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.


The following eligibility criteria apply to this project:

  • The project is open to Australian and New Zealand (domestic) and to international candidates;
  • Research must be undertaken on a full-time basis;
  • Applicants must already have been awarded a First Class Honours degree or hold equivalent qualifications or relevant and substantial research experience in an appropriate sector;
  • Applicants must be able to demonstrate strong research and analytical skills;
  • Ability to carry out field work and work with government and industry partner facilities and follow appropriate health and safety procedures;
  • Fluency in both Indonesian and English would be beneficial.

Candidates from the following disciplinary backgrounds are encouraged to apply.  Knowledge and skills that will be ranked highly include:

  • Degree-level undergraduate education in geology, economic geology, geochemistry or related subjects
  • Experience with ore deposits, volcanology
