Regional-residual gravity anomaly separation using the minimum- curvature technique
One of the most difficult problems in gravity interpretation is the separation of regional and residual gravity anomalies from the Bouguer gravity anomaly. This study discusses the application of the minimum-curvature method to determine the regional and residual gravity anomalies. The technique is applied to gravity data within and surrounding the Richmond Basin in central Virginia. The resulting minimum-curvature regional and residual gravity anomalies are compared to those obtained by the polynomial trend surface method.
