Genesis And Prospecting Perspective Of Xianglushan Iron Deposit, Sichuan Province, China

More than 30 ore bodies have currently been discovered in the Xianglushan iron deposit in the central part of the Huili-Dongchuan Aulacogen. The main orebody is stratiform or stratoid within the volcanic sedimentary metamorphic rock of the Paleo-Mesoproterozoic Yinmin formation. Minor ores intrude as veins in the country rock and the mineral components of the iron ore are mainly magnetite and hematite. The ore evolved through the Paleo-Mesoproterozoic submarine volcanic eruption deposition period and the Neoproterozoic iron slurry superimposed transformation, and is identified as a sedimentation-transformation-type deposit. A study is conducted on the regional metallogenic background and geological characteristics of the ore deposit; results show that the ore-forming setting of the Xianglushan iron ore is excellent and that the potential of finding large-scale rich iron deposit is considerable.
