Course Director: Dr. Bassam A. Abu Amarah ii. iii. iv. Contributer: Hashim Babakur Course Title: Igneous Petrology Course Code: 32 Geo. v. Credit hours: 3 credit hours (2++0). vi. vii. Level/year at which this course is offered: 5th level / Summer semester of the above academic year 5 th semester Course pre-requisites for this course: Optical mineralogy Course (22 Geo) & Crystallography Course (223 Geo). viii. Group Number: 66. ix. Lecture theater (room): AB 05. x. Course objectives and Learning Outcomes for this Course: a. The usages of the petrological studies of the different rock types and minerals. b. Their relation to the universe and the formation of the Earth. c. Its types and forms of magmas and their identification. Value of the economic process. Rock's relation to tectonics (earthquakes and volcanos). Geochemical relations between the magma and the formation of the rocks. Geological maps and its applications d. Gaining and understanding of the processes responsible for forming igneous rocks.

2 e. Gaining and understanding of how the chemical composition, structure and texture of rocks can be used to interpret igneous rocks processes and the geologic history of the earth. f. Identifying igneous rocks in hand specimen and thin section. We expect from our students to demonstrate, and to have the ability in analyzing, interpreting scientific data and verify the igneous rocks, and its genesis and minerals contents, either in both hand specimen, or in thin section by using polarizing Microscope and the other tools related. The student also should have abilities and competency to use, to read/construct geologic maps; in terms of the geologic and tectonic history of any region based on field studies. xi. xii. Course Description (Summer Course): The 32 Geo. Course summer session consists of 7 wks; with 28 lectures (each lecture time will be two hours), and 5 practical hours. Subsequently, the student is expected to acquire knowledge in methods and procedures of igneous petrology, and to identify minerals under the polarizing microscope and also their optical properties, and the applying its physics and chemical affinities, as well as gaining knowledge in igneous petrology and their relationships in the field.
