This introductory
level note in Petrology is aimed at arming the students with the basic tools
needed for understanding igneous and metamorphic processes. Topics covered
includes: Metamorphism, Magmas and Lavas, Types of metamorphism, Classification
of Igneous Rocks, Metamorphic Textures, Parental Magmas and Igneous Rock,
Isograds and Metamorphic Facies, Phase Equilibria and Crystallization of magmas:
Binary diagrams, Equilibrium vs. non-equilibrium in metamorphic petrology; The
Phase rule applied to metamorphic systems, Ternary diagrams, Granites and
Granitic rocks, Metamorphic Reactions.
This lecture note
surveys the distribution, chemical composition, and mineral associations in
rocks of the earth's crust and upper mantle, and establishes its relation to
tectonic environment. The emphasis is on the use of chemistry and physics to
interpret rock forming processes.

structure, Velocity boundaries, Petrology and Tectonics, Lithosphere, Pressure
Gradient, Pressure In The Crust, Heat Sources In The Earth, Heat Production and
Heat Transfer.
