| 摘 要： | 东北地区前中生代构造演化可大致分为如下阶段：（１）中、新元古代阶段；（２）早古生代加里东阶段；（３）泥盆纪—早石炭世早华力西阶段；（４）晚石炭世—三叠纪晚华力西—印支阶段。多旋回构造演化使该区形成由多期褶皱带和多中间或边缘地块组成的“镶嵌构造区”，并为晚中生代大型含油气盆地的发育奠定了基础。

| 关 键 词： | 东北地区，构造演化，镶嵌构造区，中生代盆地 |
PRE MESOZOIC TECTONIC EVOLUTION AND ITS RELATION WITH DEVELOPMENT OF LATE MESOZOIC BASINS IN NORTHEASTERN CHINA |
| |
| Abstract: | In Northeastern China, four periods are divided for the tectonic evolution of pre Mesozoic as follows: (1) Meso Neo Proterozoic period; (2) Caledonian period,Early Palaeozoic; (3) Early Variscan period, Devonian Early Carboniferous; (4) Late Variscan Indosinian period, Late Carboniferous Triassic.Here formed the ‘mosaic structural area’ made of polygenetic foldbelts and poly median or marginal massif because of polycyclic tectonic evolution, which provided basis for the development of large scale Late Mesozoic oil and gas basins. |
