That frustration is even more acute because, as Ken has pointed out, the issue has been around for decades. In 1997, for example, in a CRC AMET workshop on Future trends and directions in mineral exploration geophysics (see Preview 66) several contributors expressed the view that the rapid advances in geophysical techniques would not benefit exploration until geologists developed a better understanding of those techniques, and learnt how to work with the data being generated.The ASEG is currently being proactive about bridging the gap between geologists and geophysicists.
