Abstract


The depth to the bottom of magnetic sources (DBMS) is calculated from 31 overlapping blocks in Germany using Centoid method. The depth to the top of magnetic bodies varies from 1.49 km to 5.25 km in the region. The centroid depth and DBMS varies from 9.82 to 19.03 km and 19.9 to 33.98 km, respectively. The deeper DBMS are found corresponding to the North German Basin having lower heat flow values in the region. The inverse relation between the heat flow and DBMS is found. In general Moho depth is deeper than the DBMS except for the blocks 24, 25, 27 and 28 lying in the lower heat flow region of North German Basin. The thermal conductivity values in the region varies from 2.4 to 4.0 Wm-1
