Abstract

We provide here an updated geographic and stratigraphic framework of some of the Tertiary basins of central Australia. These have received little attention in the geological literature since the 1960s. This is due in part to the poorly outcropping nature of sequences within these basins, and to strong weathering overprints. As a consequence, this study depends heavily on analyses of drill hole cuttings, supplemented by a few cores. Drilling and reconnaissance geological mapping has shown that the basin sequences have been profoundly altered by weathering, with associated mineralogical and chemical changes. The sedimentary sequence also contains contemporaneous siliceous and calcareous beds, as well as redeposited or recycled sediments including former weathered and/orchemically precipitated rock types. This paper is, therefore, an attempt to unravel the complicated history of development of these basins. It provides a framework for reconstruction of the probable Cainozoic depositional, weathering, climatic and tectonic history of central Australia. Although there are large gaps in knowledge, the data presented has wide implications regionally for the palaeogeographic and tectonic evolution of the Australian Plate. Locally, it is valuable fo the assessment of mineral and groundwater resources.Many of the specific palaeo-environmental interpretations are tentative as, for example, details of the depositional, sedimentary, and stratigraphic details remain to be investigated.
