Radiogenic Isotope Geochemistry

3 units

Applications of variations in abundance of daughter isotopes of major natural radionuclides. Topics include the use of isotopes such as 87Sr, 143Nd, 206-207-208Pb, 40Ar, 4He, etc. as isotopic tracers in petrogenetic studies, and as sources of constraints on the evolution of the Earth's mantle, crust, and atmosphere.
