PROJECT

Process-oriented reconstruction of Proterozoic basin evolution in North Australia

Understanding how sedimentary basins formed in the past

 

The basins of northern Australia include several cycles of Proterozoic basin formation including the Calvert, Leichardt and Isan Superbasins, as well as a number of compressional orogenic events.

The evolution of this region is well recorded in the sedimentary basins including the McArthur and Mount Isa regions, with a variety of sedimentary and tectonic environments recorded, including rift, platform and sag basins, and their reactivation and tectonic deformation during compressional orogenesis.

These basins are also well-covered by geophysical data that image the present day structure and characteristics of the basins, including the thicknesses of sedimentary packages, their physical properties and the nature of the crust beneath. Existing “geotransects” include collocated data including seismic reflection lines, gravity, magnetic and magnetotelluric data.

 

This project will seek to reinforce this knowledge by undertaking process-oriented reconstruction of the basins’ structure through time, focusing also on environments for ore deposit formation.

As part of this project the successful PhD applicant will:

  • Devise workflows for process-oriented basin reconstruction with geological and geophysical data
  • Apply these to the Northern Australian region, characterizing the quality of their model results
  • Characterise the formation processes of the basins, as indicated by these geotransects
  • Translate the key processes into element of ore-deposit formation models

 


Research team leader: Dr Alan Aitken 

I am a geophysicist and tectonicist with experience in crustal and lithospheric-scale modelling and geologic interpretation. I have worked extensively in Australia, putting together the pieces of its 3D jigsaw, including defining the vertical and horizontal development of the crust and lithospheric mantle. I also pursue research in other regions of the world and for several applications.

The project is to be co-supervised by an inter-disciplinary team of excellent researchers.
