AUSTRALIA/Proterozoic 217 Table Continued bimodal volcanics and interlayered metasedimentary rocks of the Myola Volcanics and the Broadview Schist, and the Peake Metamorphics were deposited on the Gawler Craton $1790 Ma, contemporaneous with syntectonic granitic rocks of the Lincoln Complex Further volcanic rocks and metasedimentary rocks were deposited between $1765 and $1735 Ma (McGregor Volcanics, Moonabie Formation, and Wallaroo Group) The third phase of the orogeny took place between 1745 and 1690 Ma and involved deformation, medium-grade metamorphism, and further granite intrusion (Figure 4) Following accretion to the North Australian Craton, the site of subduction may have moved to
