Abstract

"The name Whitchurch sands is proposed for patches of ferruginous strata scattered for 75 miles along the western edge of the Cretaceous from Stewkley, Buckinghamshire, to the Vale of Pewsey, in Wiltshire. They are interpreted as the vestiges of a marine- brackish formation of middle Purbeck age indicating the transgressive front of an advancing sea thought to have come from the north and which left its mark farther south in the Cinder bed of Dorset. In the past they have been regarded as lower Greensand, Wealden, or Portland sand."
