| Mineralogy (20 lectures) & Geochemistry (20 lectures)
Scope Introduce students to detailed mineralogy for understanding petrology. This includes systematic mineralogy of silicate and nonsilicates, mineral chemistry, properties and analysis, crystallography and optical mineralogy. To study and understand earth processes using geochemical principles and employing geochemical tools such as major and trace elemental abundances and ratios, 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. Course Content Mineralogy Broad classification: definitions, properties of minerals & environments of formation. Crystal Chemistry: Chemistry of elements, Bonding and packing in mineral Chemical analysis of minerals, Mineral formulae. Crystallography: Introduction to symmetry, Symmetry, Mathematical Crystallography, Diffraction. Optical Mineralogy: Introduction to Optics, Optical Crystallography & Crystal Chemistry. Systematic Mineralogy: Nomenclature and classification of minerals, Silicate minerals, Environments of mineral formation Geochemistry Ionic substitution in crystals: governing rules, distribution coefficients and temperature dependence, geochemical classification of elements and implication for earth differentiation. Trace element geochemistry: definition, classification, importance in the study of crust- mantle evolution processes, coupling trace elements with isotopes, and use them as tracers in the evolutionary history of rocks. Oxidation-reduction reactions: balancing of redox reactions, Eh-pH of natural waters, stability of iron compounds, oxidation-reduction in organic compounds, importance and applications of redox geochemistry with examples. Aqueous geochemistry: alkalinity in waters and controlling factors, solubility of carbonate and silicate minerals, carbonate equilibrium and implications for atmospheric CO2. Chemical kinetics: rates of dissolution and precipitation, material transport: advection, diffusion, Ficks law of diffusion in steady and non-steady state, temperature dependence of rates, diagenesis of sediments, influence of digenesis on sediment porewater profile. Geochemical Cycles: The principle of mass balance, mass balance of major and trace elements in the oceans. Mass balance equations in steady state and non-steady state conditions, temporal evolution of elemental and isotope composition following perturbation of a reservoir. |
