摘要: 通过东昆仑马尔争地区早中二叠世生物礁地层剖面的深入研究, 详细阐述了东昆仑马尔争早中二叠世生物礁的基本特征、生物礁的演化和层序地层, 根据岩石组合特征、生物群落及海平面变化划分了12个造礁旋回, 归纳出5个三级层序, 并将东昆仑早中二叠世生物礁与扬子地台的二叠纪生物礁进行比较研究, 提出了造山带活动大陆边缘生物礁发育的基本规律.Abstract: The paper discusses the nature and evolution of reef based on the study of the Early-Middle Permian reef section in Maerzheng, eastern Kunlun and the sequence stratigraphy of the reef. The reef can be divided into 12 reef-building cycles, including 5 third class sequences, on the basis of rock features, biocommunities and sea level changes. Moreover, it puts forward the basic rule of reef development on the continental margin in comparison with those reefs of Early-Middle Permian in eastern Kunlun and in the Yangtz platform.
