Abstract

The Ord-Victoria Region, an area of over 70,000 square miles in the north-western portion of Northern Territory and north-eastern portion of Western Australia, is drained by the Ord and Victoria River systems. The geological reconnaissance of the Region was made primarily to provide a geological background for assessment of land utilization by the Land Research and Regional Survey Unit of the ' Commonwealth Scientific and Industrial Research Organization, and secondly to provide information on the stratigraphy and economic geology. This Bulletin presents the results of the geological reconnaissance and includes a geological map at the scale of 16 miles to 1 inch of the Region and two geological maps at a scale of 4 miles to 1 inch of the more important Palaeozoic basins in the Region. Rock units of Precambrian, Cambrian, Ordovician, Devonian, Carboniferous, Permian, Jurassic, Cretaceous, Tertiary, and recent ages were mapped and described, and fossil collections were made from more than 50 localities. The discovery of Permian volcanics-the only confirmed post-Cambrian volcanics in Northern Territory-is recorded. Mineral production for the Kimberley Field is listed, and occurrences of gold, silver, lead, tin, copper, ochre, and bauxite are discussed. Aerial scintillometer surveys are recommended to determine if uranium deposits occur in the Halls Creek metamorphics. A study of hydrology was made and the underground water conditions in different areas are discussed. Petroleum prospects in the different basins are considered' and it is thought that the possibility of finding petroleum in commercial quantities in the Region is slight.
