Strontium Isotope Analysis « Center for Applied Isotope

Strontium Isotope Analysis Strontium isotopic ratios are widely used as tracers in geological processes and as indicators of provenance in an archaeological context. A significant fraction of the Earth’s 87 Sr is not primordial, but is produced by the decay of 87 Rb.
