Grube Käfersteige, Würm, Pforzheim, Regierungsbezirk Karlsruhe, Baden-Württemberg, Deutschland
Fluorite-quartz vein deposit, hosted in bunter sandstones along the suture zone between the Moldanubian and Saxothuringian units of the Hercynian fold belt. The vein trends ENE, is either vertical or dips steeply to the north and extends over a strike length of 250-1500m. Its thickness varies from 5-30m. To the north, it is bounded by a clay gouge which is up to 15m thick.
Located between Würm and Tiefenbronn, about 7.5 km SE of Pforzheim. The mine was closed by the end of 1996 because of decreasing industrial demand for fluorite. Since spring 2005, it was being prepared to be re-opened. As of 2007 it is closed.
Currently (2026), the mine is scheduled to re-open in 2027 by the Deutsche Flussspat GmbH (https://www.deutsche-flussspat.de/news/dfg-startet-sicherheitsrelevante-massnahmen/ and https://www.mineralienatlas.de/forum/index.php/topic,65475.msg424490/topicseen.html#new).
