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.

Sie enthält doch Stücke von einmaliger Ästhetik, von längst erloschenen Fundstellen oder größter Seltenheit. Das alles droht unterzugehen, weil nach mir niemand den Wert erkennt, der in den zunächst unscheinbar wirkenden Döschen steckt.“ Dieser Gedanke wird bei vielen Sammlern von Micromounts diskutiert. Dabei wird die oben genannte Befürchtung immer wieder geäußert. Weniger häufig wird eine andere Frage offen angesprochen, die aber dennoch viele Sammler bewegt: „Soll meine Sammlerleistung, ein wichtiger Teil meines Lebens, gänzlich in Vergessenheit geraten?“

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.

Min­er­al por­trait gar­netThis portrait mainly deals with the 6 classic garnets, their amazing history, the world’s best known classic and modern localities and deposits and their use as a gems or abrasives. It also deals with the common belief related to the non-existence of blue garnets and its refutation proven by new finds. A separate chapter deals with synthetic garnets. But it also deals with the mix up of definitions, groupings and old and unnecessary terms, which have finally been terminated or brought to a common denominator.

In 2012 the IMA (CNMNC) has defined garnets as members of the Garnet Supergroup, which include all minerals isostructural with garnet regardless of what elements occupy the four atomic sites; i.e. the supergroup includes several chemical classes . Those minerals are closely related to each other and may form a series with each other. Some garnets form intermediary minerals between each member, and may even be intergrown within a single crystal.

With the publication of the new nomenclature of the garnet supergroup, the term “garnet group” does not have its meaning anymore and the intermediate working term “Garnet superstructural group” has been replaced by “Garnet Supergroup”.
There are 32 approved species and 5 “candidate” species waiting on approval. The 32 species are subdivided by their Z-charge into 29 species, which belong to 5 groups and to 3 single representative species.
One of those 5 groups is the “Garnet group”, consisting of the 6 former (classic) garnets Pyrope, Grossular, Spessartine, Almandine, Uvarovite and Andradite plus 8 rarer garnets , as Menzerite-(Y), Eringaite, Goldmanite, Momoiite, Knorringite, Calderite, Majorite and Morimotoite.

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 GipsDer Gips und seine große Verwendbarkeit zu plastischen Anwendungen, zur Innenraumgestaltung und als (kalkhaltiger) Gipsmörtel waren schon seit dem Altertum bekannt. In den Keilschriften der Sumerer und Babylonier finden sich Hinweise für die Verwendung von Gips, ebenso in Jericho (6000 v. Chr.). Ab 3000 v. Chr. wurde in Uruk und später in Ägypten Gips auch als Mörtel verwendet, dem Kalk oder Steine als Verunreinigung oder zur Streckung beigemengt waren, u.a., um die Blöcke der Sphinx (2700–2600 v. Chr.) sowie der Großen Pyramide von Gizeh in Form kalkhaltiger Gipsmörtel zu verbinden, bzw. zu verfugen. Der Mörtel der großen Cheops-Pyramide besteht zu 83 Proz. aus Gips. Auch lichtdurchlässige Scheiben aus Alabaster waren bei den Ägyptern bekannt.

Die minoische Kultur verwendete Gipsmörtel und Alabaster anstatt von Marmor als Fußboden oder Wandbelag und als Baustein (Palast von Knossos, 2100–1800 v. Chr. und Palast von Phaistos) und der griechische Naturforscher Theophrastos von Eresos beschrieb in einer Abhandlung die Herstellung von Gips. In Griechenland wurde Gips wegen seiner leichten Bearbeitbarkeit auch für Bauornamente an den Häusern genutzt. Der griechische Geograph Herodot (490/480 - 424 v.Chr.) erzählt von den Äthiopiern, daß sie ihre getrockneten Leichname übergipsten und schön anmalten. Der römische Architekt Vitruv (1. Jh. v.Chr.) und Plinius d.Ä. (23 - 79 n.Chr.) sprechen von der Benutzung des Gipses zu Bauzwecken, und letzterer erzählt, daß der griechische Bildhauer Lysistratos (2. Hälfte des 4. Jh. v.

This year not only the name seems to change away from the "Munich Mineral Show" changing to "The Munich Show". The new exhibition management, led by the young Mr. Keilmann seems not quite knowing where to go or has something bigger in mind. One can imagine something in "Munich Mineral Days", it is difficult in the name "The Munich Show". The new show management seems to leave the common way, to keep all options open with a new name. - A comment and fair report written in german language by Stefan Schorn
