A preliminary seismic study of part of the pre-Paleocene section offshore southern West Greenland between 66°N and 68°N

Seismic data acquired during the 1970s in an area betweeen 66° and 68°N offshore West Greenland have been reinterpreted. The present report concerns the pre-Paleocene section where four major seismic units have been identified. Seismic facies analy sis of the youngest unit suggests that it was deposited by a south-westward prograding wave-dominated delta, the development of which was probably controlled by eustatic changes in sea level. The unit underlying the delta unit is interpreted as shales deposited in a deep-marine environment. Thus a possible target for hydrocarbon exploration has been identified.

The deepest unit has been affected by normal faulting in response to extensional stresses. If reservoirs and seals are present within this unit, structural traps could be generated by the major fault blocks which are situated in a sub-basin some 30 km by 100 km.
