摘　　要：分析了东营凹陷纯东区域的构造背景及基底断裂发育特征,结果表明:断裂是该区构造的主要控制因素;研究区内发育基底断裂系统和盖层断裂系统;在这两大断裂系统的共同作用下,形成了本区域南北分带、东西分块的构造格局;这些断裂构成了多种组合模式;纯东地区的断裂活动遵循早期强烈同沉积,早中期多期同沉积后期反转,长期多期同沉积晚期反转的3种发育模式.By the analysis of the regional structure background and the development characters of basement faults, the results can be concluded as following :faults are the main controlling factors of the structure; two fault systems exist in the research area: one is the fundus fault system, the other is cap rock fault system. Under the combined effect of the above two systems, the structure pattern developed in strip type through N-S while in block type along W-S. These faults display in many combination modes; the structure activities in Chundong area can be divided into three modes: forceful syndeposit in forepart , the reverse in late stage of the early- metaphase formed multiple syndeposit and the reverse in late stage of the perennial-multiple formed syndeposit.
