(Table 1) Oxygen and carbon isotopic values of benthic foraminifera from the ...

Stable isotopic data from benthic foraminifera indicate the occurrence of at least three deepwater masses in the late Maastrichtian ocean. Given mean oceanic d18Ow of -1.0 per...底栖有孔虫（benthic foraminifera）的稳定同位素数据表明，马斯特里赫特期晚期的海洋中至少存在三个深水水团。已知该时期海洋水体的平均d18Ow值为-1.0‰……
