摘　　要：农戈山铅锌矿位于青藏川滇缅印尼"歹"字型构造体系与川滇南北构造带西缘交汇处,主要赋存于中生代中三迭统杂谷脑组地层与花岗岩体内接触带及外接触带的角岩内,矿体严格受NNW、近NS断裂带控制,从矿体形态、产状、规模及品位,矿石类型、组成及组构,围岩蚀变等方面论述了矿床的地质特征。主要控矿因素是地层、断裂构造和岩浆活动,其中断裂构造是最主要的控矿因素。通过对矿石S、Pb同位素分析和成矿温度、成矿时代研究表明,成矿物质来源于地层和岩浆岩,成矿温度为中低温,成矿时代为燕山期。认为该矿床成因类型为深源构造-热液成因,并具有多期成矿特征。同时,还归纳了主要找矿标志,为在该区内寻找这一类型矿床提供帮助。nungo River Hill lead-zinc in the Qinghai-Tibet Burma Indonesia ＂wicked＂-type structure system and the west- ern edge of the Sichuan-Yunnan north-south tectonic belt interchanges, major occun^nce in the Mesozoic Triassic Formation Commission Zagunao contact with the granite body zone and outside the contact zone in the corner of rock, ore strictly con- trolled by NNW, nearly NS fault control, from the ore body morphology, occurrence, size and grade, ore type, composition and fabric, wall-rock alteration, etc. discussed deposit geological features. The main ore-controlling factors is the strata, faults and magmatic activity, in which faults is the most important ore-controlling factors. Through the ore S, Pb isotope a- nalysis and ore-forming temperature, forming the times studies have shown that ore-forming strata and magmatic rocks from the ore-forming temperature in the low temperature, forming the Yanshan epoch. View that the genesis of the type （ff hydro- thermal deep-source structure ~ and have the characteristics of multi-phase mineralization. At the same time, it summari- zes the main indicators for prospecting, for in this type of deposits in the area looking for help.
