Fluorite as indicator mineral in iron oxide-copper-gold systems: explaining the IOCG deposit diversity

Chemical Geology, 2020
Abstract Hydrothermal iron oxide-copper-gold (IOCG) ore deposits are globally important sources of Cu and Au. IOCG systems show many common features, but also considerable diversity in terms of geological setting, mineralization style and ore fluid characteristics.

Mineral systems with IOCG and affiliated deposits: Part 3 - Metal pathways and ore deposit model

open access: yes, 2022
Metasomatic iron-oxide and alkali-calcic alteration systems form a wide range of iron-oxide copper-gold (IOCG), iron oxide apatite (IOA) and primary critical metal deposits. Economic resources include Ag, Au, Bi, Co, Cu, F, Fe, Mo, Nb, Ni, Pb, Pd, Pt, Re, rare earth elements (both heavy and light REE), U, V, W and Zn.

Defining IOCG signatures through compositional data analysis: A case study of lithogeochemical zoning from the Olympic Dam deposit, South Australia

open access: yesOre Geology Reviews, 2019
The Olympic Dam Cu-U-Au-Ag deposit is dominantly composed of mineralised hematite-breccias and occurs entirely within the Roxby Downs Granite. Multivariate statistical analysis of a large whole-rock, 15 m-interval geochemical dataset (10,565 samples) was

Geophysical Signature of the Salobo IOCG Deposit and Implications for Mineral Exploration

19th Congress of the Brazilian Geophysical Society - Proceedings
Geophysics is a key in mineral exploration and has become even more important with advances in technology and the need to explore deeper targets. It helps reduce drilling risks and improve exploration efficiency. Salobo, a major IOCG (Iron Oxide Copper-Gold) deposit in the Carajás Mineral Province (1088.9 Mt at 0.62% Cu and 0.35 g/t Au), is located in ...
