| 摘 要： | 通过对塔里木盆地西南缘上震旦统克孜苏胡木组详细的岩石学特征、沉积相类型、组合及沉积层序研究认为，研究区克孜苏胡木组为一典型的有障壁海岸沉积体系，可划分出滨外陆棚、障壁岛和潮坪3个亚相；障壁岛海滩体系在研究区发育近滨、前滨微相而后滨砂丘不发育；潮坪沉积体系包括潮上带、潮闻带和潮下带3个微相；沉积演化和沉积模式研究表明其属海退模式。 |
| 关 键 词： | 塔里木盆地 震旦系 克孜苏胡木组 沉积环境 潮坪 障壁岛 |

| Abstract: | A detail study of petrologic characteristics, type of sedimentary facies, its assemblage and sedimentary sequence in the upper Sinian Kezisuhumu Formation in the southwest margin of Tarim Basin indicates that Kezsisuhumu Formation is a typical beach-barrier sedimentary system, it can be divided into 3 subfacies such as barrier island, tidal flat and offshore shelf. In the studied area, nearshore and offshore microfacies are developed while backshore rigs are not grown in the beach-barrier coast system. The tidal plat deposition system includes 3 microfacies, such as supralittoral zone, intertidal zone and subtidal zone. The study on sedimentary evolution and sedimentary pattern indicate that it belongs to regression pattern. |
| Keywords: | Tarim Basin Sinian Kezisuhumu Formation sedimentary environment tidal flat barrier island |
