TM IMAGE INTERPRETATION FOR GLACIAL GEOGRAPHY IN THE NORTHWEST OF QIONG

在北门江流域更新世沉积广布、厚度巨大。在对区内的建筑砂矿进行成矿背景条件研中，利用了陆地卫星ＴＭ图像并与区内的地质地球物理资料进行综合分析，发现了区内的冰蚀台面、冰洼、冰斗、冰川槽谷和冰碛堤、冰碛裙和冰水扇等冰川作用遗迹。通过对冰蚀、冰碛地貌的研究发现它们之间内在的成生规律。

In Beimen river basin, the Pleistocene deposits is wild and tremendous thick. By applying land satellite TM image and geophysical exploration data to comprehensively study the construction sandy ore-forming background. Meanwhile, the author interprets some glacial relics. Though studying these glacial relics, the author believs that the glacial geography is a series of ordered composition, and formed by several glacial activities during the Pleistocene.
