怀安镇盆地南缘断裂构造地貌特征

Structure and Geomorphology Characteristics of the Southern Margin Fault of Huai’an Town Basin

基于遥感影像和1∶20万地质图成果资料,对怀安镇盆地南缘断裂沿线断层三角面、断层陡坎、冲沟裂点、断层冲沟等构造地貌以及典型断错剖面进行了野外调查。调查表明:断裂沿线分布大量典型的构造地貌现象,不同部位因断裂活动性的差异,其构造地貌特征各异;在一些地段冲沟壁中见断层断错剖面,断面是错断扇体的较新断裂。

Based on remote sensing images and 1:200,000 Geological map data,field investigation was carried out on fault landforms and typical fault sections such as fault triangle surface,fault steepness,fault waterfall and fault gully along fault line.The investigation shows that a large number of typical fault geomorphological phenomena are distributed along the fault line.Due to the difference of fracture activity in different parts,the characteristics of fault and fault geomorphology are different.In addition,fault sections are seen in the gully walls of some sections.The section is a relatively new fault of the fault fan.
