Abstract/Summary

A three-dimensional computer model of the Cornubian granite batholith, defined by polygonal contours, was created so that its calculated gravity field matched the observed Bouguer Anomaly field, both onshore and offshore. The model was used to define a background (= “regional”) field in three areas where detailed gravity surveys had been undertaken in the search for shallow granite. From the residual field maps of de@h to granite were produced by an iterative technique. Geological interpretations of the batholith model and of the depth maps are included.
