乐平纪代表古生代的最后一个时代，并被与剧烈的环境变化有关的两次严重的生物群灭绝所包围。乐平纪持续了大约700万年，也被大规模的火山喷发所包围，峨眉山火山岩在底部，西伯利亚圈闭在顶部。最近积累了大量的数据，在本文中，我们试图在一个高分辨率的Lopingian（晚二叠世）时间尺度上总结这些发现，该时间尺度整合了目前可用的多种生物地层学，同位素化学地层学，地质年代学和磁性地层学数据。在中国南部，至少有13个牙形石带、多极性带和乐平阶的碳同位素波动，这些都为研究地球上最大的生物灭绝事件--晚二叠世间隔提供了必要的高分辨率标定。我们还提出了一个全球相关图表的海洋乐平系列。版权所有© 2010约翰威利父子有限公司.
The Lopingian represents the last epoch of the Palaeozoic Era and is bracketed by two severe biotic mass extinctions associated with dramatic environmental changes. The Lopingian Epoch lasted about 7 millions years and was also bracketed by large volcanic eruptions with the Emeishan volcanics at the base and the Siberian traps at the top. Considerable data have accumulated recently and in this paper we attempt to summarize these findings in a high‐resolution Lopingian (Late Permian) timescale that integrates currently available multiple biostratigraphic, isotope chemostratigraphic, geochronologic and magnetostratigraphic data. In South China at least 13 conodont zones, multiple polarity zones and large carbon isotope fluctuations in the Lopingian are recognized and provide the high‐resolution calibration that is essential to study this Late Permian interval characterized by Earth's largest biotic extinction. We also present a global correlation chart for the marine Lopingian Series. Copyright © 2010 John Wiley & Sons, Ltd.
