If a fault has a verticalfault plane. How do we determine its hanging wall and footwall?
若一断层的断层面是直立的，我们怎么去确定它的上盘和下盘呢？

Based on this principle, the new function expressions of 2-d anomalies due to sloping thin dikes, geologic contact and verticalfault have been deduced, respectively.
基于这一原理，本文就二度岩脉、接触带、垂直断层磁异常的反问题导出其表达式。

Based on the data of cross—fault survey in the study area, the annual rates of verticalfault motions in related fault zones were calculated and the behaviours of fault motions were analyzed.
