中文摘要:山西晚二叠世微古植物-孢子花粉非常丰富,属种众多,共发现孢子花粉60余属,140余种(包括变种和未定种).山西上石盒子组微古植物-孢子花粉主要以华夏微古植物群-孢子花粉为特征,并出现较多的欧洲和北美石炭纪和早二叠世(欧美植物群)的微古植物-孢子花粉分子;有少量安加拉(Angara)和冈瓦纳(Gondwana)微古植物群-孢子花粉出现其中,形成了十分独特的华夏微古植物群-孢子花粉.根据孢子花粉在地层中的分布和演化规律,自下而上可分为3个孢子带:3.Cordiatina subrotata-Complexis-porites polymorphus(SP)带;2.Vitreisporites signatus-Luckisporites virkkiae(SV)带; 1.Brialatisporites incundus-Nuskoisporites dulbuntyi(ID)带.依据孢子花粉在地层中的变化,详尽的讨论与国内和国外(包括欧洲、美洲和南半球的澳大利亚和南极地区)比较研究.

Characteristics of the Late Permian Palynoflora-Spore and Pollen from Shanxi
Abstract:Well-preserved pollen and spores were found in Late Permian samples from Shanxi Province .The assemblag es include approximately 140 species or forms (60 genera)of microspo res .The microflora composed chiefly of ty pical elements of Late Cathay sia microflo ra is also associated with a few forms of Permian Angara and Gondw ana Land microflora . The Paly noflora of Shanxi Province is basically different from that of Angara Province in the absence of many typical elements .I t seemed that a small number of Gondwana elements mov ed to the Shanxi Province .There existed Carbo niferous and early spores including genera of typical Western European and Norther n America Carboniferous assemblages in Upper Permian in North China . Three microflo ral assemblage zones have been reco gnized.I n ascending o rder they are:3 .Cordiatina subrotata —Complex isporites polymorphus (SP) zone ;2 .Vitreisporites signatus —Lueckisporites virkk iae (SV) zone ;1.Brialatisporites incundus —Nuskoisporites d ulbuntyi (ID)zo ne This is based on a comparative study of stratigraphic ranges of the pollen and spores recovered , in comparison w ith those from other regions in China , European , Nor th America and South Hemisphere.
