Per Terje Osmundsen

About

I graduated with an MSc in regional- and structural geology in 1990 and defended my PhD at the University of Oslo in 1996.

In 1991-1992 I worked at the exploration and production division of Norsk Hydro, departments of reservoir geology and geophysics. After my PhD I worked as a Post-doc for 3 years, funded by Norsk Agip asa.

In 1999 I embarked on an almost 20 year long career at the Geological Survey of Norway (NGU) in Trondheim. Much of my geological view of the world was obtained at the NGU, through cooperation with colleagues in a highly competent and cross-disciplinary working environment.

In 2018 I started in my ci\urrent position as Professor in structural geology and basin analysis at the department of Geoscience and Petroleum at the NTNU. Here I can research, supervise and teach and thus use, develop and communicate my experience with how the Earth works.

Strukturgeologi tektonikk bassengdannelse tektonisk topografi

Research

Mitt forskningsområde er i hovedsak strukturgeologi og tektonikk, og tektonisk kontroll på eksumering, geomorfologi og bassengdannelse. Jeg arbeider mest med ekstensjons- og transtensjonsregimer, med spesielt fokus på riftmarginer. Metodikken inkluderer både tradisjonelle feltmetoder i strukturgeologi og sedimentologi, og seismisk tolkning. Jeg støtter meg videre på kollegers arbeid innenfor geomorfologi, datering av strukturer og bergarter og geofysiske metoder som gravimetri og magnetometri. Jeg er opptatt av hvordan landskaper og sedimentære bassenger påvirkes av forkastningsvekst og interaksjon, særlig på skalaer større enn det en normalt forbinder med riftforkastninger. Utvikling av detachmentforkastninger (storskala avglidningsplan), metamorfe kjernekomplekser og såkalte supradetachment bassenger er sentrale problemstillinger i mitt arbeid, både på land (Norge, Svalbard, USA, Oman) og på kontinentalsokkelen.

My research focuses mainly on structural geology and tectonics and in particular on textonic controls on exhumation, geomorphology and basin formation. I mostly work with extensional and transtensional tectonic regimes, with particular focus on rifted margins. I employ methodology that includes traditional field methods in structural geology and sedimentology as well as seismic interpretation. I normally also seek support in the work of colleagues who work with geomorphology, dating of rocks and structures, and geophysics based on magnetics and gravimetics. I study how landscapes and sedimentary basins are affected by fault growth and interaction, in particular at scales larger than those normally associated with `rift´ faults. The evolution of extensional detachment faults, metamorphic core complexes and supradetachment basins are central areas in my research on shore (e.g. in Norway, Svalbard, Western U.S., Oman) and offshore on the Norwegian continental margin.

The long-term evolution of topography and ølandscapes at rifted margins is an important topic that receives too little attention in my opinion, considering the importance of areal planning, geohazards and effects of sea-level changes in past, present and future climates. The topography of Scandinavia, Svalbard and a number of other passive margins in the world show a strong correlation with inherited rift structure, even if the rifting process ceased long time ago. Asymmetric uplift of rifted margins involve kilometer-scale reactivation of regional faults, which has resulted in a distinct footprint in the landscape.

Utvikling av topografi og landskap på riftede marginer er et viktig tema som jeg synes får for lite oppmerksomhet, særlig når en tar i betraktning viktigheten av arealplanlegging, geofarer og effekter av havnivåendring i dagens og fremtidens klima. Topografien til Skandinavia, Svalbard og en relkke andre passive marginer viser sterk korrelasjon med den nedarvede riftstrukturen, selv om riftprosessene var over for lenge siden. Asymmetrisk oppløft av riftmarginer involverer kilometer-skala reaktivering av regionale forkastninger, noe som fører til at post-rift vertikalbevegelser har satt et distinkt fotavtrykk i landskapet.
