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.

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.

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

... As al­ready men­tioned else­where, min­ing in Il­me­nau dates back to the year 1200. In 1216, Count Pop­po v. Hen­ne­berg was en­fe­offed with the Ber­gre­gal by Frie­drich den II.

As already mentioned elsewhere, mining in Ilmenau dates back to the year 1200. In 1216, Count Poppo v. Henneberg was enfeoffed with the Bergregal by Friedrich den II. At that time one had discovered mineralised steep copper slate near Roda and on the Sturmheide. Presumably, individual miners had been enfeoffed, who extracted copper slate and sandstone in accordance with the mining freedom. This is generally regarded as the beginning of the first main period of Ilmenau mining. The ore was mined in small open pits to a maximum depth of 50m. ... A Contribution of {:10697:}

Diese ist ungefähr 6 km lang und 1 km breit. Sie liegt dicht am südlichen Rand des Brockengranites.

Es wurden in diesem Revier etwa 18 erzführende Gänge und 6 bis 8 taube "Ruscheln" im Laufe der Betriebszeit erschlossen und mehr oder weniger intensiv abgebaut. Auserhalb dieses "Silberdreieckes" sind noch andere Erzgänge bekannt, die jedoch eine andere Mineralführung aufweisen: Eisenspat, Schwerspat und nur geringe Mengen von Pb-, Zn- und Cu-Sulfiden.

Die Streichrichtung der Erzgänge verläuft zwischen 130° und 150° (quer zu den Faltenachsen), die der Ruscheln von 70° bis 80° sowie von 100° bis 110°. Diese Ruscheln sind ... Ein Beitrag von:

Although visitor numbers appeared slightly lower than last year, the fair remained vibrant and diverse. Highlights included the collector displays and the special exhibition on natural resources, while the fossil section was somewhat smaller.
Some visitors expressed a wish for more seating areas, opportunities for exchange, and more eye-catching advertising, yet overall the event left a very positive impression and remains a must-visit for collectors and families alike.

At 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
