| Summary | (Plain Language Summary, not published)
This presentation for the 2019 Geological Survey of South Australia IOCG workshop illustrates the evolution of alteration facies within mineral systems
that host iron oxide copper-gold (Co-Ag-Bi-REE-U) (IOCG) and affiliated deposits followed by examples of the spectrum of deposit types formed and the commodities (base, precious and critical metals, iron, uranium, thorium, etc.) precipitated as a
function of the metasomatic growth of the system, ingress of syn-metasomatic fluids and magmas, and tectonic activity. Iron oxide and alkali-calcic alteration (IOAA) facies are also shown to be metal pathways to ore and to serve as mappable criteria
for mineral potential assessment. The case examples used include the Canadian Great Bear magmatic zone, Central Mineral Belt and Romanet Horst in Canada as well as the Cloncurry district and the Olympic Copper-Gold Province in Australia. The research
was conducted under the Uranium project of the Targeted Geoscience Initiative program of NRCan. |
