摘　　要：云南省宁蒗县余家村矿区地处三江成矿带东缘、宁蒗-祥云铜钼成矿带北段,矿区地质构造复杂,岩浆活动强烈,具有较好的成矿远景。然而,矿区探采工作受到一定困扰,地质找矿仍未取得突破。究其原因,主要为对矿区的成矿条件和控矿规律认识不足。为此,本文根据近年来矿区地质勘探资料,系统性地总结了矿区金银多金属矿化带的地质特征,并从地层、构造、岩浆岩以及围岩蚀变等方面剖析其成矿条件和规律,最终提炼出矿区的金银多金属矿化带(M1)的成矿模式,以期为该地区地质找矿提供理论基础和技术支撑。Yujiacun Mining Area,Ninglang County,Yunnan Province,is located in the northern part of the Ninglang-Xiangyun Copper-Molybdenum Metallogenic Belt on the eastern margin of the Sanjiang Metallogenic Belt.However,there are still some problems in the exploration and mining work in the mining area,and the geological prospecting has not made a breakthrough.The main reason is the lack of understanding of the metallogenic conditions and ore-controlling rules in the mining area.Therefore,based on the geological exploration data of the mining area in recent years,this paper systematically summarizes the geological characteristics of the gold-silver polymetallic mineralization belt in the mining area,and analyzes its metallogenic conditions and rules from the aspects of strata,structure,magmatic rock and surrounding rock alteration.Finally,the metallogenic model of the goldsilver polymetallic mineralization zone(M1)in the mining area is extracted in order to provide theoretical basis and technical support for geological prospecting in the area.
