摘要：In 2011, traces of bitumen in the 1160 Ma old Ilímaussaq intrusion in South Greenland have been examined in order todetermine their origin. The investigation was prompted bythe recent interest in hydrocarbon exploration off westernGreenland, an interest expressed in the form of four new licences in the region (Christiansen 2011). The hydrocarbonpotential in the region was realised after reinterpretation ofseismic profiles across the Labrador Sea, and this indicatesthe presence of a sedimentary basin off south-western Greenland (Fig. 1; Chalmers & Pulvertaft 2001). However, themain problem in petroleum exploration off south-westernGreenland is that no prolific marine source rocks have beendemonstrated (Christiansen 2011). Therefore, any trace ofhydrocarbons, however small that may help demonstrate theoccurrence of source rocks in the region, deserves careful examination.
