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 10531 members. Every month hundreds of thousands of visitors use our website as an information source.

In­clu­sionsInclusions are inside the crystal enclosed foreign materials like liquids, gases, hydrocarbons (oil, asphalt), sediment, NaCl, as well as other minerals or crystals. Inclusions can be a sort of fingerprint of the place of dicovery. Thus inclusions show us under which geologic conditions minerals had formed. This allows conclusions on the place of discovery.

The article deals with the different kinds of inclusions, her conditions of build, which minerals do often have inclusions and how they appear.

Fal­tenEine durch Faltung entstandene Verbiegung oder Verkrümmung einer ehemals horizontal geschichteten Gesteinseinheit in allen Größenordnungen. Je nach Form unterscheidet man Knickfalten, Biegefalten oder Fließfalten. Die Faltenformen Sattel (Antiform) und Mulde (Synform) sind abhängig von der Mächtigkeit des verfalteten Schichtpaketes, den mechanischen Eigenschaften der Gesteine, dem Vorhandensein von Abscherflächen und auftretenden Spannungen.

Sil­ver - min­er­al­o­gy, min­ing and his­to­rySilver and silver minerals are amongst the most desirabe objects since the beginning of mineral collecting. Silver wires and curls from Kongsberg and Freiberg are the coronation of each mineral collection. Beautiful pyrargyrites and proustites enhance each collector's heatbeat.

However, silver is not only the essence of high-end collecting but has contributed essentially to the history of mankind. Uncountable remain the millions of greek and phenician slaves, middle age european miners and millions of indios who have left their lives for silver.

Silver is one of the seven metals known since thousands of years, already been mentioned in the bible. Mountains of slag in Asia Minor, Arabia and on the agaen islands prove technologies to produce silver from lead ore; knowledges people had been acquainted with since at least 4.000 year B.C. Since the antiquity silver had been used to make finery and ornaments, however, most of this metal was used to stamp coins. The monetary system of many countries was based on silver; the one, who owned silver, was able to finance wars. One of the main pillars of power of Athens, Rome, the Phenicians, the church, the kings and queens of Castilia, the Austrian house of Habsburg and, last not least, of the Americans had been their control over the richest silver mines and the wars, which they made by paying their soldiery with silver coins.

ZincIin 1546 Georgius Agricola reported about a white metal which is fused to the Rammelsberg lead and silver melter and that you could scrape off. He called this metal "contrefey", because it could imitate gold. Agricola did not recognize that this metal was zinc. He further observed that a similar metal, which he named from some unknown reasons "ZINCUM" arose under similar circumstances in Silesia during smelting.
