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.
 
Geolitho Foundation non-profit GmbH
Geolitho Foundation non-profit GmbH is the non-profit supporter of the Mineral Atlas (Mineralienatlas), the Lithotheque, the Geolitho Collection Management and the Marketplace and Store by collectors for collectors. The Foundation promotes public education in the field of mineralogy, geology, paleontology and mining by operating, maintaining and further expanding earth science projects.

Calcite is one of the most abun­dant na­t­u­ral min­er­als. It is found in very dif­fer­ent shapes, both com­pact as lime­s­tone as well as sin­ter in caves and in the crys­tal­line state.

It is found in very different shapes, both compact as limestone as well as sinter in caves and in the crystalline state. But even in our daily life calcite is always present: in some regions it blockes water pipes as "chalk", we build our houses with it, it is in our food chain and without it we could not stand upright.

Calcite is not rare, but the varied mineral on Earth. The variety of forms and variations of the forms of calcite are unmatched in the world of mineralogy. By 2009, more than 800 Calcit forms have been described.

Eine Umfahrung des Baufeldes der Grube Johannesschacht fand deshalb statt, weil sich die Grundstücke und somit auch das untertägige Grubenfeld der Grube Johannesschacht bereits im ...

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.

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

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.

In der direkten Umgebung der größeren Mandeln kann man mit viel Glück einen kleinen Graphiteinschluss ausma ein Beitarg von u.a. Klaus Schäfer chen, der von einigen Sammlern durch angenommene Bildung von Kohlenstoffgasen als mitverantwortlich für die Hohlraumbildung angesehen wird. Diese Graphiteinschlüsse wurden bei der Bildung des Schlotes, als dieser durch tiefer gelegen karbonische Schichten brach, mitgerissen. Die von aussen nach .... Ein Beitrag von Klaus Schäfer
