| 摘 要： | 西藏北喜马拉雅地层分区石炭纪仅发育杜内期一维宪期沉积，时间跨度约30Ma，含亚里组与纳兴组两个岩石地层单位。据吉隆沟地层的特征可识别出潮坪、三角洲及浅海陆棚等沉积相。由层序界面性质与地层结构特征划分为2个Ⅰ型层序、7个Ⅱ型层序、2个层序组，属1个超层序。多数层序仅由海侵体系域(TST)和高水位体系域(HST)两部分组成。

| Abstract: | The Toumaisian and Visean deposits with a timespan of about 30 Ma developed in the Carboniferous strata in the Northern Himalaya stratigraphic subprovince in Xizang consist of two lithostratigraphic units: Yali and Naxing Formations, in which the tidal-flat, delta and shallow-marine shelf facies may be recognized. These stratigraphic sequences are involved in one supersequence, and consist of two I type sequences, seven II type (sequences) and two sequence sets, most of which are composed of the transgressive systems tract (TST) and highstand systems tract (HST). |
