湖南桑植县仁村坪上二叠统-下三叠统底部菊石动物群序列及其区域对比

Late Permian-Earliest Triassic Ammonoid Sequences from the Rencunping Section,Sangzhi County,Hunan Province,South China and Their Regional Correlation

湖南桑植县仁村坪剖面二叠-三叠系界线地层连续,菊石动物化石丰富.根据该剖面上二叠统大隆组至下三叠统大冶组底部菊石动物群的分布,自下而上划分为4个菊石带:Araxoceras-Konglingites-Sanyangites带、Sinoceltites带、Pseudotirolites-Rotodiscoceras带和Hypophiceras-Ophiceras-Lytophiceras带.通过对该剖面菊石和牙形石生物地层及其与华南其他剖面的对比可知,Araxoceras-Konglingites-Sanyangites带与牙形石Neospathodus orientalis带同期,为吴家坪期晚期;Sinoceltites带与牙形石N.subcarinata-N.wangi带同期,为长兴期晚期;Pseudotirolites-Rotodiscoceras带与牙形石N.postwangi-N.changxingensis带和N.xiangsiensis-N.changxingensis带同期,为长兴期晚期;Hypophiceras-Ophiceras-Lytophiceras带与H.parvus、I.isarcica-I.staesche和N.planata 3个牙形石带同期,相当于印度期早期.根据仁村坪剖面菊石Hypophiceras-Ophiceras-Lytophiceras带底界的出现位置,将该剖面的二叠-三叠系界线确定在第27a层的中部.水利论文Lxb'O;h CW/fF"N
