Abstract

Abstract: Based on the filed investigation and data analysis of the tectonics、sediments and landform, the authors has studied a special active tectonic unit developed in the compressional mountain fringe of the Hexi corridor—trumpet asymmetric graben. It looks like a flaring river mouth in plane developed at arcuate mountain fringe in shape, but a asymmetric graben confined by active fractures and developed in the specified tectonic position in fact. This is a representative form of tectonics in the compressional active fractures zone, the Gulang asymmetric graben is one of the them. The paper has approached its developed model.

Key words: developed model, compressional mountain fringe, tectonic landform, trumpet asymmetric graben

摘要： 根据构造、沉积和地貌的野外调查与资料分析研究了河西走廊压性山地边缘所发育的一种特殊的活动构造地貌——喇叭形不对称地堑。它在呈弧形的山地边缘平面上为喇叭形河口，实际上是发育在特定的构造部位、由断层围限的不对称地堑。它是挤压型活动断裂带中有代表性的构造现象，古浪不对称地堑便是其中之一。探讨了该不对称地堑的发育模式。
