The geology of the Pang-Lambourn catchment, Berkshire

This report describes the geology of most of the Berkshire Downs. Together with a complementary geological map at 1:50 000 scale, it was produced as part of the infrastructural information provided for the LOCAR (Lowland Catchment Research) Project, under the NERC Thematic Programme. The introduction describes the topographic and geological setting of the project area. Subsequent chapters respectively describe the solid (or bedrock) geology, the superficial (or drift) geology, and the geological structure. Most of the area is underlain by the Upper Cretaceous Chalk Group. The Lower Cretaceous Upper Greensand and Gault, and a small area of the Jurassic Kimmeridge Clay, occur in the north. The Palaeogene Lambeth Group, London Clay Formation and Bagshot Formation occur in the south. Superficial deposits are landslip, head, clay-with-flints, sand in clay-with-flints, peat, alluvium, river terrace deposits. Areas of worked ground, made ground, infilled ground and landscaped ground have also been delineated. Figures and tables appear at the end of the report.
