Poppe, Sam; Holohan, Eoghan; Galland, Olivier; Buls, Nico; Van Gompel, Gert; Keelson, Benyameen; Tournigand, Pierre-Yves; Brancart, Joost; Hollis, Dave; Nila, Alex; Kervyn, Matthieu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Magma intrusions grow to their final geometries by deforming the Earth's crust internally and by displacing the Earth's surface. Interpreting the related displacements in terms of intrusion geometry is key to forecasting ...

Kjøll, Hans Jørgen; Galland, Olivier; Labrousse, Loic; Andersen, Torgeir Bjørge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)gneous dykes are the main magma transport pathways through the Earth’s crust, and they are considered to mainly accommodate for tectonic extension in volcanic rifts. Dykes are typically considered to result from brittle ...

Guldstrand, Frank Bo Buster; Galland, Olivier; Hallot, Erwan; Burchardt, Steffi (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Volcanic eruptions pose a threat to lives and property when volcano flanks and surroundings are densely populated. The local impact of an eruption depends firstly on its location, whether it occurs near a volcano summit, ...

Rabbel, Ole; Palma, Octavio; Mair, Karen; Galland, Olivier; Spacapan, Juan Bautista; Senger, Kim (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Igneous intrusions in sedimentary basins can influence basin-scale fluid flow and petroleum systems in various ways. They may act as barriers, preferential pathways or even reservoirs for fluids. The fracture networks of ...

Souche, Alban; Galland, Olivier; Haug, Øystein Thorden; Dabrowski, Marcin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Rock failure accommodating the emplacement of magmatic intrusions is controlled by the local stress regime within the host rock. Most of the mechanical models addressing rock failure conditions (e.g., for a given tectonic ...

Rabbel, Ole; Hasenclever, Jörg; Galerne, Christophe Yann; Galland, Olivier; Mair, Karen; Palma, Octavio (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Sills emplaced in organic-rich sedimentary rocks trigger the generation and migration of hydrocarbons in volcanic sedimentary basins. Based on seismic and geological observations, numerical modeling studies of hydrothermal ...

Bertelsen, Håvard Svanes; Rogers, Benjamin David; Galland, Olivier; Dumazer, Guillaume Henri; Benanni, Alexandre Abbana (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The mechanics of magma emplacement in the Earth's crust corresponds to the flow of a viscous fluid into a deforming solid. The Earth's crust through which magma is emplaced is visco-elasto-plastic, and field observations ...

Rincón, M.; Márquez, A.; Herrera, R.; Galland, Olivier; Sánchez-Oro, J.; Concha, D.; Montemayor, A.S. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The measurement of surface deformation in analogue models of volcanic and tectonic processes is an area in continuous development. Properly quantifying topography change in analogue models is key for a useful comparison ...
