The objective of this course is to teach identification of rock
forming minerals by optical and X-ray diffraction (XRD) techniques.
Principles of optical mineralogy and XRD will be covered in
lecture-lab sessions. Students will learn to identify minerals and
rock textures by working on mineral thin sections specially prepared
for this course. Instructor, using a microscope-TV system and the
same thin sections given to students, will demonstrate and discuss
characteristic features of minerals. Students' learning outcome will
be assessed by four short quizzes and a number of mineral
identification reports written by the students.
Final grade will be determined as follows: quizzes 30%; mineral
identification reports 40%; Final exam 30%.
