| 摘 要： | 阿荣旗太古山西北部陆相盆地光华组一段沉积岩非常发育，为一套正常火山碎屑沉积岩组合.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，本区光华组一段沉积岩自下而上可划分为1个Ⅱ级层序，2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，为大兴安岭地区中生代陆相盆地层序地层的研究提供参考.

| Abstract: | The first member of Guanghua formation,developed in Taigu Mountain area,is a set of normal pyroclastic sedimentary rocks.Based on the rock association,fabrics,vertical variation and the changes of sedimentary environment of the area,one second-order sequence can be recognized,including 2 third-order sequences with 7 fourth-order sequences.The study on the sequence stratigraphy may support the research on the sequence strata of Mesozoic continental basin in Daxinganling region. |
