Abstract
Summary: The area consists of Kimeridgian, Portlandian, Wealden, Aptian( ?) and Albian rocks (Kimeridge Clay to Gault) with terrace gravels of the River Thame and its tributaries. The Jurassic and Wealden rocks are folded and faulted along northwest axes. After the movements had come to rest the resulting structures were planed off and red sands, attributed to the Upper Aptian or Lower Albian (Lower Greensand), were deposited unconformably. The sands are in turn overlapped by the Gault, which has been traced overstepping unconformably across an eroded anticline in the Jurassic rocks. Finally, the Gault itself is faulted along the same north-west lines as the older rocks, but with downthrows in the opposite sense.
