The kinetic oxygen cycle in chemical sediments
Temperature is probably the most fundamental parameter is Earth sciences, but vigorously debated for most of Earth’s history. Temperature derived from carbonate 18O/16O isotope ratios (δ18Oc) can be biased by i) kinetic effects, ii) alteration, or iii) late precipitation of secondary carbonates. KinO shows that each of these mechanisms is expected to follow a different trajectory in δ18Oc vs. δ17Oc space. Within this triple oxygen isotope space, different precipitation mechanisms and different types of kinetic effects fall on characteristic slopes, allowing to correct for these effects, which allows attaining absolute paleo-temperatures. Oxygen isotopes are classically analysed in materials…
