In South Australia the Gawler Province displays a history of early Proterozoic orogenic evolution and transitional tectonism leading to deposition of the Gawler Range Volcanics (ca 1500 Ma) on a relatively stable platform. A fragmentary record of platform deposition on the resulting Gawler Craton provides a link with the Adelaide Geosyncline (mainly <1000 Ma) which was folded to form the Delamerian Foldbelt in the Delamerian Orogeny (ca 500 Ma). In northern South Australia, the time interval between 1500 Ma and 1000 Ma was a period of intense orogenic reactivation of the early Proterozoic orogenic complexes in the Musgrave domain of the Musgrave-Fraser Province. The evolution of the Musgrave domain should be compared with the Fraser and Albany domains and the southern part of the Arunta domain.
