Extensive thrust-stacking of the succession (Archibald, 1987) was followed by middle-amphibolite-facies metamorphism and the intrusion of syn-kinematic domal granitoids, such as the Widgiemooltha Monzogranite (Binns et al., 1976; Archibald et al., 1978; McQueen, 1981) during peak metamorphism and cleavage formation at about 2,660 Ma (Hill and Compston, 1986).
Geologically, these faults were initiated as thrust faults along the Main Mantle Thrust (MMT), however, due to rapid Neogene uplift of the basement rocks, the MMT has been reactivated as dip- and strike-slip faults accommodating domal uplift of the syntaxis.
