Triple Oxygen Isotope Paleoaltimetry of Crystalline Rocks

Frontiers in Earth Science, 2021
Triple oxygen isotopes of hydrothermally altered minerals from crystalline rocks can be used to determine past elevations of mountain ranges. This method uses all three isotopes of oxygen (16O, 17O, and 18O) to create arrays that can be extrapolated back
