Preface

In June 1989, Dansk Olie- og Gasproduktion A/S (DOPAS) sponsored a well-attended symposium on the Jurassic in the Southern Central Trough held at the DOPAS premises in Hørsholm, Denmark. The background for the symposium was a desire among geologists working in the Dutch, German and Danish sectors of the North Sea to establish a forum to discuss problems of lithostratigraphic correlation across the sector boundaries and eventually arrive at a common nomenclature. A number of lectures were held at the symposium and an informal working group was established to deal with the details of lithostratigraphic correlation. The present publication, sponsored partly by DOPAS and partly by the Geological Survey of Denmark (DGU), contains extended abstracts of the lectures.
