f Geophysical Exploration for Paleochannels in Western Australia

Palaeochannels are a major source of groundwater to many of the mines and associated mining towns in Western Australia. Formed to depths of up 130 metres they occur over a variety of Archean and Proterozoic rocks including granitoids, mafics, ultramafics and sediments. They have been explored for both groundwater and gold with the target formation for both being the medium to course sands formed as a basal unit within the palaeochannel.
