摘要： 近年在准噶尔盆地东部克拉美利地区上石炭统石钱滩组及六棵树组下部首次发现孢粉化石。根据这些孢粉化石产出层位及共存的各门类化石,并综合前人在巴塔玛依内山组所发现的孢粉化石资料。自下而上建立了该区上石炭统三个孢粉组合,即①Rernysporutes- Strialolebachi-tes- Retusotrietes组合;②具肋双气章花粉- Cordatina- Rernysporites组合;③Rernysporiles-Cordoitina-Geminospura组合。这三个孢粉组合中不但含有安加拉植物地理区及欧美植物地理区的分子,而且含有冈瓦纳植物地理区的分子,显示了该区植物群的过渡性特点。

Abstract: Ln recent years,many spotopollen fossils have been discovered firstily in Shiqiantan formation and Liukeshu for-mation of Upper Carbonifetous in Kelameili area,Junggar Basin. Three sets of sporopollen assemblages in the Upper Carboniferous have been constructed ftom below, based on intervals of ptoduced them and individual specics coexisted in combination with the previuos informations aoout them found in Batamayineishan formation. These are :1 )Remy8-poriles-. Striatolebachites- Relusotrietes 2 ) Striated disaccate pollen-Cordaitina-Remysporiles; 3) Remnysporiles-Cordaitina-Geminospora. These three sets of sporopolen assemblages contain not only molecules similar to Angara flora province and Euramerian flora province, but also Gondwana flora province, indicating transitional characteristics of flora of Kelameili area.

Key words: Eastern Junggar Basin, Kelameili area, Lale Carboniferous, Sporopollen assemblage sequerices
