Internal Water Facilitates Thermal Resetting of Clumped Isotopes in Biogenic Aragonite

C. W. Nooitgedacht, H. J. L. van der Lubbe, M. Ziegler, P. T. Staudigel • Geochemistry, Geophysics, Geosystems (2021)

Abstract Biogenic and inorganic calcium carbonates contain considerable amounts of internal water, both as free and organically associated water. The oxygen isotopic compositions (δ18O) of internal water and hosting carbonate are analyzed f...
