Paleogene foraminifera of the Central and Southern North Sea, and their Biostratigraphical application
This thesis examines the Microfauna of the North Sea Palaeogene, particularly the foraminifera, and their biostratigraphical applications in the Central and Southern North Sea. A biostratigraphical scheme has been erected for calcareous benthic (CB Zones 1-15), agglutinated benthic (AB Zones 1-11b)...

Summary: | This thesis examines the Microfauna of the North Sea Palaeogene, particularly the foraminifera, and their biostratigraphical applications in the Central and Southern North Sea. A biostratigraphical scheme has been erected for calcareous benthic (CB Zones 1-15), agglutinated benthic (AB Zones 1-11b) and planktonic foraminifera (PK Zones la-13, utilising diatoms and radiolaria where necessary), which was then combined into one scheme using the previous 3 'groups'. The Shell Expro. U.K. computer was used to draw up rangecharts of these 'groups', and each well is described in the text and in 'Distribution charts' (See Enclosures Nos. 1-10, plus Rangecharts in pocket). The for amini feral biozonation of this thesis is correlated with NSP (North Sea planktonic) and NSB (North Sea benthonic) Zones of King (1983, 1989), the P Zones of Berggren et al. (1985), the sedimentological sequences of Stewart (1987) and the nannoplankton zones of L. Gallagher in his Ph.D. thesis. A canbined biostratigraphic scheme, utilising both foraminifera and nannoplankton was proposed in Gallaghers thesis and is discussed here. |
