The Shezhi Formation of Yipinglang coal series consists mainly of arenaceous shale and carbonaceous shales with medium-grained sandstones in the basal part.The total thickness of the formation amounts to 203.9 metres.The shales are rich in fossil Sporo-pollen and plants.The fossil spores and pollen contain 55 genera and 74 species,including 19 new species. The Sporo-pollen assemblage of the Shezhi Formation is characterized by the absolute predominance of the spores of pterdophyta(54.5%)and the pollen of gymno- sperms(45.5%).The spores are characterized by the abundance of Dictyophyllidites, Cyathidites,Concavisporites,by the diminution of Leiotriletes,Converrucosisporites, Granulatisporites and Cibotiumspora.The pollen grains are characterized by the abundance of Ricciisporites,Ovalipollis,Cycadopites and Psophosphara,and by the presence of Quadraculina,Podocarpidites,Rhaetipollis and ancient striate conifers. Based on the characters of the Sporo-pollen assemblage and associated occurrence of plant fossils(Dictyophyllum nathoreti,Clathropteris meniscioides,Pterophyllum sinese,etc.),the Shezhi Formation may be referred to Norian-Rhaetian stage of Upper Triassic age. According to the flora reflected by the present Sporo-pollen assemblage and plant fossils,it may be supposed that the climate of the Yunnan Basin in the Late Triassic period was certainly rather warm and wet.It may be referred to tropical- subtropical type similar to that of South-eastern Asia at the present time.

云南禄劝大根村一平浪煤系舍资组孢粉组合中,蕨类植物孢子占54.5%,稍为超过裸子植物花粉(45.5%)。孢子中以 Leiotriletes,Concavisporites,Dictyophyllidites,Cyathidites,Gra-nulatisporites,Converrucosisporites 和 Cibotiumspora 为主;花粉中以 Ovalipollis,Ricciisporites,Alisporites,Cycadopites 和 Psophosphaera 为主,尚有一定数量的 Rhaetipollis,Taeniaesporites,Protohaploxypinus 和 Striatopiceites。由于欧亚和北美大陆晚三迭世诺利-瑞替期孢粉组合通常都具有上述特征,笔者认为禄劝舍资组的地质时代应属诺利-瑞替期。当时的气候湿热,与现今东南亚相似,属热带-亚热带型。

Through the study of the spores and pollen from 21 cores of Changhe basin, lots of spores and pollen fossils have been obtained. The Paleogene spores and pollen of Changhe basin may be divided into 4 spores and pollen zones in ascending order. The ages of strata are inferred from the character of spores and pollen assemblages, and the paleovegetation succession and the paleoclimate changes are also discussed.1. The lower part of the second member of Changhe group:It reflects the coniferous and broad leaf mixed...

Through the study of the spores and pollen from 21 cores of Changhe basin, lots of spores and pollen fossils have been obtained. The Paleogene spores and pollen of Changhe basin may be divided into 4 spores and pollen zones in ascending order. The ages of strata are inferred from the character of spores and pollen assemblages, and the paleovegetation succession and the paleoclimate changes are also discussed.1. The lower part of the second member of Changhe group:It reflects the coniferous and broad leaf mixed forest by the predominance of Ulmaceae of the Late Paleocene-Early Eocen when the climate was of a hot and a little dry tropical-subtropical type.2. The upper part of the second member of Changhe group:It reflects the evergreen broad-leaf and deciduous broad-leaved mixed forest or coniferous and broad leaf mixed forest dominated by angiospermae of the Middle and Late Eocene. The climate at that time was of a warm and moist southern subtropical type.3. The third member of Changhe group:It reflects the coniferous forest or coniferous and broad leaf mixed forest by the predominance of Taxodiaceae, Pinaceae, etc., of the Early Oligocene, an age with a warm and humid middle subtropical climate.4. The fourth member of Changhe group:It reflects the coniferons and broad leaf mixed forest mainly consisted of deciduous broad-leaved forest of the Middle and Late Oligocene, an age with a temperate and humid northern subtropical climate.

长河盆地21个钻孔的孢粉研究表明,其孢粉化石丰富。长河盆地早第三纪孢粉组合自下而上可分为4个孢粉带,从而推断了其地质时代并讨论了古植被演替和古气候变化. 1.长河群二段下部:上古新统一下始新统,以榆科占优势的针、阔叶混交林,为炎热稍干的热带—亚热带气候。2.长河群二段上部:中、上始新统,常录阔叶和落叶阔叶混交林或以被子植物占优势的针、阔叶混交林.当时为暖热湿润的南亚热带气候. 3.长河群三段:下渐新统,以杉科和杉科占优势的针、阔叶混交林,为温暖湿润的中亚热带气候. 4.长河群四段:中、上渐新统,以落叶阔叶为主的针、阔叶混交林,为温和湿润的北亚热带气候.

In this flora the dominant group is Filicopsida (8 generaand 15 species).Of which members of Dipteridaceae, Marattiaceaeand Osmundaceae are abundent. Cycadophyta consists of 6 generaand 11 species. Ginkgoales and Coniferales are rich, Pteridospermaeconsists of Ptilozamites, Lepidopteris and Ctenozamites (1 speciesper genus)....

The characters of this flora closely resembles Yipinglangflora of Yunnan, Late Triassic flora of Hunan and Jiangxi,Xujiahe and Qinghe of Sichuan, Eastern Xizang, Tonkin floraof Vietnam, Nariwa flora of Japan and East Greenland floraetc. but this flora is younger than the Daqiaodi flora found inBaoding. The age of the flora is assigned to middle Keuper-Rhaetic stage of late Triassic, The climatic of Xinlong Districtin that time was tropical-subtropical.

本文报道四川省新龙地区晚三叠世植物(包括英珠娘阿组及喇嘛垭组)29属48种。 在这植物群中,真蕨植物占优势(8属15种),其中又以扇蕨科,合囊蕨科和紫萁科植物占显要地位,苏铁类植物次之,银杏类和松柏类植物比较丰富,种子蕨类植物出现了叉羽叶和鳞羊齿等。其组合特征与云南一平浪组、四川须家河组植物群,湘赣地区,箐河以及藏东地区晚三叠世中晚期植物群极为相似。与日本成羽,越南东京和东格陵兰等地晚三叠世植物群也比较接近,所属地质时代大致相当,应属于三叠世考依卜中——晚期。指示的气候属热带——亚热带。
