Abstract
The shallow sedimentary sequence in Flemish Pass, a small perched basin along the north-eastern Grand Banks margin, was studied for improving the knowledge of timing of glaciation, and its influence on slope and basin sedimentation, using high-resolution seismic profiles and 10 m long piston cores. A new basin-wide seismic stratigraphy was defined and calibrated by multiple dating methods. The spatial and temporal extent of mass transport deposits (MTDs) was used to understand the impact of ice sheets on sedimentation in Flemish Pass. Grain size analyses from sandy beds indicate turbidite and contourite activity in the basin. More turbidites were deposited during Greenland stadials, more contourites during interstadials, which may link to the oceanic regime. From the temporal and spatial distribution of MTDs and turbidite sands, different initiating processes have been proposed.
