Medical Geology/Geochemistry An Exposure
This course note introduces students to the basic concepts of Medical Geology/Geochemistry. Medical Geology or Geochemistry is the study of the interaction between abundances of elements and isotopes and the health of humans and plants. Topics covered includes: Classification of Elements, Elemental Link Between Geosphere and Biosphere, Essential and Non-essential Elements with Reference to Human Health, Selection of Elements for Report and Presentation,NORM (Naturally Occurring Radioactive Material), TENORM, MIT-EAPS Neutron Activation Analysis Laboratory - Hands on Experience and Dust Storms.

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.
