|---|---|---|
| 1 | Magma generation and emplacement in the crust, mantle and their relation to plate tectonics. Factors affecting magma and evolution of magma (differentiation, assimilation, mixing and mingling). Phase equilibrium of ternary system: (a) Ab-An-Di system, (b) Fo-An-SiO2 system (c) Fo-Di-SiO2 and their relation to magma genesis and crystallisation in the light of modern experimental work. |
|
| 2 | Criteria for classification of the igneous rocks - IUGS classification of plutonic and volcanic rocks. Variation diagrams. CIPW Norms. Texture, chemical composition, distribution and petrogenesis of major igneous rock types such as granite, pegmatite, granodiorite, rhyolite, syenite, diorite, trachyte, andesite, gabbro, basalt, komatiite, alkaline and mono-mineralic rocks. | |
| 3 | ACF, AKF, AFM diagrams. A detailed description of each facies of low-pressures, medium- to high- pressures, very high pressure with special reference to characteristic metamorphic zones and sub-facies. Nature of metamorphic reactions and pressure- temperature conditions of metamorphism. Mineral assemblages and application of mineralogical phase rule to metamorphic rocks. Iso-reactiongrad, schreinemakers rule and construction of petrogenetic grids. |
|
| 4 | Metasomatism, metamorphic differentiation. Anatexis and origin of migmatites, granitisation in the light of experimental studies. Regional metamorphism and paired metamorphic belts in reference to plate tectonics. Ultra-high temperature, ultra-high pressure and ocean floor metamorphism. Study of charnockite, khondalites and gondites. Regional and contact metamorphism of pelitic and impure calcareous rocks. | |
