  • The Cape York 1:1,500,000 regolith map illustrates the distribution of regolith materials described using the RTMAP scheme developed by Geoscience Australia

  • This product covers interpretation of the full geophysical extent of the Yilgarn Craton, and also most of the Albany-Fraser province to the south-southeast. The interpretation covers the Meekatharra (SG50), Wiluna (SG51), Perth (SH50), Kalgoorlie (SH51), Albany (SHI50), and Esperance (SI51) 1:1M sheets. The data set predominantly addresses the Archaean rocks of the Yilgarn Craton but includes interpretation of the adjacent, abutting or onlapping Proterozoic rocks such as the Northampton Block, Yerida, Bryah, Padbury and Earaheedy groups, Albany-Fraser Province, Stirling and Mt Barren Beds, and Phanerozoic Perth and Officer Basins. The aeromagnetic interpretation provides most information on the distribution of the Archaean rocks as these rocks are generally moderately to highly magnetised with reasonable variation of magnetisation. Adjacent Perth Basin sediments are poorly magnetised and spatially associated magnetic anomalies are attributed to underlying Proterozoic rocks. The Archaean rocks are subdivided into undivided gneiss-migmatite-granite (Agmg), banded gneiss (Agn), sinuous gneiss (Anu), greenstone (Aa), and granite plutons (Ag). Where important relative differences in magnetisation are mapped, the geophysical map units include the suffixes _h (high), _m (medium), _l (low) and _r (remanent) for the level of magnetisation. Dykes, faults, and unassigned small intrusives are also mapped. Large Archaean domains equivalent to geologically defined Provinces are also defined including Narryer, Murchison, Toodyay- Lake Grace, Southwest, Southern Cross, Yeelirrie, Lake Johnston and Eastern Goldfields domains.

  • The early to mid Archaean Pilbara Craton is one of the best exposed and least dismembered granite/greenstone terrane in the world, and is an excellent study area of early earth evolution. The Pilbara Craton records successive greenstone sequences (>3515 Ma to 2950 Ma) deposited on a gneissic (tonalite-trondhjemitegranite) crust (<3650 Ma) in a series of synclinal troughs that envelope large (> 100 km diameter) composite ovoid granitoid complexes (3650 Ma to 2850 Ma). The mineral potential of the Pilbara Craton has been generally down played by industry and the area has thus not received the intense exploration industry focus seen in the Yilgarn Craton (especially the Neo-Archaean Eastern Goldfields) to the south. The Pilbara Craton differs fundamentally from many other granite/greenstone terranes in terms of its tectonic evolution and metallogenesis.
