Elisabeth I pit

Broken shaft of the Elisabeth mine

The Elisabeth I. mine was one of the few manganese ore mines in the Sauerland , near the town of Rösenbeck . The iron-manganese ore was mined here from 1918 to 1936 and from 1943 to the end of the Second World War .

history

Manganese ores have been mined in the northeastern Sauerland since the 18th century. Small pinge trains , which are located east of the Rösenbeck cemetery, bear witness to early attempts at mining for manganese . Northwest of Madfeld there are references in the authorization files to a 15 m deep test shaft in the former Antonius mine field , awarded on June 26, 1918. References to a small, ineffective test mine , which, however, was assessed as a failure overall. The search for manganese ores intensified in the first decades of the 20th century after the importance of manganese as a steel refiner was discovered. Rösenbeck numerous mine fields on manganese - in this period were around Madfeld awarded Ludendorff, Sophie studs (1913), Louise Elizabeth I (1896), (1917) and Anthony (1918) (ns.).

Operation time of the Elisabeth I.

The manganese mineralization, which was mined in the Elisabeth I mine, is bound to an intensive tectonic fault zone in Upper Devonian and Lower Carboniferous slates and limestones between two thrust tracks in the Rösenbeck Mulde. The irregularly formed ore deposit dips at 10 to 50 ° and is on average 2 to 3 m thick, more rarely up to 20 m thick. The lumpy, iron-containing manganese ores, in a clay matrix are embedded, composed mainly of a mineral Paragenesis of pyrolusite , goethite and limonite . The rich ore parts had a maximum iron content of 30% and manganese content of 20%. The Elisabeth I mine was developed between 1918 and 1922 with the help of mining shafts. The mineralization was formed in the area of ​​the tectonic faults and as a nest-like enrichment in the Kulm silica limestone.

After around 7000 t of ore had been extracted from 1922 to 1936, the Elisabeth I mine was abandoned in 1936 due to its low productivity. Operations were resumed in 1944 due to the shortage of raw materials. Geological and geological investigations, as well as inventory calculations, were carried out by Werner Paeckelmann and Kurt Fritz in September 1944 on behalf of the Reich Office for Soil Research . Based on these calculations, it was assumed that a lenticular ore body with around 50,000 t of iron-containing manganese ore could still be mined. The re- installation of the mine began in 1943 with the sinking of a 43 m deep main shaft . The mine workings extended from 1944 three soles : the bearing sole (20 m), the conveyor bottom (34 m) and the water Great sole (56 m). After the end of the Second World War, operations were discontinued and in 1948 the extraction shafts and the weather shaft were filled with tailings . T. has fallen.

Ore genesis

The iron-manganese mineralization was from descendants (descending) ore solutions during Tertiary ( Oligozän to Miozän formed). The iron and manganese compounds originate primarily from the sub-carbonic rocks, which primarily had a higher iron and manganese content. During the profound tertiary weathering , these compounds were loosened and transported down again in tectonic, strongly disruptive zones and again concentrated in excretion.
