Seismic and gravity surveys over the concealed granite ridge at Bosworgy, Cornwall

By K.E. Rollin, C.F. O'Brien and J.M.C. Tombs

Abstract

Detailed gravity surveys around the margins of the\ud Carnmenellis granite have identified several nearsurface\ud granite ridges, including that drilled at\ud Bosworgy. In an attempt to define the form of the\ud granite ridge, two short reflection seismic lines\ud were shot in 19 75. For various reasons the seismic\ud results were disappointing and a further detailed\ud gravity survey was carried out.\ud This report describes the seismic results and an\ud interpretation of available gravity data in the\ud Bosworgy area
