Geology & landscape
Geological Period: Jurassic, Quaternary
Landscape processes: Glacial
Description
Area,1.6 hectares Description A key Quaternary site of considerable stratigraphic importance, both regionally and nationally. Subsurface investigations have revealed a sequence of chalky till almost certainly the equivalent of the Upper Oadby Till, lake clays, peats and silts in a steep sided basin cut in the Jurassic bedrock. Pollen spectra of both Ipswichian Interglacial and Devensian Glacial Stages are present and the stratigraphy provides a continuous sequence spanning pollen zones Ip IIb to e De. Characteristically high levels of Carpinus pollen occur in zone Ip II I. The site is particularly important in providing the longest Ipswichian stage sequence recorded in Britain to date. It has also yielded notable new palaeobotanical records for the Ipswichian Interglacial. Furthermore, the stratigraphy of the site and its position between the Midlands and East Anglia are significant in the context of the controversy over dating and establishing the stratigraphic relationships of the chalky tills of both regions.
