Stage 1: Construct the mafic ocean floor.
- Upwelling of mafic magmas from the mantle. Mafic magma (green) transferred to the ocean floor through major dykes complexes.
Stage 2: Subduction commences and development of major oceanic faults, about 165 million years ago
- With faulting, mafic and felsic magmas are generated by melting of the down going slab and extruded onto the ocean floor".
- Fault zones within these felsic volcanic centres channel hydrothermal fluids to the ocean floor where they deposit precious metal-rich VMS ore deposits.
Stage 3: Deformation - thrusting and uplift
- Ocean closes and the volcanic pile is compressed, deformed and uplifted into a mountain belt.
- The volcanic sequence is piled upon itself in a series of stacked rock packages.
- Within this deformed sequence of volcanic rocks, ore bodies are now at different structural levels which appear as separate belts of ore deposits on the geology map.
Stage 4: Deposition of sedimentary rocks
- Uplift of the volcanic sequence is accompanied by erosion at ~ 140 million years ago.
- The products of this erosion were deposited in a basin that incrementally on lapped and then covered the volcanic rocks with a series of layered sedimentary rocks.
Stage 5: Renewed faulting
- At an undetermined time after the deposition of the 140 million year old sedimentary rocks, the entire rock column is subjected to a period of faulting.
- Faulting exploited older faults resulting in a dislocation of the volcanic and sedimentary rock sequences.
Stage 6: Erosion of this landscape
- For the last ~100 million years up to the Present, re-sculpturing of this volcanic and sedimentary landscape by younger deformational events and erosion has created this spectacularly rugged landscape.
