Abstract: In this paper,some examples of segmentation of active hidden fault are introduced by using mercury measurement as well as a preliminary discussion on mercury geochemical indicator for different segmentation of active hidden faults.If the buried depth of a hidden fault is relatively shallow (severial to tens of meters) and the average background value of mercury for the traverses along the hidden fault is the same on the whole,it is possibly effective to make segmetation of the active hidden fault by using mercury measurement.Meantime some questions related to segmeatation of active fault are discussed as well.
