银根-额济纳旗盆地石炭-二叠系是我国近几年油气勘探的热点区域之一。本文以野外地质调查为基础,对盆地东部石炭-二叠系阿木山组开展了露头层序地层学研究。在区内阿木山组识别出构造体制转换面、削截及上超面及准层序叠置样式转换面三种层序界面,划分出三个三级层序,讨论了层序特征及层序内沉积相的演化。并初步探讨了在海相裂谷盆地及造山带地区中开展层序地层学研究的方法、步骤及注意事项。 The Yingen-Ejinaqi Carboniferous-Permian is one of the hot spots for oil and gas exploration in China in recent years. Based on the field geological survey, this paper studies the outcrop sequence stratigraphy of the Amunshan Formation in the Carboniferous-Permian of the eastern basin. In the area, the Amunshan Formation identified three sequence interfaces of structural system transition plane, truncated and super-super plane and quasi-sequence superimposed pattern transition plane, divided three third-level sequences and discussed sequence features and layers Evolution of sedimentary facies in the sequence. The methods, steps and precautions of studying sequence stratigraphy in marine rift basins and orogenic belts are also discussed.
