Repeated failure: long-lived faults in the eastern Musgrave Province.
Aeromagnetic images of the Musgrave Province are characterised by a series of laterally continuous, approximately east-west-striking, magnetically low lineaments, which have been interpreted as faults. These structures have been divided into two main...-

The link is in the geochemistry: how we know a metasomatised mantle underlies the mineral systems of the Gawler Craton.
A coherent and related system of Mesoproterozoic magmatism, hydrothermal alteration and deformation extends from the western Gawler Craton to eastern Curnamona Province. This system produced the Olympic Dam iron oxide – copper–gold (IOCG) orebody and...-

Timing of advanced argillic alteration at Nankivel Hill, SE of Paris silver deposit, northern Eyre Peninsula.
Igneous activity across the Gawler Craton during the Mesoproterozoic (c. 1595–1575 Ma) resulted in intense hydrothermal activity and formation of iron oxide – copper–gold (IOCG) deposits along the eastern margin of the craton. Other mineralisation has...-

The final event in the long evolution of the Gawler Craton: new constraints on 1450 Ma metamorphism and magmatism.
Potential field data across the northern Gawler Craton reveal structural fabrics and a number of large plutonic bodies that suggest the region has a complex tectono-metamorphic and magmatic evolution. Existing geochronological studies confirm this...-
