Excerpt from Memoirs of the Geological Survey: England and Wales, the Geology of the Country Around Fakenham, Wells, and Holt (Explanation of Quarter-Sheets 68 N. W. And S. W.) The part of Norfolk described in the following Memoir; is contained in the two Quarter-Sheets 68 N.W. and S.W. It presents no remarkable geological features, being essentially an agricultural district, which owes its fertility to the marls and loams that cover the greater part of its surface. So widespread are these superficial deposits that the underlying platform of Chalk comes to the surface only here and there. One edition of the maps - that on which the drifts are coloured - is therefore sufficient to show the geology, since it is quite impossible to trace any lines under these overlying accumulations, or to be certain how far Pliocene or other deposits may not occasionally intervene between them and the Chalk. Owing to the difficulty in correlating the Glacial marls and clays, it has been thought advisable to colour the Boulder Clay in one tint, and to express by one colour also all the Glacial Sands and Gravels, although more than one sub-division may in each case be thus united. These deposits are mainly a prolongation of the Contorted Drifts of Cromer, like which, though their grouping and structure seem simple on the map, they are subject to considerable variation and to local, and doubtless glacial, disturbance. Much detail necessarily of an uninteresting nature is given in this Memoir; but it is here put on record, as it may prove of value in regard to local questions of drainage, water-supply, lime-burning, brick-making, and the supply of road-metal.
