Forearc basin dynamics and sedimentation controls, Tamworth belt, eastern Australia

The eastern margin of the Australian continent was the site of convergent plate interaction for much of the Palaeozoic Era. The Tamworth Terrane, a forearc complex resulting from this interaction, occurs in the northeastern corner of New South Wales. This forearc basin, now preserved as a complex erosional and tectonic remnant in the Tamworth belt and Hastings block, originally formed a relatively linear belt before terrane dispersal resulting from Permian orogenesis. Tectonic-subsidence curves derived from thirteen well-exposed sections show that subsidence began abruptly, continued for approximately 50 Ma, and then ceased just as abruptly. Total tectonic subsidence was 4- 6 km at either end of the basin, and 2- 3 km in the intervening areas of the southern Tamworth belt. Depositional patterns were controlled largely by sediment supply and subsidence; the preserved sedimentary rocks form a large-scale upward-shallowing succession. In detail, the effects of eustatic sea level change are also apparent, particularly around the basin margins and in the shallower water associations. The continuous interaction among these three major variables produced a basin that changed in morphology both spatially and temporally.
