Abstract

Permian sediments are preserved in a number of Australian basins. The Permian evolution of the basins on the western and northern margins of Australia was controlled by extensional processes that have been related to the rifting of some continental fragments from the margin of Gondwana. The development of many of the Permian basins in central and eastern Australia can also be related to stresses generated along the margins of the continent. The Sydney-Gunnedah-Bowen Basin was initiated in the Early Permian as a result of back-arc extension or transtension. The basin was later affected by periods of compressional or transpressional tectonism which culminated in the Middle Triassic. A change in relative plate motions on the eastern margin of Australia in the latest Carboniferous or Early Permian resulted in the formation of a large double orocline in the New England Orogen and the migration eastwards of the southern portion of the magmatic arc. The New England Province was therefore in a back-arc extensional setting throughout most of the Permian, whereas the Yarrol Province to the north remained in anarc and fore-arc setting. Convergent margin volcanism ceased in eastern Australia by the mid-Permian.
