Summary:
A high-resolution P-wave vibroseis reflection survey and PSDM processing are used to image the structure of the Tannwald Basin, a 250 m-deep, distal branch basin of the Rhine Glacier. The basin substratum, the basin base, as well as the basin infill could be identified. The subglacial deposits (e.g. till) can be clearly distinguished from basin fines (e.g. marl, silt and sand). We identified five seismic facies as well as a number of subfacies. Internal features of the basin comprises an allochthonous Molasse block and a system of eskers in section. The interpretation will be used to locate a drill site for the ICDP-project DOVE and provides information for S-wave and multi-component processing.
