Thesis: Defining Mineral Systems footprints in the Edmund Basin of Capricorn Orogen using proximal and remote sensing reflectance spectra (VNIR, SWIR)

The aim of this project is to discover how mineral spectra can be utilised in identifying mineralisation signatures through the regolith cover. The scope is to identify the mineral assemblages that are characteristic for four schematic domains at the study area: 1) in the unweathered, unaltered bedrock, 2) unweathered altered bedrock, 3) regolith of unaltered bedrock, and 4) regolith of altered bedrock. These mineralogical footprints will then be interpreted with the geochemical data against the background of high-resolution geophysical data, maps of integrated geological and geophysical rock properties and ASTER imaging, to determine how the deep crustal scale structures and hydrothermal fluid flow could be differentiated from the variation within unaltered bedrock.

The study takes place in the area around stratiform Abra Pb-Cu-Ba-Zn mineralisation in the sedimentary Edmund basin of the Proterozoic Capricorn Orogen in Western Australia. The project is part of the SIEF & MRIWA co-funded program “Distal Footprints of giant ore systems: Capricorn case study” and addresses questions that are aligned with the outcomes of the ongoing UNCOVER initiative.

Why my research is important

Indirect methods for discovering alteration related signatures leading to mineralisation in areas where outcrop is scarce to none are crucially important in the greenfields exploration around the globe. Developing best ways to use reflectance spectra (VNIR, SWIR, TIR) together with publicly available geoscience data is the core aim of this PhD project.
