Course Objective
| 1 . |
To develop an advanced understanding of metamorphic processes, mineral assemblages, phase equilibria, and tectonothermal evolution, enabling students to interpret metamorphic terrains using mineralogical and thermodynamic principles. |
| 2 . |
To train students in the analytical evaluation of metamorphic rock textures, P–T paths, and geochronological constraints for reconstructing crustal evolution and metamorphic histories in diverse geological settings. |
Course Outcome
| 1 . |
Identify and classify metamorphic rocks, their textures, structures, and facies, and relate them to specific metamorphic grades and geodynamic settings. |
| 2 . |
Interpret metamorphic reactions and mineral assemblages using principles of thermodynamics, phase equilibria, and isograd concepts. |
| 3 . |
Analyse pressure–temperature conditions of metamorphism by constructing and interpreting phase diagrams, pseudosections, and performing basic geothermobarometry. |
| 4 . |
Explain mineral growth mechanisms and zoning patterns, and evaluate their implications for metamorphic history and P–T–t evolution. |
| 5 . |
Evaluate regional metamorphic terranes and metamorphic belts, including Indian examples, in the context of plate tectonics, crustal evolution, and migmatite formation. |
