Abstract

Two fully cored boreholes, the Rødryggen-1 and the Brorson Halvø-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 (Rødryggen-1 borehole) and near the uplifted crest of the rotating fault block (Brorson Halvø-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.
格陵兰东北部沃拉斯顿福尔兰 Rødryggen-1 和 Brorson Halvø-1 全取心钻孔(上侏罗统-下白垩统)--介绍
分别于 2009 年和 2010 年在格陵兰东北部的沃拉斯顿福尔兰(Wollaston Forland)钻探了两个全芯钻孔,即 Rødryggen-1 和 Brorson Halvø-1。其目的是测试上侏罗世-下白垩世泥质岩为主的演替在发育中的半地堑同一断块内两种不同环境下的地层发育情况:中央(Rødryggen-1 号钻孔)和旋转断块隆起峰顶附近(Brorson Halvø-1 号钻孔)。钻探出的矿床相当于西北欧、西伯利亚和加拿大东部沿海含油盆地的主要石油源岩序列,并为原北大西洋地区海洋脱氧的一个重要阶段提供了新的记录。
