GEOLOGY AND GEOCHEMISTRY OF IRON OXIDE

COPPER-GOLD DEPOSITS

LEAD: ADRIAN FABRIS, GSSA

Adrian Fabris joined the Geological Survey of South Australia in 2000 where he has since worked on projects related to regolith geoscience, economic geology and exploration geochemistry throughout South Australia and on commodities such as copper, heavy mineral sands, uranium, base metals and specialises in iron oxide copper-gold deposits.

Iron oxide copper-gold (IOCG) deposits form some of the world’s most significant mineral deposits. Since the discovery of Olympic Dam, IOCG deposits have been recognised elsewhere in the Gawler Craton and in a number of terranes world-wide. Understanding of IOCG systems have been developed over many years of research and discovery.

This workshop will provide a background understanding of IOCG systems, their characteristics, and discuss practical geochemical approaches to exploration for this style of mineral deposit. Drill core from world-class hematite-rich IOCG deposits will be on display along with examples of the diversity of alteration and mineralisation associated with these systems.

Specific focus will include

· Key deposit characteristics

· Alteration facies and their application to mapping the mineral system

Geochemical-based exploration approaches
