The Geology of the Land between Ekmanfjorden and Dicksonfjorden in Central Vestspitsbergen

Abstract

The peninsula between Ekmanfjorden and Dicksonfjorden has been mapped geologically. Devonian sandstones are overlain unconformably by a Permo-Carboniferous sequence of limestones (200 m.) and dolomites and gypsum (300 m.). This is followed by more than 150 metres of Permian cherts. The strata show a slight but consistent dip towards the SSE. A fault having the trend of this dip has been proved in Ekmanfjorden. Sills are intruded in the higher levels of the succession and it is suggested that the intrusions are contemporaneous with the faulting. By comparing the lithology the area can be correlated with the known sections of Billefjorden and Kongsfjorden.
