Mapping regional alteration patterns in the Curnamona Province using hyperspectral core scanning technology

Abstract

Before the advent of the CSIRO HyLogger technology (Huntington et al, 2004), semi-quantitative mineralogy was beyond the realms of practical application being expensive and time consuming. With a high density, high volume, spectral dataset, down hole mineralogy can be mapped, not only by presence, but also by abundance and chemical gradient. (Mauger, 2007) Four main mineral suites are presented here: White Mica/Clays (Al(OH)), Chlorite (Fe,Mg(OH)), Carbonate (CO3) and Fe Oxide.
