Tombs, J.M.C.. 1977 A study of the space form of the Cornubian granite batholith and its application to detailed gravity surveys in Cornwall. Institute of Geological Sciences, 22pp. (WF/MR/77/011) (Unpublished)
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.
