| 摘 要： | 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究时利用了陆地卫星TM图像与区内的地质地球物理资料进行综合解译,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、冰水扇等冰川作用遗迹.通过对冰蚀、冰碛地貌的研究,发现它们之间是一系列有规律的组合,有其密切的成生联系,是更新世多次冰川作用的结果.

| Abstract: | In the Beimen River basin there is Pleistocene deposit widely spreading with a significant depth.When studying the backgroud condition of the formation of the building placer,using TM images and local geologic and peophisic data for integrated interpretation,the author found rich relics of glacial pavement such as Zungenbecken,cirque,glacial tough,moraine bar,moraine fan.outwash apron,etc which are caused by glaciation.Analysis of the terrains of glacial crosion and glocial drift shows that they are a range of regular compositions interrelated in structure and resulting from multiple times of glaciation in the Pleistocene epoch. |
