Crustal structure of continental fragments
Tetreault, Joya; Buiter, Susanne J.H. (NGU-Rapport (2015.018), Report, 2015)Continental fragments and microcontinents are blocks of continental crust rifted off of passive margins. These relatively unthinned regions (compared to the surrounding crust) offer a perplexing conundrum as to their ... -
Sammenheng mellom bruddsoner, vanngjennomstrømning og skredutsatte løsmasser: forprosjekt i Orkanger, Trøndelag
Tetreault, Joya; Gunleiksrud, Ida; Svendby, Anne Katrine; Arntsen, Mari Lie (NGU-Rapport (2023.022), Report, 2023)Dette pilotprosjektet er et samarbeid mellom NVE og NGU der overgangen mellom fastfjellsgeologien og skredutsatte løsmasser er i fokus. Hovedtemaet er å identifisere sprekker, bruddsoner og fastfjell som utgjør mulige ... -
Scenarios of microcontinent formation applied to the Jan Mayen microcontinent
Buiter, Susanne J.H.; Tetreault, Joya (NGU-Rapport (2015.019), Report, 2015)The Jan Mayen microcontinent is a small, unique, crustal entity that was separated from the Norwegian and Greenland margins by two distinct rifting events. Seafloor spreading along the Aegir Ridge separated Jan Mayen ... -
The mantle under Africa: An overview of global and regional tomography models, lithosphere thickness models and their effect on present-day and past dynamic topography
Steinberger, Bernhard; Tetreault, Joya; Medvedev, Sergei; Buiter, Susanne (NGU-Rapport (2010.058), Report, 2010)The African plate is affected less by subduction than other plates and, as a consequence its surface experienced less subduction-related deformation while its mantle contains fewer subducted slabs. This region therefore ...
