    ABOUT QUOTING OF DATING IN FAULTS ACTIVITY APPRAISAL

    • The faults activity appraisal is a foundation for study of regional tectonic stability because it directly affects the safety of a hydraulic engineering structure against seismic activity.Dating of fault gouge is now a common method for evaluation of faults activity,one of the quantitative methods.However,different dating methods tend to give different results even for the same fault gouge sample,which has caused concerns on the reliability of fault activity appraisal.In this paper,the author discusses some of problems in adduction of dating information of the fault gouge in hydropower projects and suggests methods for resolving the problems.A case study on the activity of Mabian-Yanjin,Lianfeng and Jinyang faults of the Xiluodu hydroelectric project is presented to demonstrate methods suggested by the author.
