摘要
辽宁省三道河金矿床的矿石结构主要为它形—自形不等粒结构、溶蚀结构和碎裂结构。成矿类型为含金硫化物石英脉型和含金黄铁矿蚀变岩型。热液成矿期主要包含早期的粗粒黄铁矿—毒砂—石英成矿阶段,中期的石英—黄铁矿成矿阶段,晚期的石英—多金属硫化物成矿阶段;后期的阶段为石英、碳酸盐岩成矿阶段。
The ore structure of Liaoning province is the three river gold deposit mainly for its shape and structure, inequigranular euhedral textures and cataclastic structure. The metallogenic types are gold bearing sulfide quartz vein type and gold bearing pyrite altered rock type. Hydrothermal mineralization mainly includes early coarse-grained pyrite arsenopyrite quartz mineralization stage, the middle quartz pyrite mineralization stage, late mineralization stage of polymetallic sulfide quartz; late stage quartz, carbonate mineralization stage.
