摘要：

Two fully cored boreholes, the Rodryggen-1 and the Brorson Halvo-1, were drilled in Wollaston Forland, North-East Greenland, in 2009 and 2010, respectively. The objective was to test the stratigraphic development of the Upper Jurassic - Lower Cretaceous mud-dominated succession in two different settings within the same fault block of a developing half-graben: centrally (Rodryggen-1 borehole) and near the uplifted crest of the rotating fault block (Brorson Halvo-1 borehole). The drilled deposits are equivalent to the principal petroleum source-rock sequence of the petroliferous basins of North-West Europe, Siberia, and basins off eastern Canada and provide a new record of an important phase of marine deoxygenation in the proto-North Atlantic region.
