The Geology of the Isle of Purbeck and Weymouth

Abstract

ANY ONE travelling from London to the South Coast may see how the gentle southerly inclination of the chalk, which has carried it under the Tertiary beds, changes on the south side of the trough, bringing the chalk up again with a steeper slope, but now with a northerly dip; how it then folds over the axis of the Wealden anticlinal, only to fall to the south more rapidly than it did before, and pass under the waters of the Channel. If we make our traverse further west, there, in consequence of the strike of the rocks being oblique to the trend of the coast, we find still more southerly folds brought into view, and the chalk, after passing rapidly under the Tertiary beds of the Hampshire basin, reappearing in the Isle of Wight, with the strata vertical or even thrown over beyond the vertical. Along this line of disturbance older and older Mesozoic rocks turn up in the anticlinal folds.
