| 摘 要： | ASTER数据的光谱和空间分辨率均具有一定优势,适合于中等比例尺的矿产预普查。为了探讨ASTER数据应用于铝土矿预普查的效果,通过对ASTER图像彩色合成、地质解译及异常信息提取,对豫西渑池地区的铝土矿进行了预普查试验。结果表明,在北方基岩裸露地区,应用ASTER数据圈定"赋矿影像单元"和提取铝土矿遥感找矿信息能获得较好的效果。

| Abstract: | ASTER data have the superiority of ground resolution and spectral resolution,and hence are suitable for medium-scale pre-survey of mineral resources.For the sake of studying the effect of applying ASTER data to bauxite pre-survey,The authors made an experiment that included image color composite,geological interpretation,and remote sensing extraction of anomaly information in Mianchi area of Western Henan.The result shows that the ASTER data are effective in delineating "ore-bearing image unit" and extracting remote sensing information in exposed bedrock areas of northern China. |
