

"Aus den Eisengruben kommt das für den Waffenträger exzellenteste und das perverseste Geschenk. Wir pflügen mit diesem Geschenk die Erde, wir pflanzen die Sträucher, wir bearbeiten die Böden der Felder, wir bauen mit dieser Waffe Häuser, zerklopfen Steine und verwenden das Eisen auf vielfache Weise. Doch mit dem gleichen Geschenk streiten wir, führen wir Kriege und plündern; wir verwenden es nicht nur aus der Nähe, sondern lassen es über weite Strecken fliegen, aus Schießscharten, mit kräftigen Händen, als gefiederte Pfeile. Nach meiner Meinung ist das Eisen das sittenloseste Ding, welches dem menschlichen Geist entsprang. Und damit der Tod noch schneller eintritt, gaben wir ihm eiserne Flügel. Aus all diesen Gründen trägt der Mensch die Schuld und nicht die Natur." - Ein Mineralienportrait geschrieben von Peter Seroka

Among the most spectacular finds are the fantastic light blue calcites from the Julia mine in Bilbao, which enraptured collectors' hearts to about the mid-1970s. At about the same time the zinc mine Las Manforas at Aliva supplied excellent, highl lustrous Calcites, often associated with the world's best red Sphalerites. ...

Amonsgt the forms of calcite the pinacoid is unique as it consists of exactly two parallel and oriented perpendicular to the c-axis surfaces. All other Calcite forms have either six or twelve areas. The pinacoid is an open form, with which it can not really include space; so the pinacoid must accompany other forms on the calcite crystal ...
