These features are considered important because of their ability to act as conduits to the upper crust for metal-bearing hydrothermal brines and magma originating deeper in the crust and in the mantle. At the same time there is general acceptance amongst mineral explorers that future exploration will be directed at targets at increasingly greater distances below the surface. These two factors require the best possible ‘pictures’ of the geology at depth, which only geophysical methods can provide. Research in the characterisation of mineralised terrains is currently concentrated in Western Australia where we are working with the Geological Survey of Western Australia (GSWA) on a major project funded by the Western Australian Government’s Exploration Incentives Scheme (EIS).
This work involves studies of selected terrains in Western Australia which are considered to be poorly understood and, as a consequence, under explored. The terrains that will be studied during this project are the Arunta Orogen, Musgrave Province, Capricorn Orogen and Kimberley Province. Each area is considered on a case-by-case basis but common components of the analysis include:
