陕西木龙沟—黄龙铺地区钼、铼、稀土资源量概况及铼、稀土赋存特征

木龙沟—黄龙铺地区已探明小型—大型钼—铼—稀土矿床20多处。矿床成因类型有斑岩型、斑岩—矽卡岩型、矽卡岩化爆破角砾岩型和碳酸岩脉型四种。钼潜在资源量>298万吨,已探明约76.24万吨;伴生铼潜在资源量>644t,已知约367.37t;稀土潜在资源量为>872万吨,已探明约95.31万吨。有钼就有铼。矽卡岩型和碳酸岩脉型钼矿较斑岩型钼矿富铼。2H1+3R型辉钼矿较2H1辉钼矿富铼。稀土主要产于碳酸岩脉型钼矿中,或为独立脉状。

GENERAL SITUATION OF MOLYBDENUM,RHENIUM AND RARE EARTH RESOURCES AND OCCURRENCE CHARACTERISTICS OF RHENIUM AND RARE EARTH IN MULONGGOU-HUANGLONGPU AREA OF LUONAN COUNTY

More than 20 small and large-scaled molybdenum-rhenium-rare earth deposits have been discovered in Mulonggou-Huanglongpu area.The genetic types of the deposits are porphyry type,porphyry-skarn type,skarnized blasting breccia type and carbonate dike type.The potential resources of molybdenum are more than 2.98 million tons,in which about 762,400 tons have been proved;the potential resources of associated rhenium are more than 644 tons,in which 367.37 tons are known;the potential resources of rare earth are more than 8.72 million tons,in which 953,100 tons have been proved,showing where molybdenum is,where rhenium could be found.Skarn type and carbonate vein type molybdenum deposits are richer in rhenium than porphyry type molybdenum deposits and 2H1+3R molybdenite is richer in rhenium than 2H1 molybdenite.Rare earth occurs mainly in carbonate vein-type molybdenum deposits or in independent veins.
