Abstract

AbstractA large part of County Durham is underlain by carbonate rocks of Permian age, principally Magnesian Limestone. In recent years problems have been encountered in constructing on the Permian carbonates, due to dissolution followed by subsidence and/or sink hole formation.Features believed to be triggers for dissolution of limestone have been mapped and a weighted factor hazard map has been created. The map is based on an extensive review of existing site investigation data including a study of aerial photographs. Records of dissolution features noted by the County Council engineers have been incorporated into the hazard map. The map is intended as a guide for County Council Engineers who are planning site investigations within the area. The preparation of the map and its limitations are discussed.
