Guest Speaker(s): Carmine Wainman

Carmine Wainman is a Visiting Research Fellow at the University of Adelaide. His research focuses on Permian and Jurassic coal-bearing strata in eastern Australia, and collaborations with the International Ocean Discovery Program on the Mesozoic evolution of Australia’s southern margin. He completed a Postdoctoral Fellowship in 2020 and a PhD in 2018 at the same university. Before commencing his PhD, he worked for the RSK Group and Woodside Energy. Carmine also received an MSci (integrated) in Geology from the University of Southampton, United Kingdom in 2012.

Deciphering the Impact of the Late Paleozoic Ice Age and Basin Tectonics on the Prospectivity of the Patchawarra Formation, Cooper Basin

Presented by Carmine Wainman


The Late Carboniferous–Triassic Cooper Basin is Australia’s main onshore petroleum province spanning an area of 153,000 km2. The basin was located in the continental interior of eastern Gondwana at high latitudes (70°S) when the supercontinent Pangea was in its final stage of assembly. From the Late Carboniferous through to the middle Permian – a time known as the late Paleozoic ice age (LPIA) – ice sheets spanned most of southern Australia including the Cooper Basin. Many stratigraphic units in this basin were deposited in-part by glacial processes, but the prevalence and longevity of ice in the environment remain an enigma. Furthermore, the basin’s tectonic evolution during the LPIA and its subsequent impact on paleogeography is poorly understood. To answer these questions, legacy material from the Cooper Basin intersecting the Patchawarra Formation were analysed including cores, well logs and seismic sections. In a first, new high precision U–Pb TIMS age dates were obtained from tuff beds present in the same formation. These new datasets are shedding new light on the LPIA and the evolution of the Cooper Basin. This talk will explore new ideas that the Patchawarra Formation is significantly younger (Kungurian) than initially predicted by palynostratigraphy, and that deposition occurred in a large and shallow lacustrine system with basin-fill derived from glacially fed rivers. Ongoing work interpreting seismic sections are beginning to reveal how the basin’s architecture was constantly evolving, challenging notions that ridges were major features since the formation of the basin and subsequently influenced where sediments were preferentially deposited. These new interpretations have the potential to redefine controls on sediment dispersal patterns, enhance reservoir characterisation within the basin as well as providing new perspectives on depositional environments within continents during icehouse periods.
