Rollin, K.E.; O'Brien, C.F.; Tombs, J.M.C.. 1982 Seismic and gravity surveys over the concealed granite ridge at Bosworgy, Cornwall. British Geological Survey, 18pp. (WF/MR/82/049) (Unpublished)
Detailed gravity surveys around the margins of the
Carnmenellis granite have identified several nearsurface
granite ridges, including that drilled at
Bosworgy. In an attempt to define the form of the
granite ridge, two short reflection seismic lines
were shot in 19 75. For various reasons the seismic
results were disappointing and a further detailed
gravity survey was carried out.
This report describes the seismic results and an
interpretation of available gravity data in the
Bosworgy area.
