This course offers a comprehensive and updated introduction to Iron Oxide Copper-Gold (IOCG) deposits, one of the most important and debated mineral systems in modern economic geology. Aimed at geologists, geology students, and professionals in mineral exploration, this course focuses on understanding the key geological, geochemical, and structural features that characterize IOCG deposits globally.Based primarily on the updated classification and genetic models presented by Skirrow (2022), the course systematically explores the general features of IOCG deposits, their global distribution, and their occurrence in different tectonic settings, including orogenic, post-orogenic, and continental margin arc environments. A major emphasis is placed on the hydrothermal alteration zoning at the deposit scale, covering mineral assemblages and paragenetic sequences critical to ore identification.Through illustrated examples and scientific diagrams, learners will also become familiar with significant IOCG districts as well as the factors that influence their economic potential, including tonnage, grades, and associated elements like gold, uranium, and rare earth elements.The course also highlights key diagnostic features that help distinguish IOCG deposits from similar mineral systems, improving the accuracy of geological interpretations during exploration.Whether you are involved in research or mineral exploration, this course provides robust conceptual tools to interpret and recognize IOCG systems across different geological contexts.
