| Abstract: | Bayan Obo ore deposit is the largest REE deposit,and the second largest Nb deposit in the world.It is also a large iron deposit.It has been intensively studied on mineralogy,geochronology and ore-forming processes since it was discovered.Due to the complicated element and mineral compositions and activities of several geological events,the ore-forming mechanism is still controversial.Six models are summarized by this paper,including the sedimentation followed by metasomatism,the replacement of sediments by the outpouring of mantle-derived fluids in sea-floor,the mineralization by subduction,the microlite mound followed by metasomatism,the mineralization by meteorite impact,and the carbonatite intrusion.These models are reviewed here to provide information for further investigation on the Bayan Obo deposit. |
