At the geothermal research platform Gross Schönebeck (NE German Basin), we analysed 3-D seismic reflection data to determine the degree and direction of azimuthal velocity anisotropy which is interpreted as the effect of sub-vertical fracturing. Above the Zechstein salt, the observed anisotropy roughly correlates to fault structures formed by an upwelling salt pillow. Below the salt, faults are not obvious and the direction of less pronounced anisotropy and interpreted fracturing follows the trend of the regional stress field. The fracturing in an extensional setting above salt pillows may cause higher permeability and better conditions for geothermal exploitation. © 2023
