The fault movement and the direction of principal stresses may be determined by considering the relationship between the different secondary structures and en-echelon patterns.
因此可以通过这些次级构造和雁列类型的关系，来判断断层的运动和主应力方向。

Some large strike slip faults, such as the Xianshuihe fault, consist of main fault and several sub-faults, which are commonly arranged as enechelon (or parallel) pattern.
大的走滑断裂带，如鲜水河断裂，是由主干断裂及与其相伴的若干阶式（或平行）断裂组成。

The "multiple-order enechelon" pattern is one of the important geometric characteristics of the fault zone.
