| 摘 要： | 笔者近年从事河南二叠系山西组地质工作，分析鉴定孢粉化石１４７３个。计６２个属，８９个种，６个近似种，６２个未定种，２个疑源类属。其中，三缝孢占５９．４％，单缝孢占３３．１％，花粉占４．７％，疑源类占２．８％。通过综合分析对比，笔者认为：山西组孢粉组合特征与国内、外同时代地层中的孢粉组合特征基本一致；孢粉的属、种变化与山西组所产动、植物化石有相关性，并进一步佐证了山西组煤层的成煤环境属滨海潮坪和三角洲分支流间湾环境。

| Abstract: | The authots have analysed 1473 sporo-pollen fossues from Shanxi Formathnin in Permi-an System,there are 62 genera,89 species,6 affinis species,62 indeterminable species,2Acritarchs genera. Among them Triletes, Monolete,pollen,Acritarchs is 59.4,33.1,4.7 and2.8 percent respectively,The characteristics of sporo-pollen assemblages of Shanxi Forma-tion have agreed with that of same strata in the world;there have relation between change ofgenus and species of sporo-pollen and animal,plant fossiles produced in Shanxi Formation.Coal-forming environment of coalbed in Shanxi Formation belonged to littoral tidal flat anddelta interdistributary bay. |
