Organisation and examination

Teaching in the first semester, review in January


Schedule online

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

The course includes the following topics: composition and nomenclature of magmatic rocks (Streckeisen, chemical classification of volcanic rocks, CIPW norm) and metamorphic rocks; graphical representation of mineral parageneses and reactions; Schreinemakers rules; binary and ternary phase diagrams.

Learning outcomes of the learning unit

The course aims at providing a basic knowledge for critical interpretation of magmatic and metamorphic phase diagrams.

Prerequisite knowledge and skills

Reference is being made to the basic principles of chemical thermodynamics and geology (GEOL0202-3).
Co-requisites courses:
Physical chemistry (CHIM0739-2)

Cristallography and mineralogy (GEOL1033-1 et GEOL1034-1)

Physics  (PHYS0188-7)

Planned learning activities and teaching methods

8 labs of 2H are devoted to the use of the nomenclature of magmatic rocks, to exercises on graphical representation of mineral parageneses and to the critical use of binary and ternary phase diagrams.

The practicals are essential for a good understanding of the course. Attendance at exercises is therefore mandatory.

Mode of delivery (face to face, distance learning, hybrid learning)

Face-to-face course

Additional information:

7 lectures of 2H each associated with 8 labs of 2H. A one day fieldtrip is scheduled.

Recommended or required readings

Booklets provided during the lectures
-The interpretation of Geological phase diagrams, E.G. Ehlers, Dover publications, 1972, 280p
-Basalts and phase diagrams, S.A. Morse

Exam(s) in session

Any session

- In-person

written exam ( open-ended questions )

Additional information:

Attendance at practical work is compulsory and conditions success. The written exam takes place in session and includes theoretical questions as well as a series of exercises to be solved.
