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①Remysporites-Striatolebachi-ites-Retusotriletes组合;②具肋双气囊花粉-Cordaitina-Remysporites组合;③Remysporites-Cordaitina-Geminospora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。
In recent years,many sporopollen fossils have been discovered firstly in Shiqiantan formation and Liukeshu for-
mation of Upper Carboniferous in Kelameili area,Junggar Basin. Three sets of sporopollen assemblages in the Upper
Carboniferous have been constructed from below ,besed on intervals of produced them and individual species coexisted
in combination with the previuos informations about them found in Batamayineishan formation. These are:1 )Remys-
porites-Striatolebachiites-Retusotritetes ; 2 ) Striated disaccate pollen-Cordaitina-Remysporites ; 3 ) Remysporites-Cordaitina-
Geminospora. These three sets of sporopollen 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.
