大兴安岭成矿带南段大座子山铜多金属矿成矿时代及其地质意义
P618; 内蒙古自治区大座子山矿床是大兴安岭成矿带南段近年来新发现的铜多金属矿床.该矿床矿体产于上侏罗统满克头鄂博组流纹岩内,成矿过程可以划分为白色石英-少硫化物(黄铁矿)阶段、烟灰色石英-多硫化物(黄铁矿、闪锌矿、方铅矿、黄铜矿和辉钼矿)阶段和方解石-硫化物(黄铁矿、方铅矿和闪锌矿)阶段.本次研究通过对石英-多金属成矿阶段辉钼矿开展Re-Os定年,获得6个辉钼矿模式年龄为134.4～136.9 Ma,加权平均值为135.5±0.8 Ma,与187Re-187Os等时线年龄(136.2±3.2 Ma)一致,表明其形成于早白垩世,不同于前人依据地层厘定的成矿时代.辉钼矿中Re含量为44.31×...

| Abstract_FL | The Dazuozishan deposit in Inner Mongolia is a recently discovered Cu-polymetallic deposit in the southern part of the Great Hinggan Range metallogenic belt.The orebodies in this deposit occurred in the rhyolite of Upper Jurassic Manketouebo Group,and the mineralization process was divided into three stages,i.e.,white quartz-minor sulfide stage(pyrite)stage,smoky quartz-polymetallic sulfide(pyrite,sphalerite,galena,chalcopyrite and molybdenite)stage and calcite-sulfide stage(pyrite,sphalerite and galena).This work conducted Re-Os dating of six molybdenite samples from the quartz-polymetallic sulfide mineralization stage,and obtained 134.4 to 136.9 Ma of model age with a weighted average age of 135.5±0.8 Ma.These ages are consistent with the 187Re-187Os isochronous age of 136.2±3.2 Ma.It is indicated that the Dazuozishan Cu-polymetallic deposit was formed in the Early Cretaceous,which was different from the previous age constrained by the Manketouebo rhyolite.Moreover,the Re content of the molybdenite ranged from 44.31×10-6 to 92.93×10-6,plotted between the crustal and mantle source regions.It is inferred that the ore-forming materials were derived from mixed crustal and mantle source.Based on the regional tectonic and magmatic evolution,the Dazuozishan copper polymetallic deposit was formed under extensional setting triggered by joint interactions between post-orogenic continental collapse of the Mongol-Okhotsk Ocean,and retreat and rollback of the Paleo-Pacific Ocean slab. |
