Salt tectonics plays a major role in many
sedimentary
basins. One of the classic areas of salt tectonism is the Central
European
Basin
hydrocarbon province were mobile Permian Zechstein salt formed a large number of salt walls, diapirs and
pillows each formed by a distinctive interaction of tectonism and sedimentation. Our study is the first which quantitatively
relates the Paleozoic to present day kinematics of the
basin
, salt diapirism and
sedimentary
response. We use seismic
interpretation, based on prestack depth-migrated 2D and 3D seismic data, and retro-deformation to obtain a better
understanding of salt tectonics, structural control, and
sedimentary
response in the german part of the
basin
.
Several salt wedges formed by lateral extrusions during periods of diapir emergence and reduced sediment accumulation
can be identified. High resolution mapping and well-log
analysis
of the
sedimentary
stacking patterns displays the effects of
syn-
sedimentary
salt movement that is consistent with the regional
sedimentary
, structural and stratigraphic framework.
These near-diapir sequences which distinctly record salt-sediment interaction bear a number of potential hydrocarbon traps
and present an excellent model for other salt-rich hydrocarbon systems.
Better understanding of the structural,
sedimentary
and salt tectonic evolution and improved knowledge of the position and
amount of salt has furthermore effects on seismic modelling and depth conversion and advances the prediction of potential
reservoirs in the sub-salt sequences.
