NAPPE STRUCTURE IN FUJIAN PROVINCE

Surface and deep geophysical data analysis has proved the existance of nappe structures in Fujian Province.Accordingto different shapes,they can be divided into 3 types: the eastern thrust nappe belt,the central thrust fold belt and the western compressive nappe belt.Regional tectonic analysis indicates that,nappe structures in the Fujian Province were generated during the Indosinian epoch,propagated mainly during the early Yanshan epoch and decreased in the late Yanshan epoch.The nappe movement is from northwest to southeast.The formation of nappe is related to the tectonic movement of circum-Pacific continental active belt.
