Land­kreis Waldeck-Franken­bergDie Goldvorkommen im Landkreis Waldeck-Frankenberg gehören zu den klassischen Vorkommen in Deutschland. Die Goldgewinnung in dieser Region reicht bis in die Zeit vor dem Dreißigjährigen Krieg zurück. Es wurde nicht nur Gold gewaschen, sondern auch bergmännisch so am Eisenberg bei Korbach abgebaut... ein Beitrag von Ingo Löffler

Das Berg­bau­re­vi­er Freiberg... zu Anfang des 18. Jahrhunderts war Freiberg am Boden. Die Einwohnerzahl ging zurück, das Montanwesen war größtenteils zerstört und das Silberausbringen hatte einen Tiefstand von 1.211 kg erreicht. Erst Mitte des 18. Jahrhundert ging es wieder aufwärts; da arbeiteten bereits wieder 4.700 Bergleute in Freiberg und seiner Umgebung und weitere Gruben und Gebiete wurden erschlossen. 1720-1750 erreichten die Freiberger Gruben ein Silberausbringen von 6.000 kg im Jahr (!). Grund hierfür waren neue zentralisierte Verwaltung, Qualifikation der Berg- und Hüttenbeamten und verbesserte Technik. Es wurde eine "Stolln und Röschenadministration" ins Leben gerufen. Das System der Röschen, Bergwerksteiche und Aufschlagwässer wurde verbessert und der Bau des Aquädukts der Grube "Anna samt Altväter" brachte technische Verbesserungen sowie ein höheres Silberausbringen.

Nach dem Hubertusfrieden wurde Sachsen wirtschaftlich und staatsintern energisch reformiert. Männer wie Heynitz und Oppeln modernisierten das Montanwesen in Freiberg und Sachsen. Der Freiberger Bergbau erlebte einen neuen wirtschaftlichen Aufschwung, das Silberausbringen lag bei 3.000 kg im Jahre 1760 und bereits bei 11.500 kg im Jahre 1800. Die Ursachen hierfür waren das Auffinden neuer Lagerstätten, so z.B. "Beschert Glück", "Himmelsfürst", "Alte Hoffnung Gottes", "Kühschacht", "Segen Gottes und Herzog August" und viele andere sowie weiterer Einsatz neuer Technik (Schießen aus dem ganzen, ungarische Hunte, zusätzliche Wasserräder und Einbau erster Wassersäulenmaschinen ("Siegfried")). Desweiteren wurden neue Langstoßherde zur Trennung des Erzes eingesetzt und Kahnhebehäuser (die ersten Schiffshebewerke der Welt) erbaut und genutzt. 1775 wurde die Bergschule und 1765 ...

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...

Min­er­al Por­trait - REE - Rare Earth El­e­mentsThis is the most comprehensive synopsis related to the history, the mineralogy, the exploitation and the most actual economic and political resumé on rare earth elements and their minerals to be found in the internet. REE belong to the most important raw materials of the 21st century, which are used in a large number of key technologies. However, due to the fact that almost 97% of the world's REE are mined and produced in China, REE have become an ongoing political issue, mainly amongst technology providing countries like the US, Japan and Western Europe.

This portrait tries to explain the characteristics of REE and their role for our modern world. Written and investigated by Peter Seroka. (Article in german)

Min­er­al por­trait calcite... Among the most spectacular finds are the fantastic light blue calcites from the Julia mine in Bilbao, which enraptured collectors' hearts to about the mid-1970s. At about the same time the zinc mine Las Manforas at Aliva supplied excellent, highl lustrous Calcites, often associated with the world's best red Sphalerites. ...

Amonsgt the forms of calcite the pinacoid is unique as it consists of exactly two parallel and oriented perpendicular to the c-axis surfaces. All other Calcite forms have either six or twelve areas. The pinacoid is an open form, with which it can not really include space; so the pinacoid must accompany other forms on the calcite crystal ...

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.

Rosia Mon­ta­na (Veres­pa­tak), Ro­ma­niaThe village and the mine with the same name "Rosia Montana" are located approximately 85 km north of the city of Deva. The mine complex extends over 21.2 square kilometers and is one of the largest gold deposits in Europe. The tunnel system in the underground is several hundred kilometers long and was used until a few years ago. Already in Roman times the tunnels had a length of 145 km.
