Petrology is a branch of Geosciences dealing with the description,
classification, modes of occurrence, and theories of the origins of
rocks. Rocks are divided into three main subdivisions: igneous,
sedimentary, and metamorphic. Those formed the solidification of
molten material are termed igneous, whereas those that originate from
the deposition of material from water or air are termed sedimentary,
and those formed from a previously existing rock by some process of
change are termed metamorphic. The study of igneous and
metamorphic rocks, the subject of this course, is commonly done
separate from the study of sedimentary rocks, mainly because of the
different approaches used. Petrologic studies generally fall into two
main categories: the identification and classification of rocks, and the
interpretation of these data and generation of theories on the origin of
rocks. The former will be the emphasis of field and indoors lab hours
while the latter will be treated in the lectures and problem sets.The
following topics will be dealt with during this course with the
estimated number of lectures for each topic:

3 hours lab a week are required during which the physical properties,
textures, and classification of the selected igneous and metamorphic
rocks will be carried out. The petrographic microscope will be used
extensively.
The final grade is based on:
- Two midterm exams
- Problem sets
- Lab exam
- Term paper
