Iron oxide copper-gold (IOCG) deposits – A review (part 1 ...

2022-1-1 · The diverse group of iron oxide copper-gold (IOCG) deposits has been one of the most contentious classes of ore deposits since its recognition as a new type in the mid 1980s to early 1990s. Central to the debates have been the issues of definition, classification, the roles of magmatic versus and non-magmatic sources of fluids and metals, and ...

Gold in iron oxide copper–gold deposits - ScienceDirect

Iron oxide copper–gold (IOCG) deposits contain economic or anomalous gold, and the gold distribution is important both for its economic significance and ore genesis. However, the gold distribution in IOCG deposits and its controlling factors remain unclear. The gold grades and tonnages of selected thirty-six deposits in some well-defined IOCG ...
