The gravitational and magnetic exploration of parts of the Mesozoic-covered areas of south-central England

Summary Gravity and magnetic anomaly maps for large areas of southern England are presented, and their geological implications are discussed. The geophysical results are interpreted in terms of the probable composition and structure of the hidden Palaeozoic floor, with particular reference to the possibility of the existence of appreciable thicknesses of Upper Carboniferous rocks in some parts of the area.
