Crustal Evolution and Geodynamic Setting of the Fraser Zone, Western Australia

Abstract

The Fraser Zone in the Albany–Fraser Orogen, Western Australia, represents a crucial site for studying Proterozoic crustal evolution and mineralization. This research investigates its complex tectonic and magmatic history through detrital zircon analysis, Sm–Nd isotopes, and U–Pb apatite thermochronology. Findings reveal a back-arc setting influenced by heterogeneous magma sources and multiple thermal events. This study provides new insights into crust-mantle interactions and aids in refining exploration models for Ni–Cu–Co deposits in high-grade terranes.
