| 摘 要： | 扎兰屯哈拉口子北山上石炭统-下二叠统格根敖包组一段沉积岩非常发育，为一套正常陆源碎屑沉积岩组合.根据岩石组合特征、组构、岩层垂向变化规律、沉积环境变化等分析，本区格根敖包组一段沉积岩自下而上可划分为1个Ⅱ级层序，3个Ⅲ级层序及7个Ⅳ级层序.对其进行层序地层学等方面的研究，为大兴安岭地区晚古生代沉积盆地层序地层的研究提供一定的参考.

| Abstract: | A set of normal terrigenous clastic sedimentary rocks of the first member of Gegenaobao Formation, Upper Carboniferous-Lower Permian, is well developed in Zhalatun area, Inner Mongolia. Base on the analysis of the rock assemblage, composition, vertical variation of strata and sedimentary environment change, the sedimentary rocks of Gegenaobao Formation may be subdivided into one Grade Ⅱ sequence, including three Grade Ⅲ sequences and seven Grade IV sequences. Study on the sequence stratigraphy provides a valuable reference for the Late Paleozoic sedimentary basin formation in Daxinganling region. |
