Optical Mineralogy at the University of the Pacific is taught as a 1-unit laboratory-based course. In this course students
not only learn the techniques for identification of minerals in thin section and get extensive experience studying minerals
in thin section. The course meets for one 3-hour lab session each week. In the first half of the semester students learn
the techniques of mineral identification: relief, fast/slow directions, interference figures, etc. In the second half of
the semester students work independently to compile a notebook of approximately 30 common rock-forming minerals and learn to
identify them in thin section. They are provided with numerous thin sections from a wide variety of rocks so that they learn
to identify the minerals in context. In the notebook, students compile optical properties and drawings of the minerals in
thin section. Students are allowed to use their notebooks on the final exam (identifying minerals in thin section) and thus
have additional incentive to generate an excellent product. Students who complete this optical mineralogy lab course are
well prepared for the petrographic work they encounter in Petrology the following semester. In addition, they develop
confidence in their own investigative and descriptive skills which serves them well in all future work.
