摘要
国际二叠纪地层分会已就二叠系的统和阶的划分、命名及其下界的层位达成统一意见,提出新的二叠系年代地层表,该表由3个最佳的区域性地层序列组成,即代表下二叠统的俄罗斯和哈萨克斯坦乌拉尔地区的乌拉尔统(Cisuralian Series),上二叠统下部和上部的美国西南部的瓜德鲁普统(Guadalupian series)和中国华南地区的乐平统(Lopingian Series)。新表为建立二叠系内部界线的全球层型及点位准备了工作方案,也为更精确地对比海相二叠纪地层提供了参照标准。
International agreement has been achieved on the names of series and stages into which the Permian System should be divided and on the levels for the basal boundaries of these subdivisions. This scheme incorporates three excellent reference successions: the Cisuralian Series of the Urals, the Guadalupian Series of the SW USA and the Lopingian Series of South China which represent the Lower Permian and the lower and upper series of the Upper Permian respectively. The scheme will serve as a working template for the Permian Subcommission in defining the GSSPs for intra-systemic boundaries and also enables us to correlate the Permian marine sequences worldwide in a higher resolution manner.
