Wolstonian

views updated May 08 2018

Wolstonian The glaciation which followed the Hoxnian Interglacial; a pale, chalky till (the Gipping Till) occurs in East Anglia, England, and the stone orientation and the included erratics suggest a movement from the north. The general stratigraphy needs clarification since it is not certain that the till rests on Hoxnian deposits and there are a number of morainic deposits attributed to this glacial which occur in Norfolk. During this ice advance a large lake, Lake Harrison, was ponded up in the Midlands. The Wolstonian perhaps correlates with the Saalian.
