| 摘 要： | 川西北广元旺苍王家沟剖面二叠系栖霞组小有孔虫动物群由14属27种组成(含比较种、亚种而不含未定种),其中Globivalvulina属及Palaeotextularidae科的物种分异度最高,合计约占总种数的50%。在系统分类的基础上,建立了Globivalvulina组合,作为识别该区二叠纪最大海进时期的标志性动物群。通过对该剖面栖霞组小有孔虫动物群的研究,不仅丰富了四川盆地二叠纪有孔虫的资料,而且为川西北王家沟剖面栖霞组与华南其他地区同期地层的对比提供了更多生物方面的依据。

| Abstract: | The Permian non-fusulinid foraminifers of the Chihsia Formation are collected from Wangjiagou section in Wangcang County,Northwestern Sichuan Basin.The Chihsia Formation of Wangjiagou section is a suit of medium-bedded to thick-bedded limestones,with thickness of about 108 meters.Based on the systematic study to the Chihsia Formation,27 species of 14 genera(including conformis species and subspecies) of the non-fusulinid foraminiferal fauna have been recognized in the Wangjiagou section.The Globivalvulina a... |
