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 10531 members. Every month hundreds of thousands of visitors use our website as an information source.

Es ist eng verwandt mit dem stets faserig aufgebauten Chalcedon. Die Verwandtschaft ist so eng, dass sogar Stücke vorkommen, bei denen körnig und faserig aufgebaute Quarzmaterialien miteinander verwachsen sind. Jaspis ist nur sehr selten in reiner Form zu finden. Durch Verwachsungen mit Achat und Opal, aber auch durch Fremdbeimengungen von bis zu 20 % wie Tonerde, Eisenoxid, Eisenhydroxid und Manganhydroxid schwanken seine chemischen und physikalischen Eigenschaften sehr stark. Da die Menge und Verteilung dieser Beimengungen über das Erscheinungsbild entscheiden, ist der Farb- und Varietätenspielraum des Jaspis außerordentlich groß.... Ein Beitrag von Peter Seroka

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.

Erst knapp 50 Jahre später liegen wieder Nachrichten vor, und zwar Abrechnungen aus den Jahren 1782 bis 1791. Die damaligen Pächter waren die Krettnicher Einwohner Nicolaus Wiesen, Matthias Finkler und Johann Bathis, Ersterer hatte in den 10 Jahren 346 Rtl., der zweite 95 Rtl. und der letzte 146 Rtl. eingenommen. Hauptabnehmer waren Johannes Scherer in Scheuern, Pastor Anhäuser in Lockweiler, sowie Johannes Bördeler (Birtel) in Krettnich, die offenbar das abgenommene Erz auf eigene Rechnung weitervertrieben.

„What will be the fate of my col­lec­tion once I will no longer be able to col­lect?

There are specimens of unique beauty and extreme rarity in the collection, pieces that cannot be replaced since some localities are closed or have been obliterated. All this might be thrown away because not many people realise the value and importance hidden in these little unimpressive boxes”. Many micromounters are worried by these considerations and other factors. “My collection is an important part of my life and of my personality. If my collection dissapears, I too, will cease to exist without trace”. We, the Micromounters of the Münchener Mineralienfreunde, are no exception. Many times the future of our collections was subject of our discussions and conversations. Children and grand children are not always appreciative of their parents’ or grandparents’ passion.

Cop­per was one of the first me­t­als ev­er ex­tract­ed and used by hu­mans, and it has made vi­tal con­tri­bu­tions to sus­tain­ing and im­prov­ing so­ci­e­ty since the dawn of civ­i­l­iza­tion.

The metal and its alloys have been used for thousands of years. Copper was first used in coins and ornaments starting about 8000 B.C., and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as сyprium (metal of Cyprus), later shortened to сuprum.

The discovery that copper alloyed with tin produces bronze marked the beginning of the Bronze Age at about 3000 B.C.
Copper is easily stretched, molded, and shaped; is resistant to corrosion; and conducts heat and electricity efficiently. As a result, copper was important to early humans and continues to be a material of choice for a variety of domestic, industrial, and high-technology applications today.

Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite and malachite and have been widely used historically as pigments. ... a contribution by Peter Seroka
