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。

These offered new information for studying sedimentary environment , regression time and direction in Late Paleozoic in northern Xinjiang .

从相分析着手，重点剖析京山、崇阳两条岩相剖面，系统地研究了岩石、古生物、地球化学组分及分布规律。

Starting with the fades analysis and emphatically dissecting two field sections of Jinshan and Chongyang On the Middle Yangtze Permian Carbonate Platform , a carbonate facies model has been established based on systemically studying its rock , palaeobiology and geochemistry .

在~（14）C、古地磁、氨基酸测定、微体古生物，矿物和化学元素测试分析的基础上，划分了本区的沉积层及年代。

Based on analyses by 14C , paleomagnetism , amino acid , micropaleontology , minerals and geochemistry , the stratification and their depositional period are determined .
