Why Non-traditional Isotopes?? Cosmochemistry? Condensation and evaporation ? Metal segregation? Redox state? Nucleusynthesis
Why Non-traditional Isotopes?? Biochemistry? Biologically utilised: Fe, Cu, Zn, Mo, Ca, Mg, etc.
Traditional & Non-traditional Isotopes? Stable isotopes (e.g C, O, S) have been used to address some major questions in Earth and solar system sciences over the last few decades:– Climate change, – Carbon cycling, – Solar nebular processes and planet formation.
