文摘
- •
Higher 87Sr/86Sr ratios are attribute to continental strontium fluxes in restricted marginal basin.
- •
C and O isotopes in carbonates recorded a deposition under tropical conditions.
- •
Slightly negative δ13C values do not support the global Coniacian–Santonian OAE3.
- •
δ18O and δ13C anomalous values are associated with cooler clima towards to the top of section.
