Abstract:

This paper analyzes the activity characteristics of Meitai fault in west of Fushan Depression with the reference of
drill/logging and 3D seismic data,on the basis of interpreted seismic results,and by fault activity ratio analysis methods. Meitai
fault started to develop in E2ls2. Its activity was stronger in E2ls2 and E2ls1,thereafter the activity gradually decreased. In space,
the site with the greatest activity intensity migrated with the time passing by,while fault activity intensity differed significantly
in different parts of the study area. Generally speaking,the intensity of fault activity changed in a way of dying down from the
middle to the two flanks. We made a preliminary study on the fault controlling effect on basin settlement and sedimentary system
types with the combination of basin sedimentation rate and analysis of sedimentary system types and discussed the controlling
effect of fault activity on the deposition of sedimentation and sedimentary facies distribution.

Key words: fault activity, basin settlement, Meitai fault, sedimentary facies, Fushan Depression
