A stable isotope study of pyrite formation in the Late Pleistocene and Holocene sediments of the Black Sea

The abundance and isotopic composition of total and pyrite sulphur have been determined in a core in the central Black Sea. Pyrite varies in concentration from roughly 2 wt% in the sapropel (Unit 2), to 0.8 wt% in the modern horizon (Unit 1) and ca. 0.1 wt% in the lowermost horizons of Unit 3 (Lake...

Zusammenfassung:The abundance and isotopic composition of total and pyrite sulphur have been determined in a core in the central Black Sea. Pyrite varies in concentration from roughly 2 wt% in the sapropel (Unit 2), to 0.8 wt% in the modern horizon (Unit 1) and ca. 0.1 wt% in the lowermost horizons of Unit 3 (Lake Beds). An intermediate mud-flow horizon and the upper part of the lake beds have similar values to those in the modern sediments. The degree of pyritization (DOP) is lowest (
