Grube Cä­cilia im Wölsen­dor­fer Re­vi­er1936 erwirbt die Firma "Saline Ludwigshalle AG", Bad Wimpfen, die Grube Kallmünzer. Daraufhin wurde der Firmenname ( Besitzer) in "Flußspatwerk Schwarzenfeld GmbH, vorm. Anton Kallmünzer" geändert. Die Flußspatgrube wird von nun an Grube Cäcilia, teils auch Grube Cäcilie, genannt. Anton Kallmünzer bleibt Teilhaber und Geschäftsführer.
Schacht Cäcilia II ist mit 86 m Teufe Hauptförderschacht. Der Schacht Marie, ehemals zu Grube Freiung II zugehörig und der Reichhart-Schacht, ehemals Grube Freiung I, werden als Wetterschächte genutzt. Im gleichen Jahr erwirbt die Firma auch das Ausbeuterecht ... Ein Beitrag von Michael Kommer

The Ts­in­gys of Mada­gas­carOne of Madagascar's geological specialties are the so-called Tsingy: bizarre, at first sight hostile Karst landscapes, though form, due to the inaccessibility, a refugial area for some species. The word Tsingy means "walking one tip-toes" or "where one cannot walk bare-foot" in Malagasy language, an accurate description for the partially razor-sharp rock formations which can reach 20 m in height and with ends which can be as thin as pencils.

Best known and most impressive are the Tsingy of Bemaraha in the West of the island and the Tsingy of Ankarana in the North, both widespread Karst areas. In the North, as well, about 10 km south of the city of Antsiranana, one can find the Red Tsingy which have been washed out of the lateritic layer of earth.

Min­er­al Por­trait CalciteCalcite 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. 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.

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...

Ra­man-Spek­troskopie / RSBei der Raman-Spektroskopie wird die zu untersuchende Probe mit monochromatischem Licht (üblicherweise einer leistungsstarken Laserquelle) bestrahlt. Das Spektrum des an der Probe gestreuten Lichts wird gemessen. Ein sehr kleiner Teil des zurückgestrahlten Lichts weist Frequenzunterschiede zum eingestrahlten Licht auf (Raman-Shift). Diese entsprechen den für das Material charakteristischen Energien von Rotations-, Schwingungs-, Phonon- oder Spinflip-Prozessen. Der Raman-Effekt kann weitgehend symmetrisch im längerwelligen (Stokes-Seite) oder kürzerwelligen (Anti-Stokes-Seite) Bereich beobachtet werden. Vielfach wird nur ein Bereich (die Stokes Seite, also längerwellig) gemessen um den apperativen Aufbau in Grenzen zu halten...

Ore leach­ing (in ger­man)The metal extraction by ore leaching (mostly copper) was about 1,000 years BC. known in the Mediterranean, but there are also barely no written records. The in the Middle Ages and in the following Renaissance well-known different procedures were first described in detail by Georg Agricola 1556 in his book "De Re Metallica Libri XII".

Dev­il's Pul­pitActually, this is a picturesque place in a well-kept forest. Nevertheless, in the past, evil itself is said to have preached to the damned here from a large, solitary, towering rock spur. Today, the term Devil's Pulpit inspires one to play with associations, as do the drawings of agates found here. Their fantastic outlines, coupled with the unusual shape of the secondary rock, evoke images in the viewer that he would not have suspected in a stone. And on the devil's pulpit no longer an evil demon is waiting for the agate collector, but other executive powers threatening with purgatory... a contribution by Klaus Schäfer and others (in german)
