Abstract
IN this model, which is likely to prove useful to the student and to the practical geologist, the author has adopted an ingenious method of showing the extent and the order of superposition of the geological formations under east and south-east England. The outcrop of each formation is represented on a separate, coloured, map: the Palaeozoic floor forms the base of the model, the successive formation-maps being attached either by their right or left margins. The thicknesses of the beds, as proved in boreholes, are indicated at a number of sites. By these means the unconformities at the base of the Jurassic and the Cretaceous systems, the regression of the Inferior Oolite, and the overlap of the several members of the Cretaceous system, are clearly brought out.
