UAiPhD Project 2020-2024: Exploring the Paleozoic Warburton-Amadeus Depositional System with Novel Isotope Techniques: New Constraints on Chronostratigraphy and Thermal History of the Basins

One of the largest but poorly explored depositional systems in Australia comprises the Paleozoic carbonate/siliciclastic systems of the Amadeus and Warburton Basins, located in central and South Australia, respectively. Sedimentary archives of these presumably inter-connected marine basins thus provides (i) a unique record of the Cambrian and early Paleozoic geological and biological evolution, and also (ii) potentially economic hydrocarbon and metal resources.

The specific aims of this UAiPhD project are:

  • Create an isotope based 'thermo-chronological model' for the basins using results from (i) clumped isotopes in carbonates, and (ii) Rb/Sr and K/Ca dating of glauconites and illites
  • Generate a basin-wide Cambrian carbon-isotope chemostratigraphy framework for the Warburton basin, covering the Thargomindah Shelf up to Birdsville Track Ridge
  • Link the acquired isotope data from the Amadeus-Warburton system to a local biostratigraphy record and global marine isotope records with implications for the earth system evolution studies and paleo-biology.

Overall, this PhD project aims to develop and apply novel isotope techniques - in situ RbSr dating of illite/glauconite, and clumped isotope thermometry of carbonates - to better constrain (i) the absolute ages of sedimentation and organic carbon deposition in the Warburton-Amadeus basins, and the (ii) thermal and burial histories of Palaeozoic strata in these basins that in turn controlled local hydrocarbon generation. These novel isotope techniques will be complemented by more established exploration tools available at CSIRO in Perth (K-Ar dating) and/or SANTOS company based in Adelaide (biostratigraphy, geophysics).

This UAiPhD project will also provide an opportunity to work on specific industry related problems, with the SANTOS exploration company as a partner, while being supported by academic supervisors at the Uni Adelaide and the Metal Isotope Group (MIG) (https://sciences.adelaide.edu.au/physical-sciences/metal-isotope-group), as well as an industry supervisor at SANTOS (www.santos.com) for the duration of this 4-year PhD program. This UAiPhD project and its 6-month industry placement component will take place in Adelaide, South Australia, but the student will be also required to travel to Perth (CSIRO) and perform a fieldwork and sample collection in remote areas of central Australia.
