Abstract

In recent Black Sea sediments peculiar sediment layers occur which in sedimentological and geochemical composition differ from over- and underlying sediments. Originally described as turbidites they lack typical turbidite features. An alternative formation mechanism is proposed here and a conceptual model developed. This explains the occurrence of the so-called ‘Degens’-layers by density inversion eventually supported by exsolution of biogenic gas.
