Geology and tectonic history of the Palaeozoic Hodgkinson and Broken River Provinces, north Queensland

The Hodgkinson and Broken River Provinces form the northern part of the Tasman Orogen. They are separated by a broad belt of Late Palaeozoic igneous rocks, but were probably originally continuous. They are bounded to the west by a system of major faults which separate them from the Georgetown Province. Although largely Precambrian, the Georgetown Province includes probable Silurian-Devonian granitoids, and in the south adjacent to the Broken River Province, Metamorphosed Early Palaeozoic(?) volcanics and sediments of the Greenvale Subprovince. South of the Broken River Province, the Lolworth-Ravenswood Province includes probable Precambrian rocks, Cambro-Ordovician volcanics and sediments, and voluminous Ordovician to Early Devonian granitoids.
