This course provides comprehensive training in identifying and classifying rocks by examining their mineralogy and textures through both hand specimens and thin sections. Students will delve into the physical and chemical processes that lead to the formation of igneous, sedimentary, and metamorphic rocks, gaining the skills to deduce a rock's origin. A significant component of the course includes practical lab sessions where students will analyze rocks using hand specimens and the petrographic microscope. The course is taught by two instructors: one covers the igneous and metamorphic modules, while the other focuses on the sedimentary rocks. The students are evaluated with group midterm exams following the completion of the first two modules.
