| 摘 要： | 依据钻孔及露头资料,对黑龙江东部鸡西盆地进行了构造层序划分及研究,共划分了1个Ⅰ级、2个Ⅱ级、5个Ⅲ级构造层序,在此基础上讨论了鸡西盆地动力学演化机制,证实鸡西盆地主要由敦密断裂在白垩纪左旋走滑拉分而成.纵向上表现为两个构造演化阶段:早白垩世早中期表现为断陷盆地特点,控制了鸡西群含煤层序的生长和发育;早白垩世晚期-晚白垩世早期表现为坳陷盆地特征,控制了桦山群红层的生长、发育.该盆地的层序划分及动力学分析对黑龙江东部白垩纪地层对比、构造作用及成矿作用的分析提供了重要依据. |

| Abstract: | According to bore holes and exposures,the authors studied the structure sequences of the Jixi basin in Eastern Heilongjiang Province.With classification of tectonic sequence,the authors discussed the dynamics evolution of Jixi basin,suggesting that the Jixi basin was formed by pull apart of left-handed strike-slip related to the Dunmi rift zone in the Cretaceous.Longitudinal expression include two tectonic evolution periods: block-faulting stage in early-middle stage of the Early Cretaceous(expressed,) which was controlled by the growth of coal-bearing sequence in Jixi Group;down-warping(period) in late stage of the Early Cretaceous-early stage of Late Cretaceous,which was controlled by the growth of red sequence in Huashan Group.The sequence classification and dynamic analysis of this basin provide an important evidence to the stratigraphic correlation,tectonic analysis and minerogenesis. |
