Abstract:
The Pilgangoora lithium-tantalum project encompasses a globally significant Li-Ta pegmatite district which formed in the late-Mesoarchaean, along the western margin of the East Pilbara Terrane in Western Australia. Regional field mapping, coupled with local petrographic and microanalytical investigation into lithium and tantalum mineralisation at Pilgangoora, have allowed a first step towards developing a mineral system-type model for raremetal pegmatites, that looks beyond the internal features of the trap site, and considers factors such as the triggers, potential sources, and pathways of rare-metal pegmatite magmas.
