Two-dimensional interpretation of gravity anomalies over sedimentary basins with an exponential decreases of density contrast with depth

摘要

The decrease of density contrast with depth in sedimentary basins is approximated by an exponential function. The anomaly equation, in frequency domain, of a prismatic model with an exponential density function is derived. The method has been extended to derive the Fourier transforms of the gravity anomalies of the sedimentry basin, wherein the basin is viewed as vertical prisms placed in juxtaposition.
