Conglomerates, strain and students

Students examining and calculating strain geometry, concluding that we are dealing with constriction at this particular site.

Good structural localities near campus is a wonderful thing to have. One of several good sites in the vicinity of the U of Bergen campus is the strained conglomerates of Sandviksfjellet. You will find a short description on my website under Local stuff/Geology of the Bergen Arcs. It’s a great place to bring students and structural geologists in general, because of its nearness to the town and its spectacularly deformed and well-exposed strained conglomerates.

The strain geometry changes from flattening to constrictional and back to flattening as we move through the map-scale fold structure, and one explanation is given in publication 2 of the publication list at my website.

We (Prof. Joachim Jacobs, myself and our structure class) were up there this morning, and it is always a pleasure to see these awesome rocks.

Visit this locality if you ever get to Bergen!
