Stable oxygen and carbon isotope record of upper Maestrichtian to lower Eocen...

Oxygen and carbon isotope ratios of benthic foraminifers were measured on the continuous middle to lower bathyal sedimentary sequence dated from the upper Maestrichtian to lower...研究人员对一套年代跨度为晚马斯特里赫特期至早……的连续中-下半深海沉积序列中的底栖有孔虫（benthic foraminifers）的氧、碳同位素比值进行了测定。
