Advanced Igneous Rocks Geo 522)

• The course provides in depth the understanding of igneous initiation and generation processes, based on the chemical equilibrium and kinetics of the magma diffraction.

• The course will have a comprehensive perception of how magmatism processed within the earth structures and to conduct postgraduate-level research on igneous systems.

• Magmas occurrence of igneous rocks’ units, record of its attitude, structure, report on texture physical appearance, mode ( actual mineral), geochemistry and chemical composition of mantle of the earth’s xenolith derived from the upper mantle spinel lherzolites, Harzburgite, Eclogites, pyrolite, subcontinental sub-oceanic upper mantle and isotopes.

• Magmatic differentiation (diversity of magma, differentiation in wholly liquid magmas. fractional crystallization, mixing magmas, assimilation, and variation diagram).

• Modal and chemical classification of igneous rocks and magmas. Abundance and distribution of magmatic rocks ; basalt clan, andesite, the ultramafic and alkaline rocks, kimberlite, carbonatites…. Etc.. Together with an description of its origin and evolution.

• Compositional phase diagrams. 2 Component Phase Diagrams illustrating the magma behavior via different diagrams as AFM, Igneous rocks classifications and their field relations,

• Tectonic movement, Volcanism and volcanoes, thermodynamics of the rocks, Special reference on problems about the origin of selected rock types from the Arabian Shield.

• The course will involve a postgraduates'' academic learning skill via (1) communication and interaction with peers and senior researchers via assessment of topical questions; (2) scientific thinking and problem solving in applying the topics absorbed and discussed at thin section lab; and (3) self-management in preparation for weekly classroom activities.
