摘　　要：研究认为,南黄海北部盆地断裂体系及盆地隆凹格局指示盆地具有明显的右旋扭动成盆性质;盆地断裂体系可以分为一级控盆断裂、二级控凹断裂及三级凹陷内伴生断裂3个级别,盆地内凹陷具单断箕状断陷、双断斜交断陷、双断平行断陷3种类型;先存近EW向印支期逆冲断裂负反转、燕山—喜山期NE向具走滑性质的千里岩控盆断裂及其派生的NEE向张扭断裂共同控制了南黄海北部盆地断裂体系展布特征及其独特的具多种凹陷结构类型、发育规模不等、分割性较强的盆地隆凹格局。The fault system of the northern South Yellow Sea Basin and the uplifting and depression pattern of the basin suggest a clear dextral twist movement.The fault system can be classified into three levels：basin-controlling fault,sag-controlling fault and derived fault within a sag.There are three types of sag in the basin：single-faulted graben,oblique double-faulted rift and parallel doublefaulted rift.The original inverse thrust faults nearly in EW direction,was formed in the Indosinian stage,and the Qianliyan fault in NE and its derived faults formed later in the Yanshan Himalayan period.All of the faults jointly controlled the distribution pattern of the fault system and the uplift-depression of the northern South Yellow Sea Basin.
