朱诺斑岩型铜矿床外围遥感找矿预测

Porphyry Copper Deposits of Zhunuo Peripheral Remote Sensing Prospecting Forecast

基于ETM+遥感数据源,利用ENVI遥感图像处理软件对云、雪被、第四系、水体、阴影等进行了掩膜;采用特征主成分分析技术对西藏自治区朱诺斑岩型铜矿床及其外围地区开展遥感羟基和铁染矿化蚀变信息提取,并进行了地质解译。据此圈定找矿远景区,为朱诺铜矿床外围地区开展找矿工作提供了先决条件。

Based on the data source of ETM+,we masked the cloud,snow,quaternary,water and shadow by ENVI remote sensing image processing software.Using the characteristics of principal component analysis method,we carried out remote sensing hydroxyl and iron staining mineralized alteration information extraction on the porphyry copper deposits in Tibet Autonomous Region,Zhunuo and its outlying areas.We had made geological interpretations.And according to it we delineated the ore-finding prospect area.It provides prerequisites for the work of looking for ore in the outlying areas of the copper deposits.
