Abstract

A Middle Oxfordian to Volgian sequence stratigraphic model for the Greater Shearwater area is presented. This model builds on the genetic stratigraphic sequences of Partingtonet al.(1993b), refining the position of key stratigraphic surfaces with an additional emphasis on sequence boundary description. Most stratigraphic surfaces are believed to be related to tectonic events superimposed on a gradual rise in relative sea-level from the Middle Oxfordian to Volgian. Biostratigraphic information drawn from throughout the UK Central Graben allied with regional log correlation and seismic data has allowed a robust sequence stratigraphic framework to be developed which is applicable to the Greater Shearwater area.
