Raw materials in the Femer Bælt area. A summary report

This technical report has been prepared as part of the Environmental Impact studies of the Fehmarn Belt Link Feasibility Study, Phase 1, on behalf of the Fehmarn Belt Project Organisation, comprising the “Trafikministeriet”, Denmark and “Bundesministerium für Verker”, Germany.

The report is a summary of a confidential report (Råstofgeologiske og Geologiske undersøgelser i Østersøen. Femer Bælt, område 564) prepared by GEUS (Jensen 1996) on behalf of the Danish National Forest and Nature Agency.

In addition, investigations on sand resources in Fehmarn Belt undertaken by the “Bundesanstalt fur Wasserbau” in 1965 are included (Bundesanstalt fur Wasserbau 1965).

A general evaluation is presented of sand and gravel raw materials in the German and Danish sector of Femer Bælt as potential resources for a Fehmarn Belt Link project.

The main results are based on mapping and research made by GEUS in co-operation with the German research institute “Institut für Ostseeforschung Warnemünde".

The detailed geological interpretation of seismic and lithological data is not included in this report, but has been and wiil be published in scientific papers (Jensen, J.B., Kuijpers, A. & Lemke, W. 1996, Jensen, J .B., Bennnike, O., Witkowski, A. Lemke, W. & Kuijpers, A. accepted, Lemke, W., Jensen, J.B., Bennike, O. & Witkowski, A. accepted).

The contents of the report can be subdivided in 3 main parts, i.e. 1) an introductory methods and geological part, 2) description of seabed sediments and seabed dynamics and finally 3) the raw material evaluation.

Although for the geologically skilied person it is important to understand the depositional history of the raw materials and the actual seabed dynamics, other readers may confine them selves with the chapters dealing specifically with the raw materials.
