摘要: 1994 年在三塘湖盆地晚二叠世地层中首次发现了多毛类(Acerrotrupa sp.)、软舌螺(Hyolithes sp.)等。此套地层的成因与海洋有关。综合古生物、地球化学、沉积等特征认为本区晚二叠世为近海陆缘湖泊沉积环境。这为研究新疆北部晚古生代沉积环境、海退时间及方向提供了新的信息。

Abstract: Acerrotrupa and Hyolithes etc.were discovered for the first time in Upper Permian of Santanghu basin in 1994.After studying Paleontology, geochemistry and sedimentology, it is considered that the sedimentary environment of study area is offshore pericontinental lake in Late Permian.These offered new information for studying sedimentary environment, regression time and direction in Late Paleozoic in northern Xinjiang.
