Abstract
The 2 deg averaged data set was analyzed and filtered to produce a magnetic anomaly map of the Australian continental region. The map was overlain on a tectonic map of Australia and correlations were made. A data set was selected that is dominated by relatively low elevation profiles with small changes of elevation within the Australian area in an effort to maximize the crustal anomaly field signal and reduce the effect of variation in satellite elevation. Support systems, both hardware and software are described and best-worst case errors encountered during processing of MAGSAT investigator tapes are summarized. The Broken Ridge anomaly was studied for model development purposes.
