Teaching methods
Theoretical introduction on crystallographic optics. Theoretical principles in which optical mineralogical microscope is based on. Learning to work on optical mineralogical microscope. Identification of the principal mineral species
Assessment methods and criteria
Written /practical exam on an optical microcoscope, with written report
Other information
To sit for an examination, a mandatory attendance is stated, as lectures are focussed in learning to identify mineals by means of transmitted polarized light microscope (mineralogy microscope).
Minimum number of attendance is fixed at 75% of the total, which equals 48 hours
