摘　　要：个旧锡矿高松矿田层间氧化矿形态可分为缓倾斜矿体和陡倾斜矿体,其受断裂破碎带、层间剥离带、层间破碎带控制,分布于岩体外接触带的中三叠统个旧组层间破碎带中;矿床一般产出于中三叠统个旧组卡房段的T_(2)g_(1)^(6)、T_(2)g_(1)^(5)层中。本文综合分析研究区内控矿因素和成矿规律,并结合前人研究资料,归纳了研究区的地质、地球物理和地球化学找矿标志,构建了“三位一体”成矿模式和找矿模型,对于个旧锡矿区开采工作具有一定的参考意义。The interformational oxidized tin ore is occurred in two kinds of gently dipping or steeply dipping ore bodies in layer T_(2)g_(1)^(6)andT_(2)g_(1)^(5)of Kafang Member of Middle Triassic Series.They are controlled by fractured fault zone,interformational stripping zone and interformational fractured zone within the interformational zone of Triassic Gejiu formation of the outer contact zone of a intrusive body.This paper analyzes comprehensively the ore-controlling factors and metallogenic regularity and summarizes the geological,geophysical and geochemical prospecting marks on basis of the previous data and the Trinity metallogenic and prospecting model is built for the study area.It is of a certain significance and can be referred to for the future prospecting.
