A two-stage thickening and stabilization model for the formation of cratonic lithosphere Hongliang Wang (UiB) How Archaean tectonics was capable of producing virtually indestructible cratonic lithosphere remains a topic of considerable debate. Recent geophysical and petrological studies refuelled the debate by …

Seismicity of the Nordland area, Norway Jan Michalek University of Bergen ABSTRACT: The Nordland area (65-70N; 8-18E) is tectonically active part of Norway. Enhanced seismicity may reflect on off-shore subsidence combined with the uplift of landmasses usually attributed to glacial …

Did the Earth move for you? From tsunami earthquakes to slow slip By Rebecca Bell Faculty of Engineering, Department of Earth Science & Engineering, Imperial College, London, UK ABSTRACT: Over the last couple of decades we have learned that a whole …
Long-term coupling and feedbacks between surface processes and tectonics during rifting Thomas Theunissen, Ritske Huismans University of Bergen, Department of Earth Science , Allegaten, 41 5020 Bergen Whereas significant efforts have been made to understand the relationship between mountain building and surfaces …
We have visitors in the Geodynamics group so we will be running a small workshop on rifting from 10.00 to 14.30 in the PhD lunchroom (3rd floor). You can find the tentative program below. 10.00-10.45: Jan Inge Faleide (UiO): North Atlantic …
TITLE: From orogen to rifted passive margin formation in Brazil: numerical geodynamic modeling considering structural inheritance, rheology and lithospheric structure ABSTRACT: Structural inheritance is related to mechanical weaknesses in the lithosphere due to previous tectonic events, e.g. rifting, subduction and collision. The …
Title: Seismic-scale architecture of deep-seated igneous intrusions in a sedimentary basin: Jameson Land, East Greenland Abstract: Igneous sills are common components in rifted sedimentary basins globally. Much work has focussed on intrusions emplaced at relatively shallow paleodepths (0-1.5 km). However, due …
