Micropalaeontology of the NW European continental shelf.
Sediment distribution on the British Continental Shelf R. E. Eden and J. E. Wright.
Sediment distribution on the British continental shelf has been studied as part of the marine survey of the Institute of Geological Sciences, and published data from other workers, have been incorporated into a compilative map. To date, representative sediment samples have been collected by IGS from nearly half of the total shelf area, using grabs, vibrocorers and gravity corers. Over wide tracts the topmost sediments are thin, denoting a recent change in sedimentary facies. It is generally possible to set up a sequence for the underlying post-glacial sediments, but details of glacial stratigraphy offshore are obscure in many areas, although drilling by MV Whitethorn and commercial operators is producing some useful results.
The value of ostracods in continental shelf studies J. Neale.
Ostracods provide a valuable tool in continental shelf studies and may be used in a number of ways. In Mesozoic rocks (other than non-marine Triassic) they provide an excellent means of correlation and the 'classical' biostratigraphical approach is generally of paramount importance whilst ecological considerations are often secondary. Conversely in Pleistocene and Recent studies the vastly different time scale ensures that the ecological approach is often the more rewarding. The Tertiary systems occupy an intermediate position in this respect.
