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.

Ac­tu­al­ly, this is a pic­turesque place in a well-kept for­est.

Nevertheless, in the past, evil itself is said to have preached to the damned here from a large, solitary, towering rock spur. Today, the term Devil's Pulpit inspires one to play with associations, as do the drawings of agates found here. Their fantastic outlines, coupled with the unusual shape of the secondary rock, evoke images in the viewer that he would not have suspected in a stone. And on the devil's pulpit no longer an evil demon is waiting for the agate collector, but other executive powers threatening with purgatory... a contribution by Klaus Schäfer and others (in german)

Bei der γ-Spek­trome­trie han­delt es sich um ein rel­a­tiv kom­plex­es Messver­fahren, welch­es als Ergeb­nis die gemesse­nen Ereig­nisse als Funk­tion der γ-En­ergie aus­gibt.

Dadurch ist es möglich, die im Messgut enthaltenen Nuklide mit γ-Übergängen qualitativ und quantitativ zu bestimmen. Für die Mineralogie ist es eigentlich die einzige, zerstörungsfreie Möglichkeit, die Aktivität und Nuklidzusammensetzung einer Stufe mit hoher Genauigkeit zu bestimmen (rechnerische Ermittlung der Efficiency vorausgesetzt).

Die hierzu benötigten Detektoren müssen also in der Lage sein, Ereignisse nach ihrer durch Wechselwirkung mit γ-Strahlung deponierten Energie aufzulösen. Da die Wechselwirkungswahrscheinlichkeit von γ-Quanten mit zunehmender Dichte und Kernladungzahl Z der Materie ansteigt, ist man bestrebt, für die γ-Spektrometrie entsprechende Detektoren einzusetzen. Diese sind hauptsächlich anorganische Szintillationsdetektoren (z.B. NaI(Tl)) oder Halbleiterdetektoren (z.B. HPGe)... ein Beizrag von Markus Noller

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.

Der Deutsch-Amerikaner Emil Winter erwirbt die Schürfrechte und gründet die Austro-American Magnesite Group, die in Radenthein mit der Errichtung eines beachtlichen Magnesitwerkes begann.
1925 wurden die Magnesit-Lagerstätten am Weißenstein und der Rettenwand bei Hochfilzen in Tirol entdeckt.
1928 sicherte sich die Austro-American Magnesite Group die Abbaurechte dafür und fusionierte mit der Allgemeinen Automobil G.m.b.H. in Wien zur Austro-American Magnesite Company. Im gleichen Jahr wurde mit dem Abbau im Untertagebetrieb begonnen.
bis circa 1930 konnte man von einem österreichischen Magnesit Monopol sprechen... Ein Beitrag von Michael Kommer
