PROJECT

Thermal structure and evolution of Proterozoic sedimentary basins in Northern Australia – a numerical study

Modelling how sedimentary basins formed in the past

 

This PhD project is part of multi-disciplinary ARC linkage project that involves UWA, University of Sydney and Monash University, as well as industry partners. As a result the student will be working with experts across the three institutions as well as post-docs and other post-graduate students. The project will involve a two-month visit to Sydney University to work with Prof. Patrice Rey, and the team there.

In this project the student will use well-tested numerical geodynamic code – Underworld2 (2 and 3D) or I2VIS (2 and 3D). These are fully coupled thermomechanical code able to simulate elastic-plastic-viscous deformation (including power-law creep), the weakening effects of temperature, strain and melt, and the effect of melt on the geotherm through latent heat, as well as the effect of temperature on density (and buoyancy) through thermal expansivity.

 

Underworld2 has recently been coupled with Badlands – a state of the art landscape evolution code, that simulates surface changes at various space and time scales. Badlands is capable of simulating hillslope processes (diffusion), fluvial erosion (stream power law), sediment transport (sediment flux conservation) and deposition.

As part of this project the successful PhD applicant will:

  • Establish parameter studies for numerical models, and interpret numerical models
  • Analyze numerical models against geological/geophysical/geochemical data from Northern Australia
  • Write simple routines in Python, Matlab or C to process the results of numerical models.

 


Research team leader: Dr Weronika Gorczyk 

I am a geodynamicist with experience in crustal and lithospheric scale modelling of variable tectonic settings. I have applied numerical modelling to verity of tectonic setting, including subductions and intraplate deformation. I have applied numerical modelling to understand different parts of the world in space and time.

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