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.
