Eustatic cycles around the Devonian-Carboniferous boundary and the sedimentary and fossil record in Sauerland (Federal Republic of Germany)

A review of the sedimentary and fossil record around the Devonian/Carboniferous (D/C) boundary in Sauerland at the northern border of the Rhenish Slate Mountains forms the basis for the recognition of a succession of relative sea level changes in that area. This transgression/regression (T-R) curve shows a remarkable similarity with the one constructed for the La Serre D/C boundary stratotype (Montagne Noire, France). It is therefore suggested that these T-R curves are closely related to global (eustatic) sea level changes. -Authors
