Figure 4: Spatial variability in geometry of Fosses Dangeard depressions.
From: Two-stage opening of the Dover Strait and the origin of island Britain
(a) Three-dimensional perspective view of seismic profiles across north-west sector of Dover Strait study area showing geometry of depressions D and E. Depressions form localized features eroded in Cretaceous bedrock. Note presence of possible internal erosion surfaces within Fosses sediment infill. Vertical exaggeration ∼13. M, seabed multiple. (b) Geological interpretation of seismic profiles with details of Cretaceous bedrock into which Fosses are eroded. Locations of seismic profiles indicated in Fig. 3b. f, fault.
