Short summary
The Collisional Orogeny in the Scandinavian Caledonides (COSC) scientific drilling project successfully drilled a 2.5km fully cored borehole (COSC-1) through allochthonous subduction-related high-grade metamorphic gneisses and into the underlying thrust zone. This paper summarizes the scientific rationale of the project and presents first preliminary results.
