| 摘 要： | 对塔里木盆地奥陶系锶同位素分析表明，在早奥陶世海平面呈下降２，在中晚奥陶世海平面则持续上升并保持在高于奥陶纪平均海平面之上。氧，碳同位素及微量元素的分析结果均支持锶同位素的研究结论。研究表明，沉积层序中发育相应的沉积地球化学样式。

| Abstract: | The analysis of the w ( 87 Sr)/( 86 Sr) ratio of Ordovician shows that the sea level dropped in Early Ordovician,and then rose continuously and stayed above the average level in Middle and Late Ordovician in Tarim Basin.The study of oxygen and carbon isotopes and trace elements geochemistry draws the same conclusion as that of the study of the Sr isotope analysis.In brief,the sequence stratigraphy is correspondent with its sedimentary geochemistry style. |
