| 摘 要： | 据陆相层序地层学原理及野外露头层序地层学方法,对新疆和田地区桑株、杜瓦、皮牙曼、阿其克等剖面的二叠—下三叠统进行层序界面识别,建立了和田地区层序地层格架.研究表明,该区二叠—下三叠统共划分为5个Ⅲ级层序及12个体系域.研究区在不同时期共发育5种沉积体系类型,包括冲积扇体系、河流沉积体系、湖泊沉积体系、三角洲体系及扇三角洲体系,指出该区层序演化中有利的烃源层、储集层和盖层及组合.

| Abstract: | According to principles of continental sequence stratigraphy and outcrop sequence stratigraphy,we have identified the sequence interface of Sangzhu,Duwa,Piyaman,Aqike etc.in Hetian area,Xinjiang province,established the sequence stratigraphic framework of Hetian area during this time,study shows that Permian-Lower Triassic of this area can be divided into five third-order sequences and twelve systems tracts.The depositional system of the study area has developed five types,including alluvial fan system,fluv... |
