MEI650: IDENTIFICATION OF OPAQUE MINERALS (FORMERLY COM460)
This course focuses on the optical characterization of opaque minerals using a polarized light microscope and reflected light. Samples studied are mostly ore minerals, but the general principles and techniques can be applied across a broad spectrum of metallurgical and other materials. Emphasis will be on mineral identification using both plane and partly crossed polarized light, in addition to quantitative measurement of reflectance. Additional topics covered, include fundamentals of reflected light theory for isotropic and anisotropic materials, factors affecting reflectance and micro-indentation hardness, illuminating conditions (including orthoscopic and conoscopic observation), optical mineralogy and systematic schemes of mineral identification.

- Undergraduate science background
Students are expected to successfully complete a variety of tasks in the form of hands-on exercises, laboratory exercises, identifications of unknowns, and quizzes. In addition, the students are required to have 100% attendance during the course, participate in class, complete a student evaluation form and pre and post course assessment forms.
The student is notified at the end of the course whether or not they have successfully completed the requirements of the course based on:
- 100 % attendance
- class participation
- completion of all course material
- completed and signed student evaluation form
- completed pre and post course assessment forms.
Upon successfully meeting these requirements, a student is awarded a certificate of completion and IACET CEU credits, if available. Those who have not successfully passed the course requirements do not receive a certificate or IACET CEU credits.
