Fluid inclusion evidence for a Cretaceous-Palaeogene petroleum system, Kangerlussuaq Basin, East Greenland
Petrographic and fluid inclusion studies of sandstone samples from the Cretaceous–Palaeogene Kangerlussuaq basin reveal the presence of oil inclusions as secondary trails across grains. Fluid inclusion petrographic and microthermometric investigations suggest that oil was trapped at temperatures in...
