Abstract

The Kupferschiefer districts in Central Europe contain some of the world’s highest-grade sediment-hosted stratiform Cu (SSC) deposits (see Borg et al., 2012). The high-grade sulfide mineralization in the organic matter-rich marine mudstones of the Kupferschiefer (T1), and also in the underlying continental sandstones of the uppermost Rotliegend (S1) and overlying Zechstein Limestone (Ca1), in the Saale subbasin (Eastern Germany) are dominantly formed as a replacement of calcite cement (Mohammedyasin et al., 2023).

We provide carbonate major element chemistry, carbon isotope composition of organic matter, and calcite carbon and oxygen isotope microanalysis datasets of drill core samples from the Saale subbasin in Eastern Germany. The samples include the uppermost Rotliegend sandstone (S1), Kupferschiefer (T1) mudstones and lowermost Zechstein Limestone (Ca1), referred as the Kupferschiefer system, from three drill cores (Sangerhausen, Allstedt and Wallendorf).

For further details, see Mohammedyasin et al. (Chemical Geology, when available).
