A Research Review of Iron Oxide Copper‐Gold Deposits
Iron oxide copper‐gold (IOCG) deposits are a research focus of the current ore deposit geology, and have attracted much attention among the worldwide geologists and exploration experts due to their shallow depth, a wide variety of mineral species and large scale. This paper presents a review of the present IOCG deposits research, which includes the definition of IOCG deposits, temporal and spatial distribution, ore‐forming environments, ore‐forming magmatic rocks, their geological features, ore‐controlling structures and ore‐bearing rocks, mineralized alteration zoning, and their genesis and ore‐forming process. This work also proposed the ore prospecting direction of IOCG deposits from a trinity model of metallogenic geological bodies, metallogenic structure surface and metallogenic information signs, and discussed the existing problems of the IOCG deposits research.
