GEOS5508 Isotopes to Petrogenesis



This unit focuses on the use of key stable and radiogenic isotope systems for unravelling Earth's evolution. The unit examines the basic principles behind nucleosynthesis, radioactive decay and stable isotope fractionation as a basis for exploring the two main applications of isotope geochemistry, namely geochronology and the isotope tracing of geological processes. Emphasis is placed on the petrogenesis of igneous and metamorphic rocks, as recorders of the dynamic history of Earth's mantle and continental crust, with implications for the evolution of the atmosphere and oceans, and on understanding the sources of metals in ore deposits. The use of short-lived 'extinct' radiogenic isotope systems for deducing the timing of very early planetary processes is also outlined. The unit includes an overview of the techniques and instruments used for measuring isotope ratios in geological samples with some practical work.
