二叠纪地层小组委员会正在集中努力确定西苏拉系的其余三个全球地球同步卫星，并完善二叠纪时间表，以便进行全球对比，包括陆地对比。本文根据新的生物地层学、地球化学和年代学资料，简要介绍了二叠纪时间尺度发展的最新进展。根据南乌拉尔和华南地区最新的U-Pb年龄，二叠纪的年龄为298.9 ~ 252.17Ma。西苏拉纪、瓜达卢佩纪和洛平纪的持续时间分别为2660万年、1250万年和7630万年。
The Subcommission on Permian Stratigraphy is concentrating its efforts to establish the remaining three GSSPs in the Cisuralian as well as refining the Permian timescale for global correlation, including into the terrestrial realm. In this paper, we provide a brief overview on recent progress of Permian timescale development based on new biostratigraphic, geochemical and geochronologic data. The Permian Period was from 298.9 Ma to 252.17 Ma based on the latest U-Pb ages in the southern Urals and South China. The Cisuralian, Guadalupian and Lopingian have durations of 26.6 Myr, 12.5 Myr and 7.63 Myr, respectively.
