  • Four main geological sequences have been established: Cenozoic (1.9 to 2.8km/s)| Cretaceous (3.2 to 4.0km/s)| lower to middle Mesozoic (4.5 to 5.0km/s)| pre-Mesozoic (5.4 to 6.3km/s). These agree broadly with the adjoining western approaches

  • The Lateglacial is in geological terms very short and in absolute chronology closely defined. Within north-west Europe planktonic foraminifera are rare or absent and study is consequently confined to bottom-dwelling species. As these species

  • general hydrodynamical behaviour. The model that gives the most satisfying reconstitutions of the observations points out a seepage situation which fits quite well to the known geological conditions of the aquifer. (The AA).

  • of ice with a debris concentration of 1%, or about 1200 yr for a 1.5% debris load. Another meltout curve, based on seismic data, suggests total meltout in about 875 yr. When all geologic factors are considered, the empirical meltout curve is remarkably

  • account for the remainder. The documented erosion in part substantiates W. A. White's (1972, Geological Society of America Bulletin 83, 1037-1056) hypothesis of deep erosion and exhumation of shield regions, but is not in agreement with the entire volume
