摘　　要：为了刻画海拉尔－塔木察格盆地的构造演化过程，通过地震剖面分析和构造沉降中心迁移研究，在海拉尔－塔木察格盆地识别出5个构造层序界面和5个构造层，并从盆地的建造和改造角度划分出5个形成期和4个改造期。5个形成期为初始张裂期、断陷期、断坳期、坳陷期和萎缩期；4个改造期为塔木兰沟组末伸展翘倾期、铜钵庙末张扭变形期、伊敏组末张扭变形期和青元岗末反转变形期。研究认为，海拉尔－塔木察格盆地的发育具有建造与改造交互作用的特点并贯穿于盆地演化的全过程。Based on the seismic profile analysis and the research of tectonic subsidence center migration, five structural sequence interfaces and five structural layers were identified in Harlaer-Tamtsag Basin, which was divided into five generation stages and four reconstruction stages from the perspective of construction and reconstruction of basin. The five generation stages include initial tensional fracture stage, fault depression stage, fault sag stage, sag stage and atrophy stage. The four reconstruction stages include the extending and tilting stage during the late of Tamulangou Formation, the twisting and deforming stage during the late of Tongbomiao Formation, the twisting and deforming stage during the late of Yimin Formation and the reversing and deforming stage during Qingyuangang Formation. The research indicates that Hailaer-Tamtsag Basin has the characteristic of intersection of construction and reconstruction, and this characteristic is presented through the whole evolution process.
