GRAVITY MODELING A RIFTED CONTINENTAL MARGIN

摘要

Example computer-implemented methods, computer-readable media, and computer systems are described for performing gravity modeling. In some aspects, survey data that includes gravity data of a rifted continental margin is accessed. A value of a geometric parameter is determined, which corresponds to a desired value of a Mohorovicic Discontinuity (Moho) uplift at a specified location of the rifted continental margin. A Moho surface is determined based on a value of Moho uplift at a rift center that is determined based on the value of the geometric parameter. A top basement surface is determined based on a residual gravity data associated with the Moho surface. A crustal model of the rifted continental margin is output. The crustal model includes the Moho surface and the top basement surface of the rifted continental margin.
