Paper Abstract

Analysis of the Geoscan Mk II scanner imagery obtained over the past twelve months in Australia and in the USA has shown that this advanced system can effect direct mineral identification (DM1) with only a minimum of processing and in an operational commercial mode of use. This paper attempts to show some of these results with imagery flown over goldmineralizaon (Leonora W. Australia) porphyry-copper mineralization and associated higher-level advanced argiffic alteration (Yerington NV--Ann Mason and Buckskin Ra. ) and a copper-gold skarn nearby (Ludwig NV). In all cases simple banddifferencing is all the processing that is required and this can be effected minutes after landing from a flight using a proprietary image-display system (GIPSy) which accepts the optical disks directly.
