The foreland, Early Permian to Middle Triassic Bowen Basin of eastern Queensland occupies about 160,000 km2 (61,766 mi2), the southern half of which is covered by the Surat Basin (Figure 10). It has a maximum sediment thickness of about 10,000 m (32,808 ft) concentrated in two north-trending dep- ocenters, the Taroom trough to the east and the Denison trough to the west (Elliott, 1989). Deposition in the basin commenced during an Early Permian exten- sional phase, with fluvial and lacustrine sediments and volcanics being deposited in a series of half grabens in the east, while in the west a thick succession of coals and nonmarine clastics were being deposited (Cadman et al., 1998). Following rifting, a thermal subsidence phase extended from the middle Early to Late Permian, during which a basinwide transgression allowed deposition of deltaic and shallow-marine, predominantly clastic sediments as well as extensive coal mea sures. Foreland loading of the basin spread from east to west during the Late Permian, resulting in accelerated subsidence, which allowed the deposition of a very thick succession of Upper Permian marine and fluvial clastics, again with coal and Lower to Middle Triassic fluvial and lacustrine clastics. Sedimentation in the basin was terminated by Middle to Late Triassic contraction (Elliott, 1989).
