Maoniuping REE deposit, Mianning Co., Liangshan Autonomous Prefecture, Sichuan Province, China

StandardDetailedBy ChemistryMineral Photos (22)MapsSearch Google

World's second largest REE deposit, with proven reserves of 0.4 million tonnes of ore grading at 2% REE oxides. The deposit consists of bastnäsite-baryte-carbonate veins, which are associated with nordmarkite and hosted in a carbonatite-syenite complex (K-Ar ages of arfvedsonites and biotites: 27.8-40.3 Ma).
Located within the Panzhihua-Xichang ("Pan-Xi") rift, a N-S trending major regional pull-apart graben structure developed during the late Paleozoic.


The coordinates given are those of the next population center.
