Ruhpolding marble
Ruhpolding marble is a culturally and historically significant stone that has been used in sacred buildings in southern Germany especially since the Middle Ages . The rocks of the Ruhpolding Formation were mined near Ruhpolding . Mining was abandoned in the early 1970s.
This marble is a limestone in the petrological sense and not a marble , but belongs to the so-called lump limestone . The name of this natural stone as marble has historical roots.
geology
During the Triassic period , the rocks of the Northern Limestone Alps were formed in a tropical flat sea on a continental shelf . About 200 million years ago the shelf broke and the sea divided swellings and basins in which sediments were deposited. 150 million years ago in the Upper Jura ( Malm ) the mainly reddish but also light gray colored Ruhpolding marble was created in the area of a submarine threshold. The deposition rates were low and the sediments that had not yet solidified were relocated. The deposited rock layers are colored differently. The Ruhpolding marble is in the form of thick, brownish-red nodular lime. Limestone with embedded crinoids (sea lilies) and cephalopods (ammonites) also occur in its vicinity .
Rock description
This limestone is red, red-brown to yellowish and light gray. The red variety, also known as red marble, used to be very popular. The rock consists predominantly of calcite, the crystallization forms of calcium carbonate (carbonate of calcium CaCO 3 ). Iron oxides occur in more or less fluctuating proportions, such as hematite , which is reddish to red, or limonite , which colors natural stone yellow to brown. Sometimes white veins occur and sea lilies and ammonites can be embedded.
Dismantling
The Ruhpolding marble was quarried in Ruhpolding from the early Middle Ages until around 1970. Today the quarry on Haßlberg near Ruhpolding is one of the 100 most beautiful geotopes in Bavaria. It is used as a climbing garden .
use
Due to its red to yellowish color, it was a popular building and decorative stone. Ruhpolding marble was used for sculptures, fountains, portals, grave slabs, balusters and banisters, baptismal fonts, window frames, columns and wayside shrines.
