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.

Basalt­säulen... Basaltsäulen sind erkaltete und erstarrte basaltische Lava. Die Erscheinungsform dieser erkalteten basaltischen Lava ist hauptsächlich von zwei Faktoren abhängig. Eruptierte Lava kühlt recht schnell aus zu einem zusammenhängenden Gesteinsgefüge, das je nach Temperatur und Gasgehalt als Pahoehoe-Lava oder als Aa-Lava erstarrt. Findet die Abkühlung jedoch verzögert statt, entstehen durch Kontraktion (Schrumpfung) nicht selten meterlange polygonale Basaltsäulen ... Ein Beitrag von Peter Seroka

The "Eisen­ham­mer" (iron ham­mer) to He­im­buchen­thal The former "Eisenhammer" (iron hammer) to Heimbuchenthal has to show a very interesting history. The hammer mill established at the beginning of the 18th century reached at the end of the 18th century in the possession of the family Rexroth under whose guidance the company came to the full blossom. The squires showed a high social engagement which was reflected in the reimbursement of the workers, but also in the enlargement of the entrance ways. In specially constructed schools up to 30 children were teaches on the hammer mill property. On one, from oaks surrounded cemetery the late squires and their members were buried. In 1891 the company was discontinued and the hammer mill was converted into a court estate. From the industrial monument all buildings except the great smithy are even today in a very good state.

In­di­ca­tor stoneA Scandinavian indicator stone is a glacial erratic composed of a characteristic rock type derived from a small known source area in Scandinavia. This term not only applies to igneous and metamorphic rocks but also to some sedimentary rocks. The Jotnian Sandstone and most of the Palaeozoic limestones, and the Old Red Sandstone are not included in the definition, although the presence of these and other rocks provide some evidence about the source area(s) of erratics and should certainly not be neglected in a stone count. In all cases we recommend including the whole assemblage of erratics/stones in such account. This makes it possible to use several methods of Interpretation. However, it should be pointed out that the practise used in the past, whereby each researcher had her/his own method of interpreting stone counts, has proved to be unsatisfactory. We demonstrate on the bases of over 2000 counts of indicator stones that we have carried out on assemblages mostly from Lower Saxony and Schleswig-Holstein, but also from other N.German states and neighbouring countries, that the TGZ method (LÜTTIG 1958) yields the most reliable results. In addition to this method, the sources of individual indicator stones may be plotted on a so-called circle map and can be integrated with possible source data and the relative frequencies of other erratics in the assemblage. Some rock types are more suitable as indicator stones then others. It is unwise to use clearly unsuitable rock types; this would considerably reduce the reliability of the method and lead to erroneous results.

Min­er­alien­por­trait Sil­berSilber und Silbermineralien gehören zu den gesuchtesten Objekten des Bergbaus , seitdem Menschen Mineralien sammeln. Silberlocken aus Kongsberg und Freiberg sind die Krönung einer jeden Mineraliensammlung. Schöne Pyrargyrite und Proustite lassen jedes Sammlerherz höher schlagen. Aber Silber als Mineral ist nicht nur Inbegriff höchstwertigen Sammelns, sondern hat auch wesentlich zur Geschichte der Menschheit beigetragen. Nicht zu zählen sind die Millionen von athener und phönizischen Sklaven, mittelaterlichen europäischen Knappen und Millionen Indios, die wegen des silbernen Metalls ihr Leben im Berg gelassen haben.

Silber ist eines der sieben Metalle, welche man seit Jahrtausenden kennt. Es wird bereits in der Bibel erwähnt ; Berge von Schlacken in Vorderasien und auf den ägäischen Inseln sind Beweise für die Technologie der Silbergewinnung aus bleihaltigem Erz, welche mindestens viertausend Jahre v.Chr. bekannt war.
Silber wurde seit der Antike als Metall für Schmuck und Ornamente, weitaus mehr jedoch zur Prägung von Münzen verwendet. Das Währungssystem vieler Länder beruhte auf Silber; wer Silber besaß, konnte auch Kriege führen. Die Macht Athens, Roms, der Phönizier, der Kirche, der Könige von Kastilien, der Habsburger und letztlich der Amerikaner beruhte nicht unwesentlich auf deren Besitz der größten Silbergruben und der Kriege, welche mittels mit Silbermünzen bezahlter Söldner geführt wurden.

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.
