Title: Upper Cretaceous Sporopollen Assemblage and Significance of Ziniquanzi Formation in Southern Margin of Junggar Basin
Abstract: A sporopollen assemblage Schizaeoisporites-Classopollis-Yenjiapollis discovered from the mid-lower part of Ziniquanzi formation in southern margin of Junggar basin is reported. According to the characteristics and the correlation results, the geologic era of this sporopollen assemblage is dated as Mid-Late stage (or Early Senonian) of Late Cretaceous. This discovery supplies a gap for absence of sporopollen assemblage of Late Cretaceous in northern Xinjiang, providing significant data or proof for the studies of Late Cretaceous micropaleo-flora in Junggar basin and even in China. From the particularity of this sporopollen assemblage, northern Xinjiang should be classified as arid palynofloral region in northwestern China.
