摘要: 塔里木板块西北缘石炭纪时期为一典型的被动大陆边缘 ,通过对本区石炭纪沉积层序及相对海平面变化研究 ,识别出不同类型的层序界面 (SB1,SB2 ) ,并据此划分了 4个二级沉积层序—超层序(Super sequence)和 8个三级沉积层序 (Sequence) ,且在区域上或全球范围内基本上可以对比。但由于所在大地构造位置不同 ,其沉积背景条件差异很大 ,因而在不同地区可以形成不同样式、不同数量的沉积层序 ,海平面变化表现形式也存在差别。

Abstract: The northwestern margin of Tarim plate was a typical passive continental margin during Carboniferous period. Based on the research of sedimentary sequences and relative sea level changes of the Carboniferous in the areas, the various types of sequences boundariesⅠ(SB 1) and Ⅱ(SB 2) can be identified, and then the Carboniferous strata can be subdivided into four two order sedimentary sequences or supersequences, or eight three order sedimentary sequences, which can be correlated briefly in regional and global areas. The mode and quantity of the sedimentary sequences and the change of sea level in different areas can be great different because of the great different tectonics and sedimentary settings.
