This project involved Phaedra Upton, Dave Craw and Mike Begbie (OceaniaGold Ltd).
Also, please visit the Macraes Mine web pages for more information on department-wide research efforts at Macraes.
We have used three-dimensional mechanical models to investigate:
- Mechanical controls on extensional shear vein formation within a thrust zone at Macraes (fig1&2)
- The effect of deposition of graphite on localisation of shear within a midcrustal shear zone (fig3)
