Abstract
Next Generation Mineral Mapping (NGMM) is a CSIRO Minerals Down Under initiative aimed at developing spectral sensing capabilities in collaboration with the government geological agencies across Australia for delivering a new range of pre-competitive geoscience information at low cost to the resources industry. A 2 year multi-organisational project was established in July 2006 and involved the collection of 25000 km2 of airborne HyMap imagery (~250 flight-lines at 5m pixel resolution), over 100 ASTER scenes and associated ground and laboratory validation data collected along major structural/geological corridors across Queensland. This paper will show the effectiveness of software/methods for delivering seamless, accurate mineral and geologic maps from HyMap and ASTER data through comparison with field and laboratory validation data, as well as some geological case histories including. - Geothermometric (metamorphic temperature) mapping using clay physicochemistry; - Local to regional hydrothermal alteration cells associated with the Century Pb-Zn and Starra Au-Cu deposits; and - Associated environmental indicators from remote spectral data for resource development, including dust mapping/monitoring. These results and capabilities also have major implications for mapping soil mineralogy and related properties/processes at local-, catchment- and continental-scales, including soil pH, metal availability, water (content, permeability/runoff), soil loss and organic carbon stocks. The mineral maps and associated data from this project are available on the web (www.em.csiro.au/NGMM).
