01-12-2017· The Bayan Obo deposit is situated on the northern margin of the North China Craton (109°59′ E; 41°48′ N), which was formed through accretion of microcontinental blocks from 2.2 to 1.85 Ga (Zhao et al., 2003).In the Mesoproterozoic period the northern part of the craton underwent rifting (Yang et al., 2009, Zhao et al., 2003), resulting in the formation of numerous …
The Bayan Obo REE-Nb-Fe deposit is a typical carbonatite-related deposit, which indicates the rare earth element (REE) resources originated from local carbonatite magma [1,2].However, there is still controversy about whether the abnormal REE enrichment was initiated during the intrusion of dolomitic carbonatite melt, or during hydrothermal metasomatism which overlapped a …

01-05-2016· Bayan Obo ore deposit is the largest rare-earth element (REE) resource, and the second largest niobium (Nb) resource in the world. Due to the complicated element/mineral compositions and involving several geological events, the REE enrichment mechanism and genesis of this giant deposit still remains intense debated.
Hydrothermal processes have played a significant role in rare earth element (REE) precipitation in the Bayan Obo REE-Nb-Fe deposit. The poor preservation of primary fluid inclusions and superposition or modification by multiphase hydrothermal activities have made identification of physico-chemical conditions of ore-forming fluids extremely difficult.
