| Abstract: | By finely handling a batch of gravity difference data in the northern segment of the Red River fault zone,we found the temporal variation of these gravity differences in the period from 1985 to 2006.The research results show that: 1)The fault activity is cyclical by alternatelly being strong and weak,and in the two different processes both of the extrusion degree and time duration are different.2) The fault activity has obviously segmental character that the fault activities in Jianchuan-Xiaguan are basical... |
