Vilo­co Mine, La Paz, Bo­livienDie Viloco Mine liegt hoch über der Ortschaft Viloco auf bis zu über 4900m. Die Mine zieht sich dabei über mehrere hundert Meter entlang des Berges in die Höhe. Sie befindet sich im "Cordillera Quimsa Cruz" (Aymara-Sprache) oder "Kimsa Krus" (Quechua-Sprache) oder auch "Tres Cruces" (deutsch "drei Kreuze") genanntem Gebirgszug im Departamento La Paz. Zahlreiche Stolleneingänge und meist verfallene Bergwerksbauten zeugen von einer umfangreichen Bergbautätigkeit. Verschiedene Quellen schreiben auch von Araca Mine, der Name sei quasi austauschbar. Hierbei handelt es sich um einen historischen Namen.

Kies­grube Oh­le & Lau in Groß Pam­pau... Forschungsbohrungen (1988, Groß Pampau I & II) ergaben, dass ab ca. 7 m Tiefe der Tonschichten das mittlere Langenfeldium, ab ca. 19 m das untere Langenfeldium und ab ca. 29 m das obere Reinbekium beginnnt. Während des Hauptabbaus (Seeseite) in Groß Pampau waren ca. 17 m der Glimmertonschichten mehr oder weniger zugänglich, als Ton für die Deponieabdeckung abgebaut wurde. Anhand der aufgelesenen Fossilien (mehr als 150 Arten konnten gefunden werden) und dem Vergleich dieser Arten mit heute noch in gemäßigteren Regionen lebenden Vertretern (und deren Lebensbedingungen), geht man von einer damals durchschnittlichen Wassertiefe von 50 - 80 m aus. ...

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)

Ge­o­log­ic Por­trait - Weather­ing and Ero­sionWeathering is a continous process by which rocks are broken down and decomposed by the action of humidity (rain), wind, temperature changes, chemical agents, bacteria and plants. Being an integral part of the rocks cycle, weathering is the initial stage towards denudation, which results in general lowering of the land surface. An essential feature is that it affects rocks in situ; no transportation is involved. This is the factor which dsitinguishes weathering from erosion. The two main types of weathering are mechanical and chemical. Climate plays a leading role in weathering, whereas chemical weathering is almost absent in arid regions. Effecrtive freeze-thaw cycles are confined to cold temperate and permafrost climates.

Erosion is part of the process of denudation which involves the wearing away of land surface by mechanical action of transported debris. Main cycles of erosion are glaciers, wind erosion, marine erosion.

The Mu­nich Show 2024The mineral fair ended successfully and the author of this article received only positive feedback. 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...
