Abstract

A stratigraphie section of the Kattegat, from Lâsô, Denmark to Billdal, SW Sweden, has been investigated, using hydroacoustic techniques complemented with bottomsampling. A transition occurs, from a predominating Precambrian bedrock surface in the east to Mesozoic strata in the west. The Djupa Rànnan channel separates these two bedrock provinces. Glacigenic deposition, also the late Weichselian and Holocene sediments, has been influenced by the various bedrock configurations. Gas is widespread in the Holocene sediments, rich in organic content.
