Final Exam

Each student is expected complete a project on the subject of their choice. The topic must pertain to some aspect of clay mineralogy (either a lab project or a library referenced paper are possible). An abstract, figures, and list of references should be provided. Grade is determined as follows: Midterm exam (20%), Final exam (30%), Labs (40%), Project(10%).
