Abstract：The Rovieng Cheung dome structure is located in the Siem Reap-Stung Treng metallogenic belt with the main mineral of iron in northern Cambodia. The discovered iron deposits, including Gygoye iron deposit, Rock Mountain iron deposit and Nuodongan iron deposit, mainly consist of supergene residual deluvial ores and primary ores, with orebodies occurred in layered, stratoid, cystic and lenticular forms, and mineral assemblages of hematite-magnetite-limonite. The deposits in large unproven areas within the dome share similar metallogenic geological setting with the known deposits. To rapidly evaluate the iron metallogenic background in the unproven areas, the low-altitude high-precision magnetic survey by trike is conducted on the basis of geological and remote sensing information, combined with the ground magnetic survey for verification. A total of 12 prediction areas are delineated, among which 4 are first-level prospecting targets as the main direction of next step.
