摘　　要：以下分析了刁泉铜银接触交代—热液型矿床的成矿地质背景及矿床地质特征,以断裂构造为主,分布于岩体边缘,控制了燕山期岩浆,岩体边缘奥陶与侏罗系地层常见角岩化、矽卡岩化、大理岩化。利用TM影像特征及蚀变矿物波谱特征,采用主成分分析及波段比值、假彩色合成等方法,提取了绢云母化、钙铝榴石化、绿泥石化蚀变信息及线—环形构造,成矿有利部位是线—环交切、蚀变异常密集部位。The following analyses DiaoQuan contact metasomatic copper silver-hydrothermal type deposit metallogenic geological background and geological features, mainly on fracture structure, distributed in the edge of the rock mass, the control of the yanshan period magma, common Angle edge of ordovician and Jurassic strata rock mass lithification, silicon card lithification, Dali lithification. Using TM image features and the alteration mineral spectrum, using principal component analysis, band ratio and false color composite method, extract the sericitization, calcium aluminum pomegranate petrochemical, chloritization alteration information and line- ring structures, mineralization favorable area is the line-pay cut, alteration anomaly populated area.
