In the light of new data of geophysical investigations, gravity model of the earth crust along the profile, crossing the South Caspian Basin (SCB) north-southwards has been considered in this paper. Gravity model of a deep structure of the earth crust and the upper mantle along the investigated profile has been created by trial-and-error procedure. To compensate the observed gravity field there has been conducted interpretation of density discontinuities of the upper boundary of the oceanic crust and Moho discontinuity. In the model in the conjugation zones of the oceanic and continental crust, in the oceanic crust one can observe local bending which is likely to be linked with the process of subduction. In the middle of the profile the oceanic crust concave up.
