二叠系-三叠系界线全球层型剖面和点位置于浙江煤山D剖面第27层内Hindeodusparvus的首现面.第27层通常被视为均质的粉砂质灰岩,界线上下的沉积特征没有发生变化.深入研究界线层序的结果表明,第27层内二叠系-三叠系界线之下约2cm处有典型的发育Glossifungites遗迹相的固结基底(firmground)构造,在此构造面之上,不仅二叠纪生物碎屑的含量显著降低,碳酸盐沉积也由碳酸钙为主突然转变为白云石为主.本固结基底标志着二叠纪最末期快速海侵的到来及沉积环境和古气候的重大转变.这一海侵淹没面也见于华南浅水台地相的浙江黄芝山剖面、下斜坡-盆地边缘相的湖南江垭剖面和深水盆地相的安徽平顶山剖面,以及冈瓦纳大陆北缘的西藏色龙剖面,代表了二叠纪-三叠纪之交一次全球性快速海侵的开始. Permian-Triassic Boundary Global stratigraphic and point positions are present on the first occurrence of Hindeodusparvus in layer 27 of Section D of Meishan, Zhejiang Province. The 27th floor is generally considered as a homogeneous silty limestone, The sedimentary characteristics have not changed.The results of further study on the boundary line sequence show that there is a firmground structure typical of the developed Glossifungites facies about 2 cm below the Permian-Triassic boundary in the 27th layer, On the tectonic surface, not only the content of Permian bioclasts decreased significantly, but also the carbonate sediments changed from dolomite to dolomite. The consolidated base marks the most rapid transgression of Permian Arrivals and sedimentary environment and paleoclimate, which is also seen in the Huangzhi Mountain section of Zhejiang in the shallow southern platform of the South China Sea, the Hunan Jiangya section of the lower slope-basin margin and the Pingdingshan section of Anhui in the deep-water basin, The Tibet-Tibet section at the northern margin of the Gondwanaland represents the beginning of a global rapid transboundary movement at the turn of the Permian-Triassic period.
