Texture and mineralogy of 27 gravity cores and 20 grab samples from the Malangsdjupet area are described. In the western trough and on the slopes lies a frrm pebbly mud (till ?) overlain by glaciomarine sediments and a 2-15 cm Holocene sand; in the depressions in the east there are 1-2 m of Holocene poorly sorted sand and mud. Mudrocks of Lower Cretaceous age were eroded just before deposition of the Skarpnes moraine (12,000-12,500 BP) and are the main source for the pebbly mud. Winnowing after withdrawal off the ice formed a grav el lag 14C dated to 11,900 ┬▒ 260 BP.
