Clearly, metasomatism coincident with magmatism is important, but it cannot yield the large variations in daughter radiogenic isotopes observed among islands because they require millions or billions of years to develop from parent isotopes having long half-lives.

General topics include basic principles of atomic physics, including nuclear systematics decay modes of radionuclides, radioactive decay and geochronometry, radiogenic isotope geochronometers, including a complete range of methods, the geochemistry of radiogenic isotopes, including igneous rocks, water, and sediment, and the oceans, short-lived radionuclides, and fractionation of stable isotopes.
Isotopes; principles and applications, 3d ed by SciTech Book News
Radiogenic isotopes (isotopes produced by radioactive decay of parent isotopes--lead 206 produced by decay of uranium 238, for instance) are important natural tracers for determining when rocks were formed.
