The Giershagen Coelesting Mine was an ore mine in Giershagen in the eastern Sauerland in North Rhine-Westphalia , where the strontium mineral coelestin was mined in small open-cast mines and mining pens at the beginning of the 20th century . The presence was one of the few strontium - deposits that were developed in Germany. The last operating period ended after the Second World War .
geography
Geographical location
The Coelestin pit is located north of the village at the eastern exit of the Mühlental.
geology
There were different geological ideas about the formation of the Giershagener Coelestin. The first investigators viewed the celestial formations as mineralizations that were precipitated from ascending hydrothermal ore solutions . Werner Paeckelmann, on the other hand, sees celestial mineralization as a facial representation of gypsum formations in the edge areas of the Zechstein Sea .
Today it is assumed that celestine was precipitated from highly concentrated marine waters of the marginal Zechstein Sea in bays that were cut off by the fresh water supply. The mineralization is bound to mudstones of the Werra-Staßfurt boundary clay and the Staßfurt carbonates of the Zechstein , which directly overlay the folded Paleozoic basement at Giershagen .
history
Celestine was around Giershagen since 1892 by the German Coelestingesellschaft GmbH initially by trial pits explored and mined since 1895 in an attempt operation, however, came to a standstill after a short time. Another attempt at dismantling was started in 1903. For this purpose, trenches and shafts were created to explore the geology and the supply of the deposit. The handpicked celestine obtained in Giershagen was processed in Obergembeck and had strontium sulphate contents of over 90%.
Towards the end of the Second World War, due to the worsening raw material situation, the deposit was again assessed by geologists from the Reich Office for Soil Research . Celestine was used as one of the few minable strontium minerals in pyrotechnics and in the manufacture of tracer ammunition . The average thickness of the celestial deposit is given as 1 to 1.50 meters, and nest-like accumulations could also be observed. The deposit extended over a length of 500 meters and 15 to 25 m width and was largely developed by prospecting. The camp was dismantled in the last months of the war by prisoners of war and evacuees who were housed in a barrack camp in Giershagen. A new process had to be developed for the preparation of the Giershagener Celestine, which, however, could no longer be technically implemented due to the war. Various processing methods were tested at the Bergakademie Clausthal using mineral samples.
The small deposit only had a supply of 500 t and was classified as insignificant and uneconomical in a deposit reassessment in the 1970s.
