Trace Element Geochemistry

This lecture note explains the use Trace Element Geochemistry to understand the origin and evolution of igneous rocks. The approach is to discuss the parameters that control partitioning of trace elements between phases and to develop models for the partitioning of trace elements between phases in igneous systems, especially between minerals and melt. Beginnings of geochemistry, Thermodynamic consideration of TE solid solutions, Partition coefficient, Ionic model for bonding, Nomenclature for trace element classification, Determination of partition coefficients,  Trace element abundance variations in simple melt-solid systems, Fractional crystallization, Fractional melting, Complex melting models, Constraints on melt models arising from disequilibrium in the Th-U decay system, Ion exchange chromatography.
