| 摘 要： | 浙江长兴煤山的 D剖面经多年研究 ,已成为二叠系长兴阶的单位层型和二叠系 -三叠系全球界线层型 ,并被推荐为吴家坪阶 -长兴阶全球界线层型的候选剖面 ,因该剖面上龙潭组地层出露较少 ,以致国内对长兴组与龙潭组的接触关系存有不同意见 ,给层型剖面的建立带来不利影响。在清理和研究了 D剖面西侧 30 0 m处 C剖面的吴家坪阶 -长兴阶界线层段后 ,证实了煤山地区龙潭组与长兴组为整合接触 ,对相关化石的地层分布也获得进一步的认识

| Abstract: | Section D at Meishan, Changxing in Zhejiang Province has been studied in detail for many years and has been accepted as the stratotype section for the GSSP of the Permian Triassic boundary. It has also been proposed as the candidate section for the GSSP of the base of the Changhsingian Stage. However, the short exposure of the Longtan Formation at that section has resulted dispute regarding the basal contact relationship between the Longtan and Changxing formations, which became a negative influence on the establishment of the GSSP at Meishan. In order to get more information, Meishan Section C, about 300 metres to the west was excavated. The exposure of the boundary strata of the Changxing and Longtan formations provides strong evidence for a comformable succession. The stratigraphic distribution of corresponding fossils gives further understanding of the stratigraphic correlation of this interval. |
