用K-Ar测年技术确定了塔里木盆地库车河剖面上二叠统二次侵入岩的形成年龄为227.6±3.34Ma,还使用ESR技术测试了侵入岩和烧变岩中石英氧空位的相对浓度。根据库车河二次侵入岩的K-Ar年龄,石英氧空位的相对浓度和剂量率,估算出上三叠统塔里齐克组烧变岩的形成年龄为3.26±0.3Ma,中侏罗统克孜努尔组烧变岩的形成年龄为2.33±0.2Ma。此外,还讨论了烧变岩形成年龄的可靠性问题。
The formation age of Permian secondary intrusive rocks on the section of the Kuqa River in the Tarim Basin was determined to be 227.6 ± 3.34 Ma by K-Ar dating technique. ESR techniques were also used to test quartz oxygen in intrusive rocks and sinter rocks The relative concentration of vacancies. According to the K-Ar age, the relative concentration of oxygen vacancies and the dose rate of quartz in the secondary Kuqahe intrusive rock, the age of formation of the Tarimianke Formation in the Upper Triassic is estimated to be 3.26 ± 0.3Ma, The age of formation of sinter rock in the Middle Jurassic Kitazur Formation is 2.33 ± 0.2Ma. In addition, the reliability of the formation age of burnt rock is also discussed.
