厌氧沉积的有孔虫组合中,底栖有孔虫主要由Bolivina诸种和Buliminella tenuata组成,同时含有少量厌氧标志种Suggrunda eckisi;浮游有孔虫中以Globigerrina bulloides和G.quingueloba为数较多。底栖有孔虫与浮游有孔虫数量相比,浮游有孔虫数量很少。
In the anaerobic sedimentary foraminiferal assemblage, the benthic foraminifera mainly consisted of Bolivina species and Buliminella tenuata, with a few of anaerobic marker species, Suggrunda eckisi. Among the planktonic foraminifera, Globigerrina bulloides and G.quingueloba were more abundant . Benthic foraminifera Compared with the number of planktonic foraminifera, the number of planktonic foraminifera is very small.
