Abstract:

During this work, the regional gravity data acquired earlier were used and in order to investigate the relations between geology - tectonics and elevation, isostatic map of Turkey, free air anomaly map and Bouguer anomaly maps were obtained, and comparisons with respect to elevations were carried out. For the thickness of the earth crust T 0 32 - 0.08g relation was used. The best relation was obtained from Bouguer anomaly with +0.65 coefficient; the relation function was obtained as Y = - 72E + 7.77. Thickness of the crust of Turkey is estimated to be 31.4 km where it is the shallowest and 50 km where it is deepest.
