| Summary | This course provides an introduction to geochemistry, firstly through a short review of thermodynamics and kinetics as applied to Earth systems and then through consideration of the ¿geochemical toolbox¿: the basic principles and techniques which underlie modern geochemistry. Material covered includes classification of the elements and their behaviour in earth systems/during earth processes, use of stable and radiogenic isotopes and the application of techniques to topics as diverse as dating formation of the solar system to constraining changes in the climate and ocean record. |
