Under the banner of CReST – the Centre for Resource Science and Technology – a significant number of academics working on mineral resource geoscience, focusing particularly on understanding the fundamental geological processes that promote formation of ore deposits. Many of us focus on understanding the mantle to crustal scale geochemical processes the lead to ore localisation, and others focus on understanding the geodynamic, magmatic and structural processes that go hand in hand with the geochemistry. Some of us collaborate with metallurgists to solve problems in metal recovery, and others work on the geology of hydrocarbon and geothermal resources and nuclear waste disposal.
