Mansfeld mining district (Permian of Germany)

Also known as Mansfelder Revier, Mansfelder Mulde, Mansfelder Land, Kupferschiefer, Copper Shale, Wolfsschacht, Otto-Schacht

Where: Saxony Anhalt, Germany (51.5° N, 11.5° E: paleocoordinates 16.1° N, 23.3° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Kupferschiefer Member (Werra Formation), Wuchiapingian (259.9 - 254.2 Ma)

• The Kupferschiefer (T1) is the basalmost unit of the Werra Formation (Z1), the latter being the basalmost formation of the Zechstein Series (Uppermost Permian of Central Europe).

•Brauns et al. (2003) reported a date of 257.3±1.6 Ma (Late Permian/Lopingian: Wuchiapingian) for the Kupferschiefer based on a Re-Os geochronological study. The presence of the conodont Mesogondolella britannica in Kupferschiefer equivalents supports a middle Wuchiapingian age for the Protorosaurus-bearing levels (Legler et al. 2005, 2008).

• member-level stratigraphic resolution

Environment/lithology: offshore; lithified, black claystone

• Deposition took place "below wave base in a stratified water body (Paul, 1986a)" (Becker & Bechstädt, 2006, Sedimentology 53, pp. 1083–1120)

•"Sedimentation rates during Kupferschiefer deposition were low (5 mm kyr)1; Füchtbauer, 1968). The Kupferschiefer is thus interpreted as a condensed section, which formed during maximum flooding (Ross & Ross, 1995; Strohmenger et al., 1996a)." (Becker & Bechstädt, 2006)

Size class: macrofossils

Collection methods: surface (float), mechanical,

• The fossils come from the spoil heaps of the copper mines.

•GM = Geiseltalmuseum of the Martin-Luther-Universität, Halle/Saale, Germany

•SSWG = Geological Institute of the Ernst-Moritz-Arndt-Universität, Greifswald, Germany
