摘要

南秦岭新生代房县盆地是北西向安康 竹山 房县左旋走滑断裂构造带东南端拉分盆地。论述了该盆地边界断裂、盆地结构和 3期盆地发育演化特征。估算盆地的最大扩张量为 2 .73km ,主控边界断裂的走滑位错量为3.5 7km ,并分析了盆地主要储能结构与地震的关系。
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.
