Changes in the course due to coronavirus

Autumn 2020 the exams of most courses at the MN Faculty will be conducted as digital home exams or oral exams, using the normal grading scale. The semester page for your course will be updated with any changes in the form of examination.

See general guidelines for examination at the MN Faculty autumn 2020.

Course content

This course provides an introduction to equilibria between minerals, and between minerals and different fluids and melts. The course takes you through thermodynamic principles behind the construction and interpretation of phase diagrams, and how these can be used to understand the formation conditions for the common metamorphic and magmatic rocks.

Learning outcome

After taking this subject the student will be able to:

  • interpret phase diagrams that describe the melting and crystallisation of magmatic rocks
  • construct and interpret phase diagrams that describe the stability fields of metamorphic rocks as a function of pressure, temperature and fluid composition
  • calculate the composition of aqueous solutions in equilibrium with a given mineral assemblage
  • to do simple kinematic calculations of aqueous solution composition during dissolution and precipitation reactions

Admission to the course

Students at UiO register for courses and exams in Studentweb.

Special admission requirements

In addition to fulfilling the Higher Education Entrance Qualification, applicants have to meet the following special admission requirements:

  • Mathematics R1 (or Mathematics S1 and S2) + R2

And in addition one of these:

  • Physics (1+2)
  • Chemistry (1+2)
  • Biology (1+2)
  • Information technology (1+2)
  • Geosciences (1+2)
  • Technology and theories of research (1+2)

The special admission requirements may also be covered by equivalent studies from Norwegian upper secondary school or by other equivalent studies (in Norwegian).

Formal prerequisite knowledge

The course includes a compulsory field course and excursions. A health and safety course for safety in the field must be passed before you can go on these.

In addition these HSE courses have to be taken before participating in the practicals:


There are 6 hours of lectures and practicals per week. The compulsory exercises must be approved before taking the final examination.

There are two compulsory day excursions in the course.

Attendance at the first lecture is compulsory. Students who fail to meet, are considered to have withdrawn from the course unless they have previously given notice to the Student administration (

As the teaching involves laboratory and/or field work, you should consider taking out a separate travel and personal risk insurance. Read about your insurance cover as a student.

General information about excursions at the Dept. of Geosciences.


  • Handing in two compulsory assignments from practicals and participation on the two compulsory excursions must all have been approved before the final examination.
  • Final written examination (3 hours) counts for 100%.

Examination support material

Approved calculator.

Language of examination

You may write your examination paper in Norwegian, Swedish, Danish or English.

Grading scale

Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.

Resit an examination

Students who can document a valid reason for absence from the regular examination are offered a postponed examination at the beginning of the next semester. Re-scheduled examinations are not offered to students who withdraw during, or did not pass the original examination.

Special examination arrangements, use of sources, explanations and appeals
