| 摘 要： | 大连金州地区震旦纪、早寒武世地层发育。本区该套地层可划分为震旦纪辽南超层序和早寒武世满家滩超层序，在其内部又可进一步划分为南关岭层序、棋盘磨层序、陆海层序、葛屯层序、大林子层序和草坨子层序六个层序地层单位。各层序之间均为不整合，其类型包括陆上暴露带、海岸暴露带及海侵面。每个层序仅由海侵体系域和高水位体系域组成。前者为退积地层结构，后者为进积地层，而中间饥饿段却表现为以加积为主，所有变化都与相对海平面及全球海平面变化有关。在此基础上，建立了区域地层格架，指出了本区该时期沉积范围主要在台地之内部（中陆架），局部发育深水陆棚盆地。

| Abstract: | Sinian system and Lower Cambrian series in Jinzhou area,Daian,can be divied intoSinian Liaonan ultra-sequence and Early Cambrian Manjiatan ultra-sequence,and can be sub-divided into Nanguanling ,Qipanmo, Luhai,Getun,Dalinzi and Caotuozi sequences.The rela-tionship between every two sequences were unconformable, which the types included subaeri-al exposure belt,coastal exposure belt and marine invasion plane. Each sequence was consist-ed of marine invasion and high water level system domains,which the former was ret-rograding strata, the latter was prograding strata, but starvated member between them wasmainly accretion strata,all the changing was related with relative sea level and global sea lev-el,On the base of above features,the paper set up a regional stratigraphic framework and in-dicated the sedimentary scope then mainly was within the plateform which partly developeddeep-water continental shelf basins. |
