Steinbruch Asbeck, Limestone quarry in Balve, Germany.

Steinbruch Asbeck is a limestone quarry in Balve with steep walls of exposed rock layers from different time periods. The site displays varied sediment formations with contrasting mineral compositions that become visible in the exposed stone faces.

The quarry extracts Massenkalk from the uppermost Middle Devonian and lowest Upper Devonian in banked facies. It belongs to Rheinkalk, a subsidiary of the Belgian Lhoist group, the world's largest producer of lime and dolomite products. In 2020 the Arnsberg regional council draft excluded an eastern expansion into the Beil area with its seven protected biotopes; a southern expansion of about 40 ha toward the Beckumer Feld was proposed instead, requiring removal of Kreisstraße 29 to Eisborn.

The quarry is owned by Rheinkalk, a subsidiary of the Belgian Lhoist group, the world's largest producer of lime and dolomite products. The rock is crushed on site and carried by conveyor belt to the processing plant in Oberrödinghausen, where it is burned into lime. Since 2019 the Museum für Naturkunde in Berlin has sought protection for the eastern expansion area around Das Beil, one of Europe's notable palaeontological sites.

The quarry is an active industrial site, not open for walking; the only public access is the observation platform north of Eisborn, from which visitors look down into the pit. The site lies southeast of Oberrödinghausen and west of Eisborn in the Hönnetal, in the Märkischer Kreis.

The quarry's rock layers are largely reddened by hematite, which also coloured many of the minerals found here. The site belongs to Rheinkalk, a subsidiary of the Belgian Lhoist group, the world's largest producer of lime and dolomite products. Crushed on site, the stone travels by conveyor belt to the processing plant at Oberrödinghausen.
