The Pallamanna Fault is a Palaeozoic feature on the western margin of the Murray Basin near Murray Bridge. Geophysical methods were used to delineate it and to estimate its throw. The results suggest that the fault zone itself is steeply dipping (70o to 80o) to the east but that the associated fault scarp has been eroded, in some places more severly than in others. The throw appears to be of the order of 100m.
