Goals of this course are to become familiar with the function, adjustment, and use of the petrographic microscope, to understand crystal optics and practical methods of identification of rock-forming minerals (relief, pleochroism, extinction, birefringence, etc.). The student will become familiar with most common rock-forming minerals.
