摘　　要：千里岩隆起位于南黄海的最北部,是一个长期裸露的基底隆起区。通过对南黄海重力异常的区域分析和异常分区以及与苏鲁隆起的地质对比研究,认为两者具有同一地质成因,前者是后者的东向延伸,皆成因于印支期华北板块和与扬子板块的碰撞。早白垩世,后期太平洋板块西向俯冲使千里岩断裂带反转变化为同生正断层。Qianliyan Uplift to the north of the Southern Yellow Sea is uplifted basement which exposed for a long time.The regional analysis and division of the gravity anomaly in the South Yellow Sea and the comparative study of the petrologic geochemistry between Qianliyan Uplift and Sulu Uplift are researched,these illustrated that the geological genesis of them is the same;the former is the extension of latter in marine.Both formed due to collide of the north China plate and Yangtze plate in Indo-Chinese Epoch.The Qianliyan fault becomes the syngenetic normal fault by the westward subduction of Pacific plate in Early Cretaceous.
