Calcareous nannofossil Biozonation of the Tertiary of the North Sea Basin

Gallagher, L. T.

Abstract

Tertiary material (739 samples) from 12 released Shell/Esso exploration wells from the central and southern North Sea Basins (see Fig. 1) was studied to elucidate the distribution and character of calcareous nannofloras in this commercially valuable area. A biozonation comprising 23 zones was erected for the Pliocene-Palaeocene interval and comparisons are made with existing schemes and between different geographical areas.
