吉辽徐淮地区新元古代形成时代及地层划分对比研究

Constrast and Study on Forming Stage of Neoproterozoic and Stratigraphic Division in Xuzhou Huaihe River Region Jilin Province and Liaoning Province

摘要:

吉辽徐淮地区新元古代地层划分对比目前没有统一的方案。许多研究者从Sr同位素、C同位素、地质事件、古地磁和古生物等方面对吉辽徐淮地区新元古代地层的形成时代和地层对比进行研究，并提出了各自的地层划分方案，该文探讨了寻找标志性的生物化石，采集更多Sr，C的同位素数据，开展区域性的地质调查，进行地层划分对比的重要性，同时指出这也是今后研究的重点方向。

Abstract:

The univeral division of Neoproterozoic stratigraphy in Xuzhou, Huaihe river region, Jilin province and Liaoning province has not been achieved. According to the evidences of the isotopes of Sr and C, various stratigraphic division programs were put foward. In this paper, the significance of finding landmark fossils, collecting isotope data of Sr, C data, carrying out regional geological survey, and constrasting and dividing of strata were discussed. All of these can be regarded as the focus of furthur researches directions in the future.
