The research project will develop and test new strategies for the application of constrained and unconstrained inversion. The approach will be to apply the different inversion methods to areas with high data density such as Rosebery and Avebury. These areas will be used to calibrate outputs which in turn will be used to improve regional interpretations. In the case of constrained inversion, the type and density of “constraints” will be varied and assessed against the “known” or best available geology. Unconstrained inversion produces one of many possible explanations for any given data set. In contrast, “constrained” inversion maintains the topological significance of geological boundaries permitting geometry inversion. Hard constraints can be defined on the basis of geology, geochemistry or petrophysics. Ultimately, constrained inversion will likely produce a more accurate and precise rendition of the subsurface environment. One of the key outcomes from this approach will be an understanding of the strengths and weaknesses of the constrained inversion approach over a wide range of geological and geophysical environments. High quality magnetic and gravity data are available for western Tasmania (in the public domain) and it is likely this will be improved by the addition of data from MMG. Suitable candidates will have a background in Earth Sciences (Geology/Geophysics) and ideally one or more of Computing, Mathematics, or Physics, and the ability to take part in field data acquisition in remote areas and mine sites.
