1st Week
INTRODUCTION to Petrography of Magmatic & Metamorphic Rocks
Subjects covered: requirements of the course, description of igneous (magmatic) rocks, a subdivision of magmatic rocks into intrusive (plutonic) and extrusive (volcanic) rocks. Difference between magma and lava. Explanation of the terms “petrography, petrology, and petrogenesis”. Field studies: how, where and for which aim do we (the geologists) collect rock samples? Preparation of rocks for petrographic studies: cutting, slicing, and polishing the rocks, turning them into thin sections for petrographic studies. Polarized microscopes. Advanced techniques used in petrological studies: types of geochemical analyses and analytical equipment used for the analyses of rock samples. Introducing the teaching material used in this course.

2nd Week
Intrusive & Extrusive Magmatic Rock Structures
Subjects covered:
Intrusive rock structures: batholiths, stocks, sills, dykes, laccoliths, lopoliths, and magmatic veins. Ring dykes and cone sheets. Classification of Plutons in Relation to Geologic Events: pre-, syn- and post-tectonic plutons. Classification of plutons according to their emplacement depths: Catazone, Mesozone, Epizone intrusives. Contact metamorphism around the plutons. Compositional zonations in plutons & magma chambers.
