A simple relation exists between the depth to basement and gravity or pseudo-gravity fields. Based on this relation, a method to recover the density (or magnetization) contrast function and the basement morphology under sedimentary basins is developed. Use of this method is possible when several depth constraints are available, as given by boreholes perforating the basement or other geophysical data interpretations indicating the depth to basement at some locations. A nice feature of the method is its computational efficiency, as it involves no matrix inversion nor multiplication. The new method has been successfully applied to complex basement model and to a real data set.

Abstract
A simple relation exists between the depth to basement and gravity or pseudo-gravity fields. Based on this relation, a method to recover the density (or magnetization) contrast function and the basement morphology under sedimentary basins is developed. Use of this method is possible when several depth constraints are available, as given by boreholes perforating the basement or other geophysical data interpretations indicating the depth to basement at some locations. A nice feature of the method is its computational efficiency, as it involves no matrix inversion nor multiplication. The new method has been successfully applied to complex basement model and to a real data set.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
