The Granites-Tanami 1:500,000 regolith-landform map illustrates the distribution of regolith materials and the landforms on which they occur, described using the RTMAP scheme developed by Geoscience Australia

The map of iron oxide copper-gold (IOCG) potential of the Gawler Craton, South Australia, shows the spatial distribution of key 'essential ingredients' of IOCG ore-forming systems. These 'ingredients' include: (a) rock units of the Gawler Range-Hiltaba Volcano-Plutonic Association, subdivided by supersuite; (b) faults/shear zones subdivided by interpreted age of youngest significant movement; (c) copper geochemistry (>200ppm), from drill holes intersecting crystalline basement (Mesoproterozoic and older); (d) hydrothermal alteration assemblages and zones, based on drill hole logging, potential-field interpretation, and inversion modelling of potential-field data; and (e) host sequence units considered important in localising IOCG alteration and mineralisation. Also shown are Nd isotopic data and the mineral isotopic ages of late Palaeoproterozoic to early Mesoproterozoic magmatism and hydrothermal minerals. Areas with the greatest number of 'essential ingredients' are considered to have the maximum potential for IOCG mineralisation. IOCG potential of the Gawler Craton is shown as domains with ranks from 1 to 4, with 1 being the highest rank. Notes detailing the sources of data and methods used in constructing the map are provided in a separate file available on the Geoscience Australia website.

The Olympic Cu-Au Province, of the eastern Gawler Craton, lies beneath the sedimentary sequences of the Stuart Shelf. Rocks of the basement are Late Archaean metamorphics, and the Proterozoic Donington Suite, Hutchison Group, Wallaroo Group, Hiltaba Suite granitoids and mafic intrusives, and the Gawler Range Volcanics. Except for parts of the Gawler Range Volcanics, none of the basement crops out and is covered by sequences exceeding 3 km thickness, in places. Interpretation of units and structures was via gravity and airborne magnetic data. Some geological calibration was done by checking exploration drill logs or by examining the core. When core was examined, petrophysical properties were measured and used to constrain the interpretation.

The Curnamona 1:500,000 regolith-landform map illustrates the distribution of regolith materials and the landforms on which they occur, described using the RTMAP scheme developed by Geoscience Australia

Structures and distribution of Archaean greenstones and granitoids are simplified from the 1:500 000 solid geology map by Liu et al. (2000). Distribution of mineral deposits are compiled from GSWA's mindex database as of 30 June 2000 and AGSO's ozmin database as of Nov. 2000.
