摘要

摘要: 通过对玉北地区皮山北2井奥陶系71个碳同位素样品分析结果的初步研究,首次在塔盆井下发现GICE碳同位素正漂移事件,将该区奥陶系的碳同位素特征划分为3个阶段:第1阶段为缓慢上升(鹰山组中下部);第2阶段为"零"值附近振荡(鹰山组上部至良里塔格组中下部);第3阶段为GICE事件(良里塔格组的上部).该区奥陶系碳同位素表现出自下而上由负值向正值整体缓慢升高,在上奥陶统良里塔格组上部突变为正值的演化特征.

Abstract: According to the analyses of 71 carbon isotope samples from Ordovician in the well Pishanbei2 in the Yubei area, GICE event was discovered for the first time under well in the Tarim Basin. The carbon isotope features of Ordovician were classified into three periods as followed. In the first period, it gradually increased in the lower and middle Yingshan Formation. In the second period, it varied nearby zero value from the upper Yingshan Formation to the lower and middle Lianglitag Formation. In the third period, the GICE event took place in the upper Lianglitag Formation. The carbon isotope values slowly raise from negative to positive in Ordovician, and broke into positive in the upper Lianglitag Formation in the study area.
