本文描绘了交错断层或剪切带与岩石圈板块三联点之间的类似性。矢量分析表明,断层的交汇对刚性断块来讲总是不稳定的,但可因扭折带的出现或各断块内体积的变化而稳定化。这种方法可对任意断层的可能产出位置及围岩应变方向作出迅速的估计,并可检验用于解释野外数据的动力学模型。
This article describes the similarities between the triple point of a staggered fault or shear zone and a lithospheric plate. Vector analysis shows that faults are not always stable in terms of rigid faults, but they can be stabilized by the appearance of kink bands or changes in the volume of each fault. This method allows for a quick estimate of the likely site of production for any fault and the strain direction of the surrounding rock and examines the kinetic model used to interpret the field data.
