Petrology (GEO270)

GEO270 is an applied petrology course. You will learn to identify different minerals, and igneous, sedimentary and metamorphic rocks in the microscope, and also will get exercise doing this macroscopically. You also will learn to draw conclusions from your observations. The main part of the course focuses on sedimentary rocks.

The following concepts will be in focus:

- Igneous petrology

- Sediment petrology incl. siliciclastic rocks, carbonate rocks and diagenesis

- Metamorphic petrology

An introduction to other petrographical methods than polarisation microscopy also will be given in the course.

Learning outcome


  • Background on petrology
  • The significance of different rock types to understand the 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 macroscopically and microscopically
  • Be able to produce geology-relevant results and interpretations from petrolographic investigations
  • Be able to apply petrological concepts for the exploration and production of hydrocarbons or other reservoirs

General competence:

  • Use petrological 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
