Calcite is enriched in 18 O relative to water (on the PDB or VPDB scale) by about 2‰ at 5 °C and depleted by −4.4‰ at 35 °C. This corresponds to ±1‰ of δ 18 O change in the enrichment of calcite for every ∓4.7 °C change in temperature, when calcite is at an equilibrium with water of a constant 18 O/ 16 O ratio.Web
