| Preamble |
|---|
| Introduction: This course aims at study and understanding of earth processes using geochemical principles and employing geochemical tools: abundances and ratios of trace elements and isotopes. Emphasis will be on quantification approach, e.g. calculation of rates of processes, mass balance of elements and isotopes in steady state and non-steady state conditions, quantifying temporal variation of elemental and isotope composition following perturbation of a reservoir.
