| 摘 要： | 上二叠统记录着地质历史上最大的生物灭绝事件和最深刻的环境变化。长期以来由于世界各主要沉积区晚二叠世地层的同期性未能确定 ,对这一事件及其过程难以全面了解。随着乐平统成为全球上二叠统的标准 ,我们选用若干生物地层、磁性地层和层序地层等的联接点 ,提出乐平世地层世界对比的试用方案

| Abstract: | The Upper Permian recorded the greatest mass extinction and the most dramatic environmental changes in geologic history. Understanding the process of these events has long been handicapped by the uncertainty of their synchronity of Late Permian sequences in major depositional regions. With the Lopingian Series as the global standard for the Upper Permian and a set of bio-, magneto- and sequence stratigraphic tie points, a global correlation of Lopingian rocks at stage-level is tentatively suggested. |
