LATEST PERMINA TO EARLY TRIASSIC LITHOSTRATIGRAPHIC FRAMEWORK IN PUQI,HUBEI

摘要: 蒲圻凤凰山、荆泉山两地晚二叠世晚期至早三叠世地层划分为三个层序：晚二叠世晚期至早三叠世早期的Ⅱ型层序、早三叠世中期的Ｉ型层序和早三叠世晚期的Ⅲ型层序。该层序划分可与Ｍａｒｚｏｌｆ（１９９３）在ｃｏｌｏｒａｄｏＧｒｅａｔＢａｓｉｎ同期地层的层序划分对比相当。还讨论了副层序组合堆积型式、Ｉ型或Ⅱ型层序界面及凝缩段的概念理解和实践操作等问题。Abstract: The late Late Permian to Early Triassic strata in Fenghuang Mountain and JingquanMountain,Puqi,Hubei,may be divided into three sequences :sequence II of late Late Permian toearly Early Triassic age,sequence I of middle Early Triassic age and sequence II of late EarlyTriassic age. The sequence division is in agreement with that of the contemporaneous strata inthe Great Basin,Colorado,United States,made by Marzolf in 1993.
