摘要(Abstract)：

为系统揭示塔里木盆地塔中隆起中北部地区断裂构造特征及其成因演化，通过对该区大连片三维地震工区精细构造解析和相干体等分析，并结合区域动力背景，系统论述了该区的断裂构造类型、几何学特征、差异活动机制及其构造演化过程。研究结果表明，塔中隆起中北部发育了4类7期断裂构造，其中逆冲断裂和走滑断裂尤其发育。平面上北西向弧形逆冲断裂与北东向、北西向及南北向走滑断裂相互交切与耦合；垂向上断裂分层差异活动特征明显，下奥陶统及其以下地层，断裂发育数量多且以线形为主，中奥陶统-中下泥盆统多呈雁列式，上泥盆统-二叠系仅在塔中Ⅱ号断裂带、顺北5号断裂带西南端等地区发育少量断裂。研究区断裂活动受多期、多方向不同性质应力场所控制，经历了极其复杂的演化历史：加里东早期以塔中Ⅱ号断裂带等少量北倾正断层活动为主；加里东中期Ⅰ幕断裂活动强烈，表现为逆冲断裂与走滑断裂协同演化和相互耦合特征，走滑断裂对逆冲断裂的切割或限制作用明显；加里东中期Ⅲ幕断裂活动基本继承了加里东中期Ⅰ幕的构造格局，但在工区北部的顺北4号、5号等断裂带张扭性断裂活动特征显著；加里东晚期-海西早期，部分断裂发生继承性活动且张扭断裂发育范围进一步向南扩大；印支-燕山期，仅有少数断裂发生继承性活动；喜山期该区构造比较稳定，早期形成的复杂断裂构造进入深埋阶段。
