摘要：

Resistivity sounding is successfully used to determine depth to Cretaceous Chalk bedrock at two contrasting sites. The trend of a buried cliff-line is highlighted at Boxgrove, where the ancient cliff is modelled at around 40 m O.D. with a seaward Chalk platform between 35 m and 40 m O.D.. At Barnham, the configuration of a Middle Pleistocene glacial river channel is constrained and resistivity variations in response to lithological changes noted. Solid Cretaceous Chalk reveals a resistivity value of 105 Omega m, rising to 130-142 Omega m at weathered horizons.
