摘　　要：在河南省桐柏县刘山岩铜锌多金属矿区开展深部及外围预查,对矿床进行了地球化学异常特征及评价标志研究。矿床的异常元素组合主要为Cu、Zn、Pb、Ag、Ba、Mo、Cd;次为Mn、Bi、As、Ga、Ge、V、W;矿床实用元素轴向分带序列由上至下依次为Cu-Zn-As-Ga-Ag-Pb-Mo。同时,根据已知矿和非矿异常特征、元素组合及分带特征、元素比值特征等建立了矿床的找矿评价地球化学标志。In order to carry out pre-investigation in the depth and the periphery of the Liushanyan Cu-Zn deposit in Tongbai County of Henan Province,the author studied characteristics of geochemical anomaly and evaluation criteria of this deposit.The major anomaly combination of elements is composed of Cu,Zn,Pb,Ag,Ba and Mo,（Cd）,followed by Mn,Bi,As,Ga,Ge,V and W.Axial zoning sequence（from top to bottom） is Cu-Zn-As-Ga-Ag-Pb-Mo.Based on the characteristics of ore-related and barren anomalies,combination and zoning of elements,and elemental ratios,the author established criteria or indicators of geochemical prospecting.
