Preamble


Syllabus
Part A Igneous petrology
Rationale: This part deals with the principle and mechanism of the generation of
magma, its evolution through various processes, and crystallization to form igneous
rocks.
General introduction where are igneous rocks formed?
IUGS classification and nomenclature of igneous rocks based on chemistry and mineralogy (E.g. TAS, QAPF classification schemes)
Recognizing and understanding igneous textures.
Igneous structures and field relations.
Introduction to basic thermodynamics with emphasis on phase rule.
Bowens reaction series
Introduction to phase diagrams, unary, binary and ternary phase diagrams (Albite- Anorthite, Anorthite-Diopside, Forsterite-silica, Anorthite-Diopside-Forsterite systems)
Understanding mantle melting processes, generation of basalts and basalt tetrahedron. Partial melting and its controlling factors.
Process of fractional crystallization and diversification of magmas.
Chemical Petrology: Major, trace and rare earth element composition of igneous rocks.
Understanding the relationship between plate tectonics and the generation and distribution of igneous rocks.

Part B Metamorphic petrology
Rationale: This part deals with mineralogical and textural changes that occur in response to elevated temperatures and pressures that rocks experience during deep burial within the earths crust.
Introduction to metamorphism.
Types and agents of metamorphism.
Recognizing and understanding the textures and structures of metamorphic rocks.
Understanding the relation between deformation and metamorphism.
Introduction to metamorphic facies, understanding the facies concept and facies diagram.
Metamorphic reactions Basic thermodynamics of metamorphic reactions. Understanding discontinuous and continuous reactions, reactions through chemographic diagrams.
Prograde and retrograde metamorphism.
Metamorphism of mafic rocks oceanic crust metamorphism
Metamorphism of pelitic rocks Overview of Barrow zones, Barrovian metamorphism and AFM projections.
Introduction to geothermobarometry and its application.
Pressure-Temperature paths and its relation to orogeny.
Textural geochronology

Prerequisite
Students must have taken Mineralogy and Crystallography Theory course (ES3101).
It is also strongly recommended that the student taking the Petrology theory course also takes the Petrology lab course, as these two courses are closely connected.
