To extend the line-integral method for calculating gravity anomalies of irregular two-dimensional geological bodies whose density contrast varies linearly or exponentially with depth.
Approximated two-dimensional cross-sections of arbitrary shape as N-sided polygons.
Calculated individual line integrals from vertex coordinates of each polygon side and summed them to obtain total gravity anomalies.
Formulated mathematical solutions for both linear and exponential density-depth variations and applied the formulation to the San Jacinto Graben in California.
Demonstrated that line-integral summation across polygonal boundaries accurately determines gravity anomalies for bodies with non-constant vertical density contrasts.
Successfully modeled the subsurface structural geometry of the San Jacinto Graben using an exponential increase in sediment density with depth.
