Gravity and reduced-to-pole total magnetic intensity grids over the northern Gawler Craton have been vectorised, generating polygon datasets representing regions of locally anomalous gravity and magnetic intensity. Statistics from potential field grids were embedded into each polygon which enabled calculation of anomaly magnitude. Known IOCG-type deposits were found to be consistently associated with coincident to semicoincident magnetic and gravity anomalies, with residual Bouguer gravity anomaly magnitudes greater than 4.8 milliGals (mGal). Known iron ore deposits were found to be associated with residual TMI anomaly magnitudes greater than 3800 nanoTesla (nT). Analysis of spatial clustering and the identification of outliers using Anselin Local Morans I (ESRI, 2013) has resulted in the delineation of geographic regions across the study area that exhibit either high magnitude clusters or high magnitude outliers, which correspond to known regional geological and metamorphic domains. In the eastern Gawler Craton, high magnitude spatial outliers are of particular interest, as they include a high proportion of currently identified iron oxide – copper–gold (IOCG) deposits and mineral occurrences. Moreover, these spatial outliers appear to lie within the Olympic Domain, possible redefining the extent of the domain. Results from this study suggest additional untested spatially coincident magnetic and gravity anomalies that warrant further investigation.
