EOSC538 is offered every second or third year to 5-10 graduate and advanced undergraduate students who have completed certain prerequisite third-year courses. In this course, students learn how to assess the diamond potential of a target area, construct geological models of diamond deposits, and identify all geological samples encountered during exploration. The course time is equally divided between lectures and practical labs and tutorials. The course is co-taught with UBC Adjunct Professors B. Scott Smith and E. Smith, who contribute industrial expertise in kimberlite petrology and diamonds. We also invite consultants and company geologists as guest speakers to leverage Vancouver's unique position as a hub for Canadian diamond exploration. During the course, students visit a consulting company and a gemological lab, network with company geologists, and gain insights into their daily tasks and workflows. The course mark is based on one lab assignment, a lab exam and an individual term project. The project is chosen by students from real case studies that focus on either geochemical analyses or a suite of thin sections. The lab exam requires students to construct a geological model of a kimberlite body using thin sections and drill core results. Ten percent of the course grade is based on active participation in lectures and peer feedback, reflecting the interactive and student-centered nature of this low-enrollment course.
