China's second largest REE deposit (originally started as a molybdenum mine), with proven reserves of 0.4 million tonnes of ore grading at 2% LREE oxides. The deposit consists of bastnäsite-baryte-carbonate veins, which are associated with nordmarkite and hosted in a Himalayan alkalic 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 mineral paragenetic sequence of chevkinite, allanite, and bastnäsite in the Maoniuping mining area comprehensively records the transition of the overall environment from high-temperature, low-oxygen fugacity conditions to low-temperature, highoxygen fugacity conditions in the magmatic–hydrothermal system. Oxygen fugacity plays a significant indicative role in the selective enrichment of REEs. Under low-oxygen fugacity conditions, rare-earth minerals are more prone to enrich Ce, Pr, and Nd, whereas high-oxygen fugacity environments favor the enrichment of La. Under low-temperature, high-oxygen fugacity conditions, LREEs exhibit a clear preference for selective enrichment in bastnäsite, which is more conducive to the formation of large-scale mineralization. The results reveal a crystallization sequence of chevkinite → allanite → bastnäsite, accompanied by a progressive decrease in the content of Nb, Ta, Zr, Hf, Sr, and Ba. This trend indicates continuous magmatic–hydrothermal evolution of the ore-forming fluids. REE enrichment exhibits distinct stages: early-stage enrichment of HREE, mid-stage enrichment of Ce, Pr, and Nd, and late-stage dominance of La. For chevkinite (δCe = 0.98–1.11, avg. 1.05; δEu = 0.75–0.87, avg. 0.82) and bastnäsite (δCe = 0.81– 1.15, avg. 0.88; δEu = 0.58–0.79, avg. 0.66), the evolution process of the continuous increase in oxygen fugacity within the metallogenic system is recorded.
Maoniuping (3.17 Mt REO at 2.95 wt%) formed between 26–28 Ma. The main exposed lithologies at Maoniuping are a Neoproterozoic composite alkaline granite batholith together with a rhyolitic volcanic succession.
