摘要:
辽宁五龙金矿位于营口?宽甸古隆起的南部,鸭绿江成矿带西北侧.该矿的主要载金矿物为黄铁矿,针对m2?3,m2?6和m4?2矿脉黄铁矿标型特征的系统研究表明:其黄铁矿的S/Fe为1.90~1.98,属亏硫型;在-454~-609 m标高范围内ω(Fe)/ω(S+As)为0.888~0.908,微量元素(As+Sb+Se+Te)组合、(Ag+Cu+Pb+Zn)组合和(Co+Ni+Ti+Cr)组合在-530 m标高以下具有首尾晕显著叠加同步增加的变化;成矿延伸指数(γ)变化为29.5%~64.5%,呈现波动式变化,且在-609 m标高出现明显折返趋势,表明-454~-609 m标高范围属于矿床的中上部位;此外,黄铁矿出现率平均为81.28%,垂向上呈“S”型波动,-609 m标高P导型出现率在80%以上,并有下延增大趋势,同样说明在-609 m标高下部仍具较好找矿潜力.矿石中微量元素Ag,Cu,As,Pb,Bi高值区相互叠加,在南部-609 m标高处见有两处高值叠加区向下尚未闭合,暗示有向下延伸的趋势.综合认为南部矿体向下找矿前景更大.
