摘　　要：新疆温泉下石炭统阿克沙克组为一套浅海相碎屑岩及碳酸盐岩建造,以细碎屑岩为主,含丰富动植物化石.通过对该套地层基本层序调查,划分出Ⅷ类副层序,建立了地层剖面结构.不同发展演化时期该区表现出不同的岩性、岩相特征,从下至上沉积环境由浅海陆棚→潮坪相→滨浅海相→三角洲相发展演化,与区域早石炭世晚期盆地发展演化一致.The Lower Carboniferous Arksak Formation clastic rock and carbonate formation, dominated in fine in the Wenquan area of Xinjiang is a set of neritic facies clastic rock,bearing abundant fossil. The survey of basic strata sequence of the formation indicate that the formation had various characteristics of lithology and lithofacies in different period of evolution and development, in generally it has a feature of slow sedimentary. From low to up the sedimentary environment changed from neritic shelf, tidal flat facies,coastal facies to delta facies,which coincided with regional basin evolution in late period of early carboniferous.
