中国石炭系中间界线孢粉学研究新进展

New Advances in Palynology Across the Mid-Carboniferus Boundary in China

介绍国际石炭系中间界线的定义及西欧、顿涅茨盆地纳缪尔阶孢粉分带；总结中国石炭系，特别是甘肃靖远和宁夏中卫地区石炭系中间界线孢粉学研究的新进展，并指出确定中间界线的孢粉学标志。简要分析了所存在的问题，对今后的研究工作提出了建议。

The international definition on the mid-Carboniferous boundary and the Namurian palyno- logical zonations of West Europe and Donetz Basin are briefly introduced.Based on a comprehensive veview on new advances in the study of palynology across the mid-Carboniferous boundary in China,especially in Jingyuan of Gansu and Zhongwei of Ningxia,the palynological evidence for determination of the present boundary has been recognized conseqtiently.It is suggested that the study area con- cerned with palynomophs should be expanded so as to get more information about the distributlon of miospores near the mid-Carboniferous boundary in China。
