摘　　要：对智利北部斑岩型铜矿区的卫星遥感影像进行处理,解译其线性构造、岩体及地层等控矿信息,并结合地质资料,分析出该区域的斑岩型铜矿位于近南北向大型断裂带与北东向次级断裂的交汇部位,近南北向断裂带为含矿热液的运移提供了通道,北东向的次级断裂成为含矿热液的储存场所。在遥感图像上呈深绿、草绿色调,近南北向展布的安山岩带为斑岩型矿床的围岩。含矿斑岩体呈浅红色调,北北东向展布,为中酸性超浅成侵入体。Northern Chile porphyry copper deposit of satellite remote sensing image processing,interpreting the linear structure,rock formations and ore control information,and with geological data,analyze the birth of the area porphyry copper deposit is located in nearly ns-trending large fault and north east to subprime fracture of the intersection part,nearly ns-trending fault zone for the migration of hot liquid containing ore provides channel,north east to subprime fracture become hot liquid containing ore storage sites.In remote sensing image,a dark green,Caolu tonal,nearly ns-trending exhibition cloth andesites take become porphyry deposit of the surrounding rock.Contain mineral is Jiangong porphyry tonal,north north east to exhibition cloth,the acid Chaojian into invading for body
