天然断层中普遍存在含有粘土矿物的断层泥，大量的实验研究和野外观察证实，不同应变速率的变形作用在断层泥中留下了特殊的显微构造特征（如褶皱、眼球状构造和膝折等）。因此，我们可以根据断层泥的变形特征，来推测变形时断层的滑动方式和次序。尽管这一方面的研究还处于探索阶段，但它可能将成为研究活断层的一个新途径。 There are ubiquitous fault muds containing clay minerals in natural faults. A large number of experimental studies and field observations confirm that deformations at different strain rates leave special microstructural features (such as folds, eyeballs, and kinks) in the fault mud ). Therefore, based on the deformation characteristics of fault mud, we can infer the slip pattern and sequence of faults during deformation. Although research in this area is still in the exploratory stage, it may be a new way to study the active fault.
