摘要
福建下一中二叠统地层发育良好、序列清楚 ,与类共生的小有孔虫动物群计有 2 4属 94种 ,其中新种 3个 .根据小有孔虫化石群垂直分布特点 ,可分为五个小有孔虫组合带 ,自下而上为 :Globivalvulina Nodosaria组合带 ,Geinitzina Pachyphloia组合带 ,Langella Pseudoglandulina组合带 ,Hemigordiusqinglongensis Cribrogenerinacelebrata组合带及Hemigordiopsis Hemigordius组合带 .这五个小有孔虫组合带在福建均属首次发现 ,在国内也很少报道 .这发现不但为下一中二叠统的地层时代归属又提供了一佐证 ,而且填补了这段地层小有孔虫资料的空白 .
The Lower Middle Permian is well developed and widespread in Ninghua,Zhangping,Longyan,Wuping districts of Fujian.Based on the vertical distribution of the smaller foraminiferal faunas,the Early Middle Permian foraminifer bearing limestone may be divided into five smaller foraminiferal assemblages:Globivalvulina Nodosaria assemblage,Geinitzina Pachyphloia assemblage,Langella Pseudoglandulina assemblage,Hemigordius qinglongensis Gribrogenerina celebrata assemblage and Hemigordiopsis Hemigordius assemblage.These five assemblages are first discovered in Fujian,and so reported very little in China,which provides new evidence for dating the Lower Middle Permian strata in this region,and fill in the gaps in material of smaller foraminifers in a section of stratum.
