摘要：
The Mount Isa Valley in northwestern Queensland, Australia hosts the world-class Mount Isa Cu deposit. Mineral mapping with airborne hyperspectral data has identified a suite of minerals. The spatial representing the effects of regional metamorphism, mineralisation-related hydrothermal alteration and weathering. The spatial occurrences and associations of these minerals reveal the effects of regional-scale metamorphism, hydrothermal alteration and weathering. In particular, it was found that that minor amounts of talc, a hydrothermal alteration mineral closely associated with Cu mineralisation, in the dark and fine-grained sedimentary rocks was mappable from the airborne hyperspectral data.
