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.
