The current paradigm for understanding the formation of ore shoots in many ore deposit types is flawed.
A new paradigm centred around how fluid flow is organised in the lithosphere leads to new concepts for exploring for ore shoots.

• Proposed that most ore deposits can be considered as forming in transient fluid-exit conduits, associated with the episodic rupture of over-pressured reservoirs at depth (Hronsky, 2011).
• Represent examples of self-organised critical systems.
• Oreshoots not following kinematic model
• Vertical stockwork pipes with no bounding shear zone/fault
• Complex oreshoot networks
• Multiple hydrothermal events widely spaced in time using same pathway
• Ultrahigh grade veins
Australia often incorrectly perceived as mature – 80% of landmass under cover, nation-wide commitment and alignment of geoscience initiatives to overcome the cover challenge – turning cover into opportunity, recent exploration shows the success of such commitment in...

This lecture will explore the chemical evolution of fractionally crystallising, intermittently replenished, intermittently tapped magma chambers at Moho-type pressures and shows that these processes tend to produce, after several replenishment and crystallisation cycles, except...

Chemical analyses of least-altered samples of subduction-generated intrusives parental to 50 major Au deposits and 57 Au+Cu deposits of Phanerozoic age worldwide are compared with analyses of thousands of volcanic and hypabyssal igneous rocks from unmineralised Neogene- Quatern...
