Stratigraphy in Billefjorden trough

Gipsdalen Group

Billefjorden Group: 0-450 m, Visean or older

Andree Land Group: Wood Bay Fm. A mixed and multi-colored sequence of clastics from shales to conglomerates. Cleavage and fairly complex deformation just W of the BFZ makes recognition of stratigraphic units more difficult. Lamar & Douglas (1995) describe lithologies and formational stratigraphy in much more detail. The interpretation is of coastal plain fluvial environments close to sea level with occasional flooding introducing estaurine and marine influences.

Basement: various schists, gneisses, amphibolites and minor quartzite and marble interbeds as part of the Atomfjella Group (McCann & Dallmann, 1996).
