Field-based research on Structural Geology, Metamorphism, and Tectonics
My research focuses on field-based studies of tectonic processes in orogenic belts. With a wide network of collaborators I work on integration of detailed field observations with various analytical and numerical modeling techniques. Recent interdisiplinary work at PGP inspired by the discoveries of deep faults at blueschist to eclogite facies metamorphic conditions in Corsica and Western Norway, has brought new light on the mechanism(s) of seismic deformation at extremely high confining pressure during subduction and continental collision.
Torgeir Andersen started his academic career in Bergen, followed by his PhD at the University of Oslo. He works on tectonic processes in orogenic belts and is a specialist on field-based studies. From his academic home base in Oslo he has built a wide network of international collaborations which led to visiting professorships at various universities, including the Universities of Oxford, UK, Cergy-Pontoise, France, California, Santa Barbara, and Rome Tre, Italy. Additionally he (co)supervised 30 MS students and 19 PhD students, 9 of whom outside Norway (Oxford-2, Liverpool-1, Paris-1, University of California-3, Witwatersrand-1, RomaTre-1). Andersen has published highly-cited papers on the problems related to burial, subduction, eduction and exhumation of ultra-high-pressure rocks and formation of supra-detachment basins.
