| 摘 要： | 本文报道云南石林地区石炭纪中间界线附近地层的有孔虫动物群古盘虫类4属8种。分析数据显示，这类具有独特壳壁类型和形态特征的小有孔虫类群分布，与碳酸盐岩中的亮晶、团块、海百合茎以及双壳瓣类等成分的相关系数较大。综合分析结果认为，该区古盘虫类有孔虫分布与较浅水、具中等搅动、温暖及盐度正常的潮间带环境关系密切。

| Abstract: | Eight species belonging to 4 gene- ra of Archaediscacea have been described from the foraminiferal fauna of Middle Carboniferous Strata in Stone Forest Area, Yunnan Province. The data show that this foraminiferal fauna, characterized by distinctive wall structure and morphology, has been observed to be closely related to the presence of sparite, pelletoid, crinoid and bivalve fragments in the carbonate rocks. The result of analysis reveals that the distribution of the foraminiferal fauna is closely associated with the mid-tidal environment of shallow, warm water, medium turbulence , and normal salinity. |
