文摘
- •
Sr, C, O isotopic data of well-preserved Campanian chalk from eastern Poland is shown.
- •
Early-diagenetic calcite cementation did not alter the bulk isotopic composition.
- •
δ13C and paleotemperature drop during the Campanian.
- •
Belemnites were probably nectobenthic organisms.
- •
Vital effects of up to 2‰ were recorded in δ13C and δ18O of benthic foraminifera.
