arcuate fault

Based on researches on characteristics of the He125 fault,the authors have found that the arcuate fault is parallel to the fault strike and is the combination of fault-trough and fault-ridge,as evidenced from the profile.

通过对河125断层几何学特征的分析发现弧形断裂平行于断层走向剖面上表现为断槽、断脊组合;垂直于断层走向剖面上断层分为竖滑段、倾滑段和平滑段3段,生长指数规律为弧中大于弧翼,断层倾角规律为弧中小于弧翼。

The arcuate fault is the combination of fault trough and fault ridge,it is found from the section that is parallel to the arcuate,the fault can be separately divided into three parts,vertical-slip part,dip-slip part and horizontal-slip part from the section that is perpendicula.

为解释断层下降盘浊积砂体横向不均一的控制机理,从河125断层几何特征入手,剖析了断层形态与浊积砂体的关系,发现弧形断裂平行于断层走向剖面上为断槽、断脊组合;在垂直于断层走向剖面上断层可分为竖滑段、倾滑段和平滑段三段。
