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.
 
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.

Bei der Masse der vorhandenen Literatur reichen die hier gemachten Angaben im Allgemeinen aus, um sich einen Überblick zu verschaffen. Unter den einzelnen Gruben lassen sich weitere Angaben finden und hoffe dem interessierten Leser und Sammler genügend Stoff an die Hand gegeben zu haben. In diesem Zusammenhang möchte ich mich bei den vielen Informanten bedanken, die mir schriftliches Material zukommen ließen und ihr Wissen näher gebracht haben und die mir zum Teil erstklassiges Stufenmaterial veräußerten um das Wölsendorfer Revier von einer Seite zu beschreiben, die es in dieser Form bisher nicht gegeben hat.

It is part of the so-called Painted Desert and shows with its various layers a strange and impressive scenery. Characterized by erosion, it is a treasure trove of fossils. The rock formations show a chronicle of the past and give clues about the events of bygone days. In the park you can exposure rock strata until 234 million years ago. The colorful desert hills, the flat mesas and shaped hills attributable primarily to Chinle Formation and are fluvial sediments, caused by water movement. Countless fossilized wood and tree trunks bear witness to a scrumptious earlier fauna.

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 seinem Inneren schwelt schon über 300 Jahren ein brennendes Kohleflöz. Je nach Wetterlage zeugt heute schweflig-modrig riechender Rauch, wenn auch längst nicht mehr so intensiv wie früher, von diesem unterirdischen Brandherd. An zwei bis drei Spalten tritt noch erkennbarer Wasserdampf aus. Die anzuteffenden pyritreichen, gefritteten Schiefertone, die eine rötliche Färbung aufweisen, gehören dem Westfal an.

Es handelt sich hierbei um das Landgruberflöz, später dann in Flöz Nr. 13, oder auch "Blücher" bzw. "Aster", umbenannt. Flöz Nr. 13 wird den Sulzbacher Schichten zugeordnet. Diese reichen von Leittonstein 5 bis zu Flöz Stolberg und erreichen Mächtigkeiten bis über 700 m und sind die kohlenreichste Schicht des Saarkarbon. Die Kohlenlager dieses Schichtkomplexes liegen bei über 100; davon sind 23 Flöze bauwürdig.

Für die Ursache des Brandes existieren verschiedene Theorien ... Ein Beitrag von Berthold Stein und Norbert Kirchhoff
