Course content

Geophysical mapping and interpretation methods used in exploration for natural resources (ores, industrial minerals, hydrocarbons), and other geological - as well as environmental tasks. The focus of the course will be on gravimetry and magnetometry and its integration with other exploration methods. Physical properties and measurements of density, susceptibility, and natural remanent magnetization. The application of magnetic mineralogy and magnetic petrology in understanding lithospheric magnetization, and magnetic mapping, from mineral to regional scale. Interpretation and modelling methods for gravity and magnetic anomalies.

Learning outcome

Knowledge: Fundamental understanding of gravity and magnetic methods used in geophysical exploration for natural resources, other geological and environmental applications focused on- and offshore Norway and related physical properties of minerals and rocks. Through project work an understanding of the relationships between physical rock properties and geophysical responses of rocks.

Skills: The students should be able to successfully perform their interdisciplinary scientific project combining geology and basic geophysics and present the results to the class. Students will acquire magnetic data in the field and use modeling programs in potential field methods. After successful completion of the course students should be able to include gravity, magnetic and other geophysical data into programs designed to explore for natural resources.

Learning methods and activities

Lectures will include geophysical principles and methodology with a focus on gravity and magnetics, petrophysical properties of minerals and rocks, magnetic mineralogy and petrology in relation to lithospheric magnetization and magnetic mapping. Practice in applying methods for different types of resources and applications, both on- and offshore, by use of modelling software. Fieldwork over one weekend is obligatory. Project and laboratory exercises will include self-study, which will include practice in applying geophysical methods including professional gravity and magnetic software and concepts for exploration of a variety of natural resources (e.g. ore deposits, ultra pure quartz, building stones, and hydrocarbons) and other geological and environmental applications. Laboratory exercises will include petrophysical and detailed magnetic measurements of different rock types. Laboratory, fieldlab, project and interpretation work counts 50% of the final grade. The course is evaluated by a reference group.

Further on evaluation

Portfolio assessment is the basis of the grade in the course. The portfolio includes a final written exam (50%) and 2 work (excercise/labwork, 25% each). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade. For a re-take of an examination, all assessments during the course must be re-taken.

Required previous knowledge

TGB4125 Mineralogy, and TGB4130 Petrology or equal. Basic courses in physics (or geophysics) and chemistry are also required.
