磐石茶尖岭上汪家地区金及多金属矿地质特征及其找矿前景

Geological features and prospecting potential of Shangwangjia area gold and polymetallic ores in Chajianling, Panshi

矿体受北西向断层破碎带控制,矿石类型为石英脉型,矿石矿物有褐铁矿、黄铁矿、磁黄铁矿、钛铁矿、黄铜矿、镍黄铁矿等;脉石矿物有石英、碳酸盐矿物等,其中石英为主,是金、银、铜镍矿物的主要载体矿物。最高品位:Au:1.17×10^(-6);Ag:54.4×10^(-6);Cu:0.33×10^(-2);Pb:0.94×10^(-2)。矿体围岩比较复杂,随着控矿断裂的延伸而穿切不同的围岩:绢云片岩、细砂岩、细粒闪长岩、闪长玢岩等,围岩蚀变类型有硅化、碳酸盐化、绢云母化等,其中硅化与金、银矿化关系密切。

Ore bodies are controlled by the NW fault fracture zone, ore type is quartz vein type, the ore minerals are limonite, pyrite, pyrrhotite, ilmenite, chalcopyrite and pentlandite, etc; Gangue minerals such as quartz, carbonate mineral, is the main carrier minerals of gold, silver, copper-nickel mineral.The highest grade： Au：1.17×10^（-6）;Ag：54.4×10^（-6）;Cu：0.33×10^（-2）;Pb：0.94×10^（-2）. With the extension of ore-controlling fracture, different surrounding rock is cut through： sericite schist, fine sandstone, fine-grained diorite and diorite porphyrite, etc., wall rock alteration types have silication, carbonatization and sericitization, and solidification is closely related to gold and silver mineralization.
