摘　　要：水口山铅锌多金属矿田成矿条件复杂,矿床类型多样,作者从矿田特征、矿床特征及成矿规律3个方面开展研究,利用最新勘查、研究成果,升华成矿模式,指明下部找矿方向。取得以下主要成果:(1)矿床在垂向空间上表现"三层楼"式的成矿模式:近地表为金矿、中深部为铅锌硫金银矿床、深部为铜铁金矿。(2)二叠系栖霞组和当冲组是有利赋矿层位,岩体接触带+不整合接触面+破碎带是成矿良好富集空间,断裂为主要导矿构造,岩浆活动为成矿提供物源和热源。(3)斑岩型铜钼矿及蚀变岩型金矿是今后找矿的重点方向。The metallogenic conditions of the Shuikoushan lead-zinc polymetallic ore field are complex and the types of deposits are diverse. The author conducts research from the three aspects of ore field characteristics,deposit characteristics and metallogenic laws,and uses the latest exploration and research results to sublimate the metallogenic model to indicate Prospecting direction in the lower part. The following main results have been achieved:( 1) The ore deposit exhibits a"three-story"metallogenic model in the vertical space: near the surface is a gold deposit,the middle and deep part is a lead-zinc-sulfur gold-silver deposit,and the deep part is a copper-iron-gold deposit.( 2) The Permian Qixia Formation and Dangchong Formation are favorable ore-bearing horizons. The rock mass contact zone + unconformity contact surface + fracture zone is a good enrichment space for mineralization. Faults are the main ore-conducting structures,and magmatic activities are mineralization. Provide material and heat sources.( 3) Porphyry copper-molybdenum deposits and altered rock-type gold deposits are the key directions for future prospecting.
