Internal thermal anomalies in sedimentary basins caused by salt structures Ben Norden Salt structures like salt pillows and salt diapirs are quite common in sedimentary basins Observable features: thermal anomalies The thermal conductivity of rock salt is a factor of 2-3 higher than that of the typical surrounding rocks Zones of special interests for the geothermal exploration?

Internal thermal anomalies in sedimentary basins caused by salt structures The knowledge of the salt structure geometry and the thermal properties of the involved rocks play a decisive role in the evaluation of a specific site.
