Abstract

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.

摘要： 用测汞法对隐伏断层活动性进行分段,并就汞的地球化学标志进行了初步探讨。研究表明,当隐伏断层的上断点埋深较浅(几米～几十米),且该断层上各测线的汞含量背景均值接近时,用测汞法进行断层活动性分段可能是有效的。
