Finding Orebodies for the Year 2001: The Metamorphosis in Geophysics

Clearly visible in geophysics is a trend away from simply finding and drilling anomalies obtained with off-the-shelf equipment, condes- cendingly sold by travelling salesmen. Instead, technical tools are becoming available which allow us to choose or design equipment and sur- vey procedures for the specific problem at hand. The advent of micro- and smaller computers enable us to collect more and better measure- ments and to rapidly process them so as to emphasize the features which are being sought. These new capabilities have important consequ- ences both to the extent to which geophysical tools will be applied in the industry, and to the skills which will be demanded of those using them. Because of its uniquely difficult exploration problems, Australia must expect to amplify its new prominence in the development of mining geophysical technology.
