摘要
在江汉平原47号钻孔中的46.60—2.20m层位上(上更新统到全新统),含有丰富的化石硅藻,经鉴定有4个新种类,即Cymbella jianghanensis sp.nov.,C.tenuistriata sp.nov.,C.cistula(Hempr.) Grun.var.retcta var.nov.,Gomphonema tropicale Brun var.nonpunctatum var.nov..同时,对一个变种进行了重新命名和特征修改,即Eunotia clevei Grun.var.obliquestriata Qi,Lin et He,nom.nov.et char.emend..
In the upper section (46.6--2.2m, Pleistocene to Holocene) of Borehole 47 located inJianghan Plain, Jiangling County, Hubei Province, the sediments are loose sand and clay, containing abundant fossil diatoms. Among them, three species and one variety are recog-nized as new taxa; 3 other species are probably also new in characters, but they are notnamed here because only a small number of individuals have been observed.
