Research projects and activities

Caledonides

picture

I grew up in the heartland of the Caledonides. The first rocks I saw and wondered about were mylonitic gneisses and fault rocks. The Caledonides and all of its mysteries are something that will always follow me.

Post-Caledonian

picture

After the Caledonian continent-continent collision there is 400 m.y. that we do not know a whole lot about, at least not in Scandinavia. I am interested in how new and old techniques can be combined to elucidate this history.

Colorado Plateau

picture

Ahhh ... the Colorado Plateau is the world's greatest geo-playground, particularly for geoscientists interested in the deposition and deformation of sedimentary rocks. Very different from the Caledonides indeed.

Fault interaction

picture

The way that faults grow and interact has fascinated me for decades. The scale independence of many aspects of fault growth and interaction is intriguing, and there is still more to be explored in this field.

picture

Deformation bands

picture

Deformation bands are very interesting and diverse strain localization features that only occur in quite porous sediments and rocks, notably sandstones. Among other things they change the permeability structure of reservoir rocks.

picture

SALTEC

picture

Salt and evaporites are different types of rocks in that they flow even at (near-)surface conditions. The most peculiar types of structures can evolve, and the presence of salt can totally change the structural pattern of a region.

picture

COPS

picture

COPS stands for Contraction of Porous Sandstones and this activity is about how contraction affect porous sandstones and how the resulting structures compare to those formed in the extensional tectonic regime. Reverse faults and thrusts are keywords.

picture

MULTIRIFT

picture

Rifting of continental crust is an interesting process, well expressed in the North Sea region. This project explores the relation between basement structures and those formed during two post-Carboniferous phases of rifting in the northern North Sea rift system.
