Abstract

Investigations described from three Victorian damsites indicate that weathering of Ordovician bedrock is increased where it is overlain by basalt, even though the basalt is little weathered. Sub-basaltic weathering may account for the fact that weathered rock beneath a Jurassic lava flow gives a weathering remagnetization age of Mid-Cainozoic, consistent with palaeomagnetically determined ages of lateritization from elsewhere in Australia.
