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.

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.

There are specimens of unique beauty and extreme rarity in the collection, pieces that cannot be replaced since some localities are closed or have been obliterated. All this might be thrown away because not many people realise the value and importance hidden in these little unimpressive boxes”. Many micromounters are worried by these considerations and other factors. “My collection is an important part of my life and of my personality. If my collection dissapears, I too, will cease to exist without trace”. We, the Micromounters of the Münchener Mineralienfreunde, are no exception. Many times the future of our collections was subject of our discussions and conversations. Children and grand children are not always appreciative of their parents’ or grandparents’ passion.

Schon im Altertum war der Zirkon als Edelstein bekannt und wurde an einigen der weltweit ältesten archäologischen Ausgrabungsstätten gefunden. Er taucht in verschiedenen alten Schriften auf, darunter in der Bibel und einem Hindu-Gedicht über den mythischen Kalpa-Baum (Kamana Kalpa Vraksha), der mit Blättern aus Zirkon geschmückt gewesen sein soll. Einige Quellen erwähnen eine jüdische Legende, in der ein Engel namens „Zirkon“ vorkommt, der ... Ein Beitrag von Peter Seroka

Mai 1683 wurde laut dem Mutungsregister des Fürstentums Waldeck eine Mutung in der alten „Silberkuhle“ auf Blei, Gold, Silber und was sonst der Herr so beschert, verliehen. Die Grube wurde von Bergleuten aus Clausthal im Harz betrieben. Es wurde über und auch Untertage, wahrscheinlich silberhaltiger Bleiglanz abgebaut. 1747 gab es nochmals einen Hinweis auf den dortigen Bergbau. Die Brüder Götte aus Giershagen schürften dann um 1890 in der Gegend nach Erzen und wurden in der Silberkuhle fündig. Sie fanden in dem Schreinermeister Jung aus dem Hannöverschen einen Geldgeber der 30.000 Mark in den Bergbau steckte. Im Jahre 1893 erfolgte die Verleihung und ein Jahr später 1894 die Vereinigung der Bergwerksfelder „Mathias 1 bis 12“ zu einem Bergwerksfeld. - Ein Bericht von Ingo Löffler

REE belong to the most important raw materials of the 21st century, which are used in a large number of key technologies. However, due to the fact that almost 97% of the world's REE are mined and produced in China, REE have become an ongoing political issue, mainly amongst technology providing countries like the US, Japan and Western Europe.

This portrait tries to explain the characteristics of REE and their role for our modern world. Written and investigated by Peter Seroka. (Article in german)

Der Grand Canyon ist einer der best erforschten Aufschlüsse, dennoch sind die Entstehung und die dafür benötigten Zeiträume nicht vollends geklärt. In der Zweitspann von 65 bis 20 Millionen Jahren (Ma) wurde das Kaibab Plateau an dessem südwestlichem Rand der Grand Canyon liegt auf bis zu 3000m über den Meeresspeigel angehoben. Nach einer Phase der Erosion in der nahezu vollständig die im Mesozoikum abgelagerten Sedimente weg erodierten begann der Ur-Colorade sich durch die verbliebenen Schichten zu graben. Nach heutigem Stand benötigte der Colorado wenige Millionen Jahre um den heutigen Grand Canyon freizulegen. Die Erosion in die Tiefe erfolgte dabei in den letzten 2 Ma.
