Gold in iron oxide copper–gold deposits -

01.01.2016  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 provinces are compiled in this paper. The gold grades in these IOCG deposits
