【摘要】 南秦岭新生代安康月河盆地是北西向石泉—安康—竹山—房县左旋走滑断裂构造带西北端弯月状拉分盆地。论述了该盆地的边界断裂、盆地结构和三代盆地发育演化特征 ,估算了盆地最大扩张量 (1.4 5km)和主控边界断裂的走滑位错量 (2 .9km) ,分析了盆地主要储能结构与地震的关系。更多还原

【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.更多还原
