Car (c) International Commission on Stratigraphy, April 2023Strontium isotopes. Strontium isotope stratigraphy relies on measurement of 87 Sr/ 86 Sr in marine biogenic carbonate or phosphate. Precipitation of these minerals involves incorporation of strontium from seawater, which will have an 87 Sr/ 86 Sr identical to that of oceanic values, which is of the same value globally at any point in time. The 87 Sr/ 86 Sr ratio changed systematically through ...
