    The identification and measurement of ground deformations in urban areas is of great importance for determining the vulnerable parts of the cities that are prone to geohazards, which is a crucial element of both sustainable ...

    Rock failure under shear loading conditions controls earthquake and faulting phenomena. We study the dynamics of microscale damage precursory to shear faulting in a quartz‐monzonite rock representative of crystalline rocks ...

    Hydration of a nominally dry rock can cause expansion of the solid volume, resulting in reaction‐induced fracturing and an associated increase in the porosity and permeability of the rock. We study the effect of confinement ...
  • Aben, F.M.; Doan, ML; Gratier, JP; Renard, Francois (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Postseismic recovery within fault damage zones involves slow healing of coseismic fractures leading to permeability reduction and strength increase with time. To better understand this process, experiments were performed ...
  • Pluymakers, Anne Marie Henriette; Liu, J.; Kohler, Felix; Renard, Francois; Dysthe, Dag Kristian (Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)
    We present an experimental method to study time-dependent, CO2-induced, local topography changes in mm-sized composite samples, plus results showing heterogeneous swelling of coal and shale on the nano- to micrometer scale. ...
  • Aben, F.M.; Doan, M.-L.; Gratier, JP; Renard, Francois (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    In contrast to coseismic pulverization of crystalline rocks, observations of coseismic pulverization in porous sedimentary rocks in fault damage zones are scarce. Also, juxtaposition of stiff crystalline rocks and compliant ...
  • Kaduri, Maor; Gratier, Jean-Pierre; Renard, Francois; Cakir, Ziyadin; Lasserre, Cécile (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Aseismic creep is observed at surface along several segments of the North Anatolian right‐lateral active fault in Turkey, a major plate boundary between Eurasia and Anatolia. Identifying the mechanisms that control creep ...
  • Panahi, Hamed; Kobchenko, Maya; Meakin, Paul; Dysthe, Dag Kristian; Renard, Francois (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    The statistics and dynamics of fractures formed during the accelerated maturation of kerogen-rich shale was investigated by heating Green River Shale (R-8 unit, Piceance Basin, northwestern Colorado) core samples while 3D ...
  • Lafay, Romain; Montes-Hernandez, German; Renard, Francois; Vonlanthen, Pierre (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    In order to better understand the microtextural changes associated with serpentinization reactions, natural millimeter-sized olivine grains were experimentally reacted with alkaline NaOH and NaHCO3 solutions at a temperature ...
  • Dunkel, Kristina G; Austrheim, Håkon Olav; Renard, Francois; Cordonnier, Benoit; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Dehydration of partly or completely serpentinized ultramafic rocks can increase the pore fluid pressure and induce brittle failure, a process referred to as dehydration embrittlement. However the extents of strain localization ...
  • Teixeira, Marcello Goulart; Donze, Frederic; Renard, Francois; Panahi, Hamed; Papachristos, Efthymios; Scholtes, Luc (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    In several geological environments, chemical reactions are coupled to rock deformation and the associated stresses induced locally interact with the far field loading. This is the case in immature shales that undergo burial ...
  • Renard, Francois; Cordonnier, Benoit; Kobchenko, Maya; Kandula, Neelima; Weiss, Jérôme; Zhu, Wenlu (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    Precursory signals, manifestations of microscale damage that precedes dynamic faulting, are key to earthquake forecasting and risk mitigation. Detections of precursors have primarily relied on measurements performed using ...
  • Heap, Michael; Reuschle, Thierry; Baud, Patrick; Renard, Francois; Iezzi, Gianluca (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Stylolites are planar features that form due to intergranular pressure solution. Due to their planar geometry and relative abundance in limestone reservoirs, their impact on regional fluid flow has attracted considerable ...
  • Linga, Gaute; Mathiesen, Joachim; Renard, Francois (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    In a porous rock, the spatial distribution of the pore space induces a strong heterogeneity in fluid flow rates and in the stress distribution in the rock mass. If the rock microstructure evolves through time, for example, ...
  • Renard, Francois; Putnis, Christine V; Montes-Hernandez, German; King, Helen E.; Breedveld, Gijs D.; Okkenhaug, Gudny (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)

    Siderite, the iron carbonate mineral, occurs in several geological environments and contributes to both the global iron and CO2 cycles. Under crustal conditions, this mineral may dissolve, releasing iron that becomes ...
