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.

Min­er­al por­trait olivine (ger­man)Olivine is not a separate mineral, but a member belonging to the forsterite-fayalite mixing series. Olivine belongs to the olivin-groupe whose end-members are calcio-olivine and tephroite. Forsterite is a magnesium silicate; fayalite an iron silicate. If commonly is spoken of olivine, it is usually a more or less iron-rich forsterite. The color of olivine is generally yellowish green, olive green to black. You will find much more interesting details in our portrait about this common mineral series.

Written and investigated by Peter Seroka. (Article in german)

Das Na­tur­wis­sen­schaftliche Mu­se­um Schön­born­er Hof Aschaf­fen­burgIm alten Bau des Schönborner Hofes befindet sich das Naturwissenschaftliche Museum der Stadt Aschaffenburg. Das bereits 1970 eingerichtete Museum zeigt neben einer rund 300 Exemplaren umfassenden ornithologischen Sammlung auch eine sehr sehenswerte und umfangreiche entomologische Sammlung (Insektensammlung). Die im Museum gezeigte Wanzensammlung gilt als eine der größten in Europa. Daneben befindet sich im Museum eine Mineraliensammlung, die einen Eindruck in den früheren Kupferabbau im Spessart gibt.

Hu­ber­s­tock (Hubr; Hu­ber open pit; Hub­ský peň)Bei der Fundstelle Huberstock (auch Tagebau Hubr, Steinbruch Hubr) handelt es sich um die Pinge eines im 16. Jh eingestürzten Bergbaus auf Zinn mit den umliegenden Halden (Beran 2006). Diese stammen sowohl aus dem geschichtlichen Bergbau, wie auch aus den Aktivitäten -untertage und übertage- in jüngster Zeit (20. Jh., Einstellung des Betriebs der Stannum 1991, Bergbau auf Wolfram und Zinn).

Auf der Fundstellenseite wird auf einen Beitrag des Förderbvereins der Lithothek verlinkt. Diese haben die Fundstelle in der Lithothek aufgearbeitet.

The Franken­holz Mine – A Hid­den Chapter of In­dus­trial His­to­ryFrom early tunnel construction in the 18th century to its final closure in the 1950s, the Frankenholz Mine in Germany’s Saar region was a key site of coal mining history. With ambitious shaft projects, its own cableway connection to Bexbach, and remarkable geological features – including fossil discoveries and natural oil seepages – the mine reflects both the rise of industrial progress and the dangers of underground work. Gas explosions, water ingress, and tragic accidents shaped the lives of thousands of miners. Frankenholz remains a compelling reminder of a bygone mining era.

Agate fan­tasiesNature forms over time, e.g. believed due to weathering, mineralization or crystallization, landscapes and rocks in which the human imagination identifies often strange formations out of the real world. An example of this are agates that, generally outwardly unattractive pose, in their interiors often true works of art.

Min­er­al Por­trait Gale­naIt is not possible to write a chapter about the mineral galena without looking at the history of lead and silver to name two of the most important raw materials and materials of humanity. How long people processed galena as main ore for the production of lead is unknown. As lead inter alia used as an additive to various melts (e.g. to bronze and the salt-cementation process for gold extraction) one can assume that the properties of this mineral were known before 3000 BC. Other sources speak of a history of lead about 7000-9000 years BC back.
