This note covers
the following topics: Global considerations, Physical properties of magmas,
Major, minor and trace element chemistry, Controls of magmatic evolution, Trace
elements, Radiogenic isotopes, and stable isotopes as tracers of magmatic
processes, Igneous rock textures, Ultramafic and related rocks, Basalts, gabbros
and related rocks, Orogenic igneous rock associations, Granites and migmatites,
Continental alkalic basalts and related rocks.
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
note explains the following topics: Placing rocks in tectonic or planetary
context, Making igneous rocks, ,Magmas, Stable minerals and assemblages,
Chemical petrology, Making metamorphic rocks, Metamorphic textures, 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 and heat produciton in Earth, Introduction to igneous rocks,
Subduction zones, Classification of igneous rocks, Thermodynamics, Igneous
textures, Thermodynamics and Layered Mafic Intrusions, Heat transfer and intro
to geochemistry, Long Valley overview and volcanic structures, Mantle
composition and melting, Mantle geochemistry and continental alkaline rocks.
