A procedure to select and reduce satellite magnetic anomaly data in high southern latitudes is described, and a map of Antarctica, constructed using this procedure, is shown. The map is qualitatively analyzed for error and geologic significance. Correlations are noted between magnetic anomalies and mountain ranges, subglacial basins, tectonic provinces, regional gravity anomalies, a hypothetical continental rift feature, oceanic basins, and oceanic rises. Overall, the correlation between the magnetic anomaly patterns and known geological features is good.
