Abstract: | The geothermal fields in the Pericaspian, Pripyat, and North German basins are considered. These basins are characterized
by widespread Upper Paleozoic evaporite sequences, which underwent halokinesis with the formation of salt domes and plugs
owing to tectonic and gravity instability. Heat flow refraction occurs at the boundaries of the domes with country rocks due
to the contrast in thermal conductivity of evaporites and terrigenous rocks between the domal zones. This is the main cause
of heat flow variation in the lateral and vertical directions in the salt-dome basins. Close correlation between zones of
elevated temperature in the sedimentary rocks and petroleum occurrences is confirmed by the results of 2D and 3D modeling
of the geothermal field. The previously noted relations of oil and gas fields to the deep faults in the studied basins create
prerequisites for consideration of the geothermal field as a genetic factor controlling the tectonic features and petroleum
resources of the salt-dome basins. |
