Petrology (GEO270)

GEO270 is an applied petrology course. You will learn to use different petrographic methods. You will learn to identify different minerals, and igneous, sedimentary and metamorphic rocks microscopically. You also will learn to draw conclusions from your observations. The main part of the course focuses on sedimentary rocks.

NB! This is an elective course and may be cancelled if fewer than 10 students are enrolled by August 20th.

The following concepts will be in focus:

  • Igneous petrology
  • Sediment petrology incl. siliciclastic rocks, carbonate rocks and diagenesis
  • Metamorphic petrology

Polarisation microscopy and other petrographic methods will be used in the course.

Learning outcome


  • Background on petrology
  • The significance of different rock types to understand the Earth's subsurface
  • The significance of global geological processes and applications, crystallization and diagenetic processes
  • How to use polarizing microscopes
  • How to identify common minerals in different rock types
  • How to use petrology for reservoir-related questions


  • Be able to identify rocks microscopically
  • Be able to produce geology-relevant results and interpretations from petrographic investigations
  • Be able to apply petrological concepts for the exploration of reservoirs

General competence:

  • Use petrographic results together with other geoscientific information for large-scale geological interpretations
  • Be able to communicate and explain geological elements and processes that are relevant in order to understand the structure of the Earth, petroleum systems, economic accumulations of hydrocarbons, and other related activities within engineering and science

Required prerequisite knowledge

GEO100 Earth, Energy and Climate

Recommended prerequisites

GEO110 Sedimentology and Stratigraphy, GEO120 Sedimentology and Structural Geology

The course has a continuous assessment (portfolio). The portfolio is composed of 12-14 tasks during and at the end of the semester with submission deadlines of approx. 1 week for each of the assignments. A detailed course-activity plan that includes the portfolio will be available at semester start.This is the last year GEO270 is offered and therefore students who fail have no opportunity to take the course again.

Course assessment

There must be an early dialogue between the course supervisor, the student union representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital subject evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
