Surface planation
面夷───Surface planation
As important constituent of planation surface, the weathering crust is the spot of planation surface research to cut into.───作为夷平面的重要组成部分,风化壳是夷平面研究的切入点。
planation surface in west Yunnan was universally deformed, and the deformation is generally belonging to two types; one is the large area tilting deformation.───夷平面普遍受到两种变形,一种是大面积的掀斜变形,夷平面高度由西北向东南方向递减;另一种为断裂变形,夷平面呈地堑式下降或地垒式上升。
The dating of planation surface is still an intractable problem.───而另一方面,夷平面的定年仍是一个棘手的问题。
