Palynology of Rhaetian, Liassic and Dogger strata in the Eastern Netherlands

Abstract

Rhaetian, Liassic and Dogger sediments have been examined palynologically from boreholes, mainly located in the Achterhoek area, eastern Netherlands. The results are presented in seven pollen diagrams and a distribution chart; seven pollen zones have been recognized and illustrated (6 photoplates). A range chart of selected palynomorph types has been designated, covering the uppermost Triassic-Dogger strata. Some concluding remarks concerning Liassic tectonic movements are made.
