ABSTRACT: Revision and Update of the Stratigraphic Nomenclature of Netherlands

In 1991, the Geological Survey of the Netherlands started a project for revision and updating of the pre-Quaternary lithostratigraphy of Netherlands. This had not been done systematically since 1980. Main objectives of the study are (1) to bring the lithostratigraphic ideas into agreement with new findings and increased knowledge of Dutch subsurface geology (lithostratigraphy was extended into the Lower Carboniferous and Devonian), (2) expansion and standardization of the definitions and descriptions of existing lithostratigraphic units, (3) application of modern concepts (e.g. sequence stratigraphy) in order to describe better the distribution of reservoir-prone sediments, and (4) to reach consensus on a number of stratigraphy-related subjects, such as a chronological time frame, app ication of biozonations, and the designation of the behavior of main structural elements through time.

Eight working groups were formed, each working on a specific aspect or stratigraphic interval, under the supervision of a steering committee. Both working groups and steering committee were composed of persons from the Geological Survey, several leading oil companies and, in some cases, universities.

Several working groups have completed their tasks, and updates of these stratigraphic intervals are available at the conference. Posters will display stratigraphic updates of lithostratigraphy for the Carboniferous, Zechstein, Lower Triassic, and Upper Jurassic-Lower Cretaceous.
