Stable oxygen and carbon isotope ratios of foraminifera and test results afte...

We report oxygen and carbon stable isotope analyses of foraminifers, primarily planktonic, sampled at low resolution in the Cretaceous and Paleogene sections from Sites 1257,...本研究报道了采自1257等站位白垩系与古近系剖面、以低分辨率采样的有孔虫（foraminifers，主要为浮游有孔虫）的氧、碳稳定同位素分析结果
