Geology of Cambridgeshire

The geology of Cambridgeshire in eastern England largely consists of unconsolidated Quaternary sediments such as marine and estuarine alluvium and peat overlying deeply buried Jurassic and Cretaceous age sedimentary rocks.

This article describes the geology of the ceremonial county of Cambridgeshire. It thus includes the present City of Peterborough and the historic county of Huntingdonshire which was brought into the county in 1974.
