Olympic Dam
South Australia, Australia
IOCGCu
- Type
- Iron oxide copper-gold (IOCG)
The largest IOCG deposit in the world (over 9 Gt of ore), of Proterozoic age (about 1590 Ma). Highly variable δ34S (-8 to +18 ‰), owing to multiple sources. Highly radiogenic crustal lead (206Pb/204Pb of about 18.5 to 20.5).
