A fault is not a simple plane, but a belt composed by a series of breaking planes or secondary faults, which is contradict with the hypothesis of the theory of cross-fault lithology juxtaposition.
Based on the data of cross—fault survey in the study area, the annual rates of vertical fault motions in related fault zones were calculated and the behaviours of fault motions were analyzed.
