Hard rock seismic methodology research course: practical aspects

The course provides an overview of the practical aspects concerning seismic methods for deep mineral exploration. The one-week fieldwork module focuses on hands-on training in seismic data acquisition and processing in a hard rock environment. The course location in central Sweden is an area that has been extensively surveyed with geophysical methods. It is complemented by a 2.3 km deep fully cored borehole that the seismic data can be compared to and which provides “ground truth”.

Students will gain experience in different aspects of seismic acquisition by a professional team of Swedish and German researchers. Later emphasis will be on processing the acquired data using a commercial seismic processing package that is in use by mining companies. At the end of the course, the novice will feel more comfortable in dealing with seismic data and the more experienced will have had the opportunity to discuss with experts various aspects of seismic acquisition and processing. Processing exercises will involve data that are acquired during the course, but also previously acquired data from the area.

Practical matters

Students should arrive in Uppsala, Sweden by Sunday morning, 3/10. Transport will be arranged to the field site via cars (about a 6-hour drive) on Sunday afternoon. Accommodation will be at a hostel close to the site (Sällsjögården). Breakfast food will be supplied, but students will need to arrange their own lunches and dinners. There are well-stocked supermarkets close to the site where food can be purchased. Transport back to Uppsala will be arranged for Saturday, 9/10.


Students need to cover their own transport costs to Uppsala. Transport will be provided from Uppsala to the field site. Accommodation, including breakfast, will be covered by the research school.
