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.

Many dealers were extremely satisfied. According to the organizer, 18,000 guests visited the halls on Saturday alone. Both days were a hive of activity and the numerous children's attractions were well received. Parents were everywhere with their children to complete the geo-rally.

For mineral collectors, the usual dealers were on site, although some tables remained empty. There were no highlights from the scene or overflowing tables with identical material from new finds. However, one stand with an impressive selection of Germanite chunks was a welcome novelty.

The special exhibition “The Impossible Crystal” was a success. Even if not all the exhibits could be described as “impossible crystal”, all the pieces were of the best quality and well worth seeing. In the B halls, the author visited the “Young Designers”, including a student who presented cast silver jewelry in an organic design that showed off the embedded stones to their best advantage - an impressive piece of work...

Es gibt nir­gend­wo im Uni­ver­sum ei­nen per­fek­ten Kris­tall, denn jed­er Kris­tall hat eine Ober­fläche und für die Atome auf der Ober­fläche ist die Umge­bung an­ders als für Atome im Vol­u­men. Die Ober­fläche ist somit ein De­fekt. Reale Kris­talle sind damit al­so Kris­talle, die De­fekte en­thal­ten.

Die Oberfläche ist somit ein Defekt. Reale Kristalle sind damit also Kristalle, die Defekte enthalten.

Eine einfache Definition für Defekte in Kristallen ist die Betrachtung der Umgebung der Atome im Kristall. Falls die unmittelbare Umgebung - streng genommen im zeitlichen Mittel, da die Atome im Kristall wegen der Temperatur um ihre Position wackeln - um ein beliebig herausgegriffenes Atom anders ist als die Umgebung eines Referenzatom in einem perfekten Teil des Kristalls, ist ein Defekt Ursache für diese Änderung. Für ein Atom auf der Oberfläche eines Kristalls ist diese Bedingung zweifellos erfüllt, da die eine Hälfte des Raumes keine Atome des Kristalls hat. Es gibt also prinzipiell keine perfekten Kristalle.

From 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.
