赛博铜多金属矿位于西天山赛里木湖—四台海泉铜铅锌成矿带内,是该区域新突破的中-大型铜矿床.通过光薄片鉴定及流体包裹体分析得出,该矿床矽卡岩化发育,成矿期次可划分为退蚀变矽卡岩阶段(S1)、石英-硫化物阶段(S2)和石英.碳酸盐阶段(S3);包裹体类型为纯液相Ⅰ型、富液两相Ⅱa型、富气两相Ⅱb型、含子矿物Ⅲa型(含石盐子晶)和含子矿物Ⅲb型包裹体(不含石盐子晶);成矿流体显示初期以高温、高盐度,金属物质少量出现,成矿期大气降水混入,温度、盐度逐渐降低,流体沸腾、金属物质大量析出,再至晚期温度、盐度衰减并发育碳酸盐化的演化过程.C-H-O同位素显示,成矿流体早期以初始岩浆水为主,晚期以大气降水为主.S、Pb同位素表明成矿物质为壳-幔混源.总体上,赛博铜多金属矿是形成于活动陆缘岩浆弧环境的典型钙矽卡岩型矿床.
