摘　　要：对准噶尔盆地晚白垩世地层的岩性特征、沉积环境、厚度变化及分布规律进行了讨论.这套红色地层在不同时期、不同地段分布范围和沉积厚度变化较大,岩性单一,环境单调,生物化石较贫乏,但介形类化石很典型,表现出晚白垩世化石组合特征,建立了3个介形类化石组合,为准噶尔盆地晚白垩世地层划分与对比起到了重要作用。This study focuses on the lithostratigraphy and paleoenvironment reconstruction of the Upper Cretaceous in the Junggar Basin, which is characterized by a succession of red beds. The Upper Cretaceous in the Junggar Basin is regionally variable in thickness and poor in fossils. However, ostracod fossils from these rocks are characteristic of Late Cretaceous. Three ostracod assemblage zones have been recognized. These assemblage zones offer a biostratigraphic tool to correlation of Upper Cretaceous successions in the Junggar Basin.
