| 摘 要： | 对克百断裂下盘二叠系砂砾岩中碳酸盐胶结物的氧、碳稳定同位素的年代效应进行较正,对其组成特征进行研究.结果发现氧稳定同位素较轻,主要位于-16‰～10‰(PDB),而碳稳定同位素变化较大,大部分处于0-9‰(PDB),少量小于-15‰(PDB).经过分析计算,认为研究区砂砾岩中碳酸盐胶结物形成于早成岩晚期、70～90℃淡水环境中,这种结果与当时的构造背景、沉积环境、气候条件相符合. |
| 关 键 词： | 克百断裂 二叠系 砂砾岩 碳酸盐 稳定同位素 |

| Abstract: | After the proofreading of time effect of the carbon and oxygen stable isotopic of carbonme cementation in Permian rudite Of the footwall of Kebai-fault,its composition character is researched.The oxygen stable isotopic value (PDB)show light(-16～-10‰).while the carbon stable isotopic value(PDB)range is widely with mainly from 0 to 9‰ and few below -15‰.The carbonate cementation is produced in latter stage of early diagenesis and fresh water which paleotemperature is mostly from 70℃ to 90℃.Such environment is accord with the tectonic setting and deposit surround as well as climate condition. |
| Keywords: | Kebai-fault Permian Rudite Carbonate Stable isotopic |
