A unique Mo deposit associated with carbonatites in the Qinling orogenic belt, central China
Original language description
The Qinling molybdenum belt is a prominent metallogenic structure in central China hosting several significant porphyry- and porphyry-skarn-type deposits. The Huanglongpu Mo deposit in the north-western part of the belt is unique in that it is associatedwith carbonatite dykes, rather than felsic magmatism. The carbonatites are composed largely of Sr-Mn-rich calcite and characterized by high concentrations of Sr and rare-earth elements (REE), and stable-isotope values indicative of a mantle source (delta13CPDB = -- 6.7 and delta18OSMOW = 8.2). Molybdenite is associated with galena and REE minerals (parisite, bastnäsite and monazite). Both molybdenite and galena are characterized by high Re contents (up to 0.4 and 0.2 wt.%, respectively) and Re/(Mo, Pb)ratios approaching the primitive-mantle values. In contrast to the rock-forming calcite, the REE minerals are enriched in light REE, whose relative proportion increases from parisite-(Ce) [average (La/Nd)n = 2.1] to bastnäsite-(Ce) and m
