The Bonaparte Gulf Basin is a north-pitching syncline of Phanerozoic sediments, which are bounded to the south by Precambrian rocks and extend northward beneath the Timor Sea (Fig. 1). The landward part of the basin has been fragmented by faults, uplift, and erosion into a main outcrop area and three outliers. The eastern edge of the original depositional basin corresponds approximately with the present eastern margin, but the original extent to the south and west is unknown. Within the main outcrop is a Precambrian inlier, the Pincombe Inlier, which influenced deposition during the Upper Devonian and Lower Carboniferous. The main outcrop (Fig. 2) comprises Lower Cambrian volcanics, and Cambrian, Lower Ordovician, Upper Devonian, Carboniferous, Permian, Lower Triassic, and Lower Cretaceous sediments. The outliers contain only the lower part of this sequence, up to and including the lower part of the Upper Devonian.

This Bulletin presents the results of systematic geological mapping in north Queensland by joint field parties of the Bureau of Mineral Resources and the Geological Survey of Queensland, during the period 1958 to 1963. The area investigated is more than 36,000 square miles, and extends from Princess Charlotte Bay in the north to the township of Ingham in the south, and from 142°30'E. to the shores of the South Pacific Ocean. It is the site of a Palaeozoic geosyncline the Hodgkinson Basin and includes part of the western Precambrian borderland, which is separated from the geosyncline by the Palmerville Fault, a large fundamental structure.
