Most Earth-surface calcites precipitate out of isotopic equilibrium

Oxygen-isotope thermometry played a critical role in the rise of modern geochemistry and remains extensively used in (bio-)geoscience. Its theoretical foundations rest on the assumption that (18)O/(16)O partitioning among water and carbonate minerals primarily reflects thermodynamic equilibrium. How...
