Abstract: The fluid flow upward along fault zone may bring some environmental changes,such as the exceptional high temperature and pressure near fault,the petrology and mineralogy abnormity,and the changes of geophysical and geochemical characteristics of fluid itself.All information about these changes and abnormities resulted from fluid flow can be taken as the powerful indications of fluid flow along fault zones.The analysis on macroscopic phenomena and microcosmic test provide some information to confirm the evidences of fluid flow along fault zones.

Key words: fault zone, fluid flow, abnormal temperature, abnormal pressure, petrology and mineralogy, biological marker, fluid inclusion

摘要： 运用宏观分析与显微测试等手段,对断裂带周围介质及流体本身进行了分析,识别出能够反映流体沿断裂带活动的信息.流体沿断裂带向上运移时会使周围介质及其自身发生变化,如:断层附近的温度、压力异常及围岩出现的岩石矿物学异常通常与流体活动有关,流体本身的性质也因在断层中运移而发生改变.这些流体活动带来的异常及变化就是流体沿断裂带活动的有力证据.
