Abstract

The AA. used an archive of borehole logs from the British Geological Survey to collect information on the spatial structure of weathering that extends from the surface to competent bedrock across the Triassic Sherwood Sandstone Group outcrop, in the East Midlands, UK. The weathering profile of the sandstone consisted of soil overlying a transition zone of compacted and weakly cemented weathered sandstone saprolite over bedrock. Topographic analysis using a NEXTMAP 5 m x 5 m digital elevation model (DEM) revealed no significant relationships between slope properties and soil or soil and saprolite (S&S) thickness. A weak, but statistically significant correlation was found between the thickness of the soil and S&S. The AA. hypothesize and provide evidence that the greater weathering thickness is related to the occurrence of increased faulting in this part of the study region, allowing increased access to meteoric waters
