| Abstract: | Mylonite,cataclasite and especially fault rocks subjected to both mylonitization and cata-clasis widely developed along the Kangding-Moxi fault zone.A mylonite zone has formed as a result of ductile shearing in early stage.In later stage brittle fracturing has occurred along this mylonite zone,accompanied by the formation of the present Kangding-Moxi fault zone.Later on,ductile shearing and multiperiods of brittle fracturing occurred along the fault zone.Differential stress magnitude during the early faulting process was 50 MPa,as determined by using microstructural piezometer,while that for the late stage was 30 MPa.The activity of the fault zone tends to be weaker,i.e.from high to low stress level. |
