Learning outcomes
Knowledge
The student who successfully completes the course will be able to understand the relationships between the physical, chemical and crystallographic properties of a mineral (or of a group of minerals) and the geological environment in which the mineral is formed. Moreover he will learn how to interpret the mineralogical transformations (phase transitions, polytypic modifications) in terms of P-T-X variables.
Assessment criteria of knowledge
The exam (in oral form) will aim at ascertaining the student's capability to describe the main topics presented during the course (e.g., crystal chemical features of a group of minerals, phase diagrams, effect of P and T on phase transformations, etc.)

Methods:

  • Final oral exam
Teaching methods

Delivery: face to face

Learning activities:

  • attending lectures
  • participation in discussions
  • individual study
  • Bibliography search

Attendance: Advised

Teaching methods:

  • Lectures
