| Abstract: | The Cenozoic Yuehe(in Ankang) basin in South Qinling area is a pull apart basin like crescent moon at the northwestern and section of NW Shiquan Ankang Zhushan Fangxian left leteral fault zone.The boundary faults,basin structure, as well as basin development evolution charactoristics of the basin in three eras are discussed,the maxium spreading value(1.45 km) and the strike slip dislocation value of principal boundary fault(2.9 km) are estimated and the relationship of main energy storing structure of this basin to earthquake is analyzed as well. |
