Thesis: Multi-scale Mineral System Prospectivity Analysis of the east Kimberley; Insights from Geophysical and Numerical Geodynamic Modelling

The overarching aim of this research is produce gold and nickel prospectivity maps in the east Kimberley (Halls Creek Orogen-“HCO”) by applying a range of geological, geochronological, geophysical, remote sensing and numerical techniques to understand the mineral system components that are required to form and preserve gold and nickel deposits on a variety of scales. For this work I will:

- Review the lithospheric architecture and geological evolution of terrain

- Test tectonic models and geodynamic triggers for the East Kimberley by application of numerical modelling techniques.

- Translate 4D controls on mineralisation into a mineral system framework with an emphasis on metal and fluid source, active pathways, physical and chemical deposition drivers, threshold barriers, and preservation factors.

- Produce gold and nickel prospectivity maps in GIS environment by define targeting criteria on a variety of scales ranging from regional to deposit scales.

Why my research is important

For the first time, this PhD thesis will focus on a multi-scale and multi-dimensional prospectivity analysis of the east Kimberley region in the north of Western Australia based on mineral system approach (MSA) by applying geodynamic modelling. The main objective of the project is to understand the lithospheric architecture, geodynamic triggers through time, and delineate mineral system components and prospective sites of gold and nickel in the region on a scales ranging from regional to camp to deposit scales. Such a multiscale analysis with applying scale dependent targeting criteria and implications of geodynamic modelling, has the potential to produce a new model for prospectivity analysis.
