摘　　要：该文报道了Ｃｌａｒｋｉｎａｃｈａｎｇｘｉｎｇｅｎｓｉｓ，Ｃ．ｄｉｃｅｒｏｃａｒｉｎａｔａ，Ｃ．ｓｐ．１ｃｆ．ｔｕｌｏｎｇｅｎｓｉｓ，鱼牙和海绵化石，以及六方双锥石英晶体、微球粒、玻屑和锆石单晶体在江西信丰地区二叠三叠系（简称Ｐ＼Ｔ，下同）界线粘土岩中的发现．通过对江西桃江、浙江煤山、西藏色龙Ｐ＼Ｔ界线剖面与江西东岭、沿沟Ｐ＼Ｔ界线剖面相互对比后认为，以Ｃ．ｔｕｌｏｎｇｅｎｓｉｓ或Ｃ．ｍｅｉｓｈａｎｅｎｓｉｓ首次出现的点位探求Ｐ＼Ｔ界线的ＧＳＳＰ。The Clarkina changxingensis,C.dicerocarinata,C.sp.1 of cf. tulogensis,Pisces teeth Sponge microfossils,and Hexagonal bipyramidal quartz,Microspherolite,Hyaloclastic fragment,Zircon have been discovered from the boundary clay bed in the Section of Permian Triassic(shorted as “P\T”) boundary in Xinfen,Jiangxi.Based on correlation of P\T boundary Sections in Taojiang of Jiangxi,Meishan of Zhejian,Selong of Tibet with that in Dongling Yangou of Jiangxi,the persent writes think that the first appearana of the C. tulongensis or C.meishanensis in the useful for definition of GSSP of the P\T boundary.
