准噶尔盆地东北缘孔雀坪剖面金沟组孢粉组合中Protohaploxypinus,Striatoabieites等具肋双气囊花粉非常发育,类型丰富,达7属32种之多;Cordaitina,Zonalasporites等单气囊花粉分异度较高,但含量较低;少量出现单沟花粉、具肋纹花粉、无肋双气囊花粉和蕨类植物孢子等。所见孢粉类型中约1/2的已知种在新疆北部只见于二叠纪地层中,1/3已知种在晚石炭世至二叠纪地层中均可见到。孢粉组合特征与盆地南缘下二叠统塔什库拉组上部组合相似,地质时代为早二叠世空谷期。
The double-balloon pollen with ribbed ribs of Protohaploxypinus and Striatoabieites in the Jinggou Formation sporopollen assemblage in the north margin of Junggar Basin is well developed and is rich in up to 32 genera in 7 genera. The single balloon pollen diversity of Cordaitina and Zonalasporites is very high, But low content; a small amount of single ditch pollen, ribbed pollen, rib-free double balloon pollen and fern spores. About one-half of known species of sporopollen type are found in the Permian strata in northern Xinjiang and one third of all known species are visible in the Late Carboniferous to Permian strata. The characteristics of sporopollen assemblages are similar to the upper assemblages of the Lower Permian Taxicula Formation in the southern margin of the basin, and the geological epoch is the Holocene Holocene.
