Results of a gravity survey of the south-west margin of Dartmoor, Devon

By J.M.C. Tombs

Abstract

A gravity survey (station density 4-6 per km2) of the south-western\ud margin of Dartmoor, including the Hemerdon stockwork, was interpreted\ud using previously developed computer techniques, with some refinements,\ud to indicate the depth to buried granite. The results showed (i) that\ud the Hemerdon Ball granite is an isolated block and does not extend to\ud depth, and (ii) that no vertically-continuous shallow granite occurs\ud at any distance from the known outcrop. Various computer-graphics\ud presentations of the data are given
