READING THE OROGENIC RECORD: MINERAL TEXTURES, METAMORPHIC PROCESSES & CRUSTAL EVOLUTION

Grant number: DP0557013

Abstract

This research will produce new information relevant to the geological evolution of the Australian plate by direct examination of appropriate areas and by providing constraints on the geological processes that formed Australia. The metamorphic belts we propose to study host several of Australia's major mineral deposits, economically-important resources generated as a consequence of orogenesis, intrinsically linked to their metamorphic evolution. The methodologies developed here and the resulting greater understanding of orogenesis will have direct application to many aspects of ore formation.
