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 10558 members. Every month hundreds of thousands of visitors use our website as an information source.

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“garnet group” does not have its meaning anymore and the intermediate working term “Garnet superstructural group” has been replaced by “Garnet Supergroup”.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.

Das waren: Grube Max, Grube Hanns und die Aufschlußgrube Lissenthan. Bedeutet das nicht alle Stufen die den Namen Johannesschacht tragen auch aus dieser Grube stammen. Angebote sollten kritisch hinterfragt werden.
Stufen die auf Halde gefunden wurden oder im über Tage Bereich bekommen als Fundortbezeichnung "Halde der Grube Johannesschacht" oder "über Tage Fund Grube Johannesschacht", u.U. noch mit einem entsprechenden Hinweis.
1929 wird erwähnt, daß bis zu einer Teufe von 28 Meter grobspätiger Stinkspat vorgefunden wurde. Uranmineralien wurden erst ab einer Teufe von 18 m angetroffen.
1931 wurde Stinkspat in Würfeln, Oktaedern, Rhombendodekaedern sowie... Ein Beitrag von Michael Kommer

Geologen sprechen von einer Schichtquelle. Von hier oben genießt man den Blick über das Dorf und die Kirkeler Burg. Auf unserem weiteren Weg erreichen wir bald den Frauenbrunnen, eine weit und breit bekannte Quelle. Etwa 50 m oberhalb beginnt in östlicher Richtung der geologische Lehrpfad, entstanden 1983. Am Anfang des Weges wurde eine Übersichtskarte aufgestellt, die das Saarland, sowie angrenzende Teile geologisch umfaßt und die Fundorte der aufgestellten Steine anzeigt...
