Kupferschiefer
Quick Summary
The Kupferschiefer is a type of bituminous shale found in eastern Germany and Poland. This black shale is notable for containing abundant organic matter and pyrite, and in some locations, it holds significant concentrations of copper, lead, and zinc.1
These mineral deposits are of commercial interest and are mined for their valuable metals. The formation of such stratiform deposits is often linked to hydrothermal solutions, which are hot brines capable of dissolving and transporting ore minerals. These solutions can deposit minerals in specific strata, often within shales that contain organic matter and pyrite. The exact origin of these deposits can be a subject of debate among geologists.12
