Isotope geochemistry uses the natural variations in isotopic ratios to unlock the history of rocks, water, and the atmosphere. Radioactive decay clocks in minerals reveal the ages of the oldest crystals on Earth, while subtle mass-dependent fractionation of stable isotopes records ancient temperatures, biological activity, and fluid pathways through the crust.
These simulations let you perform virtual radiometric dating, explore equilibrium and kinetic fractionation, construct isochron diagrams, calculate cosmogenic exposure ages, and unmix multi-component isotopic signatures — all with interactive controls grounded in real geochemical equations.
