MMR surveys for the location of palaeochannels in the Eastern Goldfields, Western Australia

Abstract

The magnetometric resistivity (MMR) method was used to locate palaeodrainage channels in the Eastern Goldfields of Western Australia. Drilling results showed the method does not distinguish between the palaeochannel and porous weathered basement containing saline water. This distinction however was not essential to the success of the program as the weathered basement was generally symmetrical around the channel.
