A geo/archaeological watching brief and deposit model was undertaken for the site of the Ratcliffe-on-Soar Power Station, Nottinghamshire. This document summarises the stratigraphic sequence of geoarchaeological remains and discusses the results in relation to their archaeological and palaeoenvironmental potential. The geo/archaeological monitoring exercise comprised the monitoring of 20 geotechnical boreholes to a maximum depth of 30 m BGL, and the monitoring of 29 geotechnical trial pits to a maximum depth of 4 m bgl. No core samples were available to be retained for geoarchaeological purposes. Geoarchaeological and geotechnical deposit data can be used to identify areas of archaeological potential by characterising the probable nature and depth of sub-surface deposits. The only arcaheological feature recorded was a small northeast-southwest aligned gully cut into the underlying Mercia Mudstone, which contained no finds, and was capped by the sub soil. It may be of prehistoric to modern date but provides little potential for further investigation. The deposit sequence recorded across the site included tertiary bedrock of Mercia Mudstone Formation (encountered between approximately 24.5 and 44.0 m OD), superficial units of Pleistocene head, Hemington and Syston Member Gravels and alluvial silts, and Holocene clay / weathered bedrock. The nature of the Holocene clay / weathered bedrock is at present undetermined in the available records, though it may represent alluvium. Sealing the site were topsoil and made ground, the latter with a thickness of up to 11.6 m. Subsoil was present in only four of the test pits, followed by topsoil in all of the trenches. Archaeological remains were present in test pits four and ten, with the rest of the test pits being negative. The archaeological remains consisted of an undated pit, and undated northeast-southwest aligned gully.
