The slices are truncated by the pre-Bulawayan erosion surface. 岩片受前布拉瓦约侵蚀面切割。
The erosional surface dissected by such valleys may subsequently become an unconformity in the stratigraphic sequence. 被这种河谷切割的侵蚀面后来可能成为地层层序中的不整合性。
As the ancient plain uplifted, it formed the mountain erosion surface with the potholes on its surface. 准平原及壶穴最后被抬升到山地的顶部，构成了山地夷平面。
This paper also analyzes the relation between the slopes and elevations and gets the information of planation surfaces in the Dabie orogenic belt. 本文统计分析了坡度与高程之间的相互关系，并提取了夷平面信息。
