喜马拉雅造山带中段北坡构造地貌初步研究
Primary Study on Tectonic Landforms in Northern Part of Middle Himalayan Orogen
【摘要】 研究区位于喜马拉雅造山带中段北坡,构造地貌丰富、典型.本文在野外调查的基础上,将区内构造地貌分为断裂构造地貌、花岗岩构造地貌、夷平面构造地貌、冰川构造地貌、水系及阶地构造地貌和土林构造地貌等类型,并对这些构造地貌特征进行初步分析描述,为喜马拉雅造山带的构造隆升研究提供了地表构造地貌上的有力信息.
【Abstract】 The study area lying in the north slope of the middle part of Himalayan orogen involves abundant representative tectonic landforms. Based on the field survey, this paper works out several tectonic landforms: faulting landforms, granite landforms, planation surface landforms, glacier landforms, water system, terrace landforms and earth wood landforms. Then it describes and analyzes the characteristics of those tectonic landforms. All these have provided forceful information for the research of Himalayas tectonic uplifting and its surface landforms.
