A long standing puzzle is tied to the geology of the Oslo Rift's seaward continuation into the northern Skagerrak. In previous studies it has been suggested that this part of the graben consists mainly of magmatic and plutonic rocks. Interpreting seismic refraction data from the M/V Mobil Search cruise in winter 1987, we found velocities typical of Cambrian-Silurian sedimentary rocks in areas claimed to consist of plutonic rocks. Also velocities in the basement outside the Skagerrak Graben proper coincide with similar observations within the land ward Larvikite (plutonic) rocks. Corresponding Bouguer gravity observations were modelled accurately without invoking anomalous intruded magmatic material in the crust beneath the Skagerrak Graben. The conclusion is that the entire seaward part of the Oslo Rift, from the Vestfold Graben in the north to the Fjerritslev Fault Zone in the south, constitutes a single structural element and, as such, aptly is named the Skagerrak Graben. |
