Chinnor, Chalk and Cement Mr. W. Benton's Cement and Lime Works opened in Chinnor in 1908, but cement making on a truly industrial scale did not begin until 1919. Output of cement from Chinnor peaked at about 5600 tonnes per week in the 1990s. Up to 120 people were employed at any one time. The cement works closed in 1999 and there are plans for the re-development of the site, using the flat areas for housing but also with opportunities for recreation and conservation in the water filled quarries The scale of chalk extraction for cement making can be seen from a short walk along the Ridgeway National Trail. The Ridgeway runs on a high causeway between the large quarries, giving views of the pits through the boundary fences. (Do not cross over or through the fences). Geology One of the chalk quarries has been protected as a geological Site of Special Scientific Interest as it has particularly good exposures of both the Lower Chalk and Middle Chalk geological layers. Both layers have given upimportant fossil ammonites.
