摘要(Abstract)：

黄河口凹陷新生代断裂复杂多样,岩浆活动频繁。利用三维地震资料,根据断裂体系特征、构造演化分析、地层厚度变化及钻井资料等,研究黄河口凹陷南斜坡新生代断裂构造特征及演化规律,分析断裂体系在古新世—早始新世断陷期、晚始新世—渐新世强走滑与强拉张期、新近纪走滑与热沉降期三个阶段的区域应力背景及演化特征。结果表明:研究区断裂体系划分为走滑断裂、拉张—走滑断裂和走滑—拉张断裂等三种断裂类型,以及"阶梯状""负花状""雁列式"和"复合花状"等四种断裂组合类型,并具有"三元"构造层结构特征;岩浆活动规律与断裂演化史具有同步性,断裂体系演化规律控制岩浆活动的时空差异性。该研究结果对复杂构造区断裂解释和岩浆活动模式建立具有参考意义。
