【Abstract】 The Fangxian basin of Cenozoic Era of South Qinling is a pull-apart basin at the southeastern end of the Ankang-Zhushan-Fangxian NW-trending left-lateral strike-slip fault zone.The boundary faults,basin structure and development and evolution features in three periods of this basin are described.The maximum expansion of this basin is estimated as 2.73 km,the strike-sliping dislocation of its principal boundary fault is 3.57 km and the relation of main energy-reserving structure of the basin with the earthquakes is analyzed as well.更多还原
