摘　　要：为将遥感技术用于云南省牟定地区铀矿勘查,基于先进星载热发射和反射辐射仪(advanced spaceborne thermal emission and reflection radiometer,ASTER)遥感数据通过干扰去除+主成分分析(principal component analysis,PCA)方法,提取了研究区Al-OH、Mg-OH、CO_3~(2-)及铁染类蚀变信息;通过PCA及PCI Geomatica软件中的LINE模型自动提取了研究区线性构造,并绘制了线性构造密度图。最后结合地质资料,分析了研究区铀成矿与蚀变及线性构造的关系,并圈定一处成矿有利区。该研究可为该区后续勘查提供一定思路,同时也可为遥感技术在植被覆盖区矿产勘查提供一定参考。In order to apply remote sensing technology to uranium exploration in the Mouding area of Yunnan Province,based on ASTER(advanced spaceborne thermal emission and reflection radiometer)remote sensing data,the interference removal and PCA(principal component analysis)method was used to extract the Al-OH,Mg-OH,CO 2-3 and iron-stained alteration information in the study area.The lineaments in the study area were automatically extracted by PCA and LINE model in PCI Geomatica software,and the density map of lineaments was created.Finally,combined with geological data,the relationship between uranium mineralization and alteration and linear structures in the study area was analyzed,and a favorable mineralization area was delineated.This study can provide some ideas for subsequent exploration in the area,and also provide some reference for remote sensing technology in mineral exploration in vegetation-covered areas.
