PhD - Origins and significance of breccias in the Grasberg Cu-Au porphyry deposit, Indonesia

The Research Project

This PhD study will characterise the geology, alteration and mineralisation of breccias at the Grasberg porphyry Cu-Au deposit, Indonesia. Detailed core logging and (if possible) underground mapping will be supplemented with detailed petrographic and mineralogical characterisation to resolve the history of brecciation at Grasberg, its implications for the evolution of the hydrothermal system and for the understanding of ore genesis. Detailed breccia facies analyses will be used to help place brecciation events within the sequence of volcanism, intrusive activity and mineralisation at Grasberg, and to determine the processes that caused brecciation. Characterisation of individual breccia facies will also provide improved understanding of the mining and processing characteristics of breccia-hosted ore and will inform the development of new genetic and exploration models for breccia-hosted porphyry Cu-Au mineralisation.

Eligibility
