摘　　要：水口山矿田地处南岭成矿带中部,矿田内矿床众多,矿种丰富,共发现康家湾铅锌金银矿床、老鸭巢铅锌金矿床、龙王山金矿床、仙人岩金矿床等11个主要矿床。矿床成矿受多期次构造、成矿热液多次叠加作用,成矿延续时间长,矿化范围广。本文通过结合矿田区域地质、地球化学背景,分别分析矿田地层、构造、岩浆岩的微量元素地球化学特征,浅析水口山矿田成矿成晕机理及成矿规律。Shuikoushan Ore Field is located in the middle of Nanling metallogenic belt.There are many deposits and rich minerals in the ore field.Eleven major deposits have been found,such as Kangjiawan lead-zinc gold deposit,Laoyachao lead-zinc gold deposit,Longwangshan gold deposit and Xianrenyan gold deposit.The mineralization of the deposit is subject to multiple superimposition of multistage structures and ore-forming hydrothermal solutions,with a long mineralization duration and a wide mineralization range.Based on the regional geological and geochemical background of the ore field,this paper analyzes the trace element geochemical characteristics of the strata,structures and magmatic rocks of the ore field respectively,and analyzes the metallogenic halo forming mechanism and metallogenic regularity of Shuikoushan orefield.
