Brittle-viscous deformation of vein quartz under fluid-rich lower greenschist facies conditions
Kjøll, Hans Jørgen; Viola, Giulio; Menegon, Luca; Sørensen, Bjørn Eske (Journal article; Peer reviewed, 2015)We studied by Electron BackScatter Diffraction (EBSD) and optical microscopy a coarse-grained (ca. 0.5–6 mm) quartz vein embedded in a phyllonitic matrix to gain insights into the recrystallization mechanisms and the ... -
Continental weathering and recovery from ocean nutrient stress during the Early Triassic Biotic Crisis
Knies, Jochen Manfred; Schönenberger, Jasmin; Zwingmann, Horst; van der Lelij, Roelant; Smelror, Morten; Vullum, Per Erik; Vogt, Christoph; Fredin, Ola; Muller, Alxel; Grasby, Stephen E.; Beauchamp, Benoit; Viola, Giulio (Peer reviewed; Journal article, 2022)Following the latest Permian extinction ∼252 million years ago, normal marine and terrestrial ecosystems did not recover for another 5-9 million years. The driver(s) for the Early Triassic biotic crisis, marked by high ... -

Deconvoluting complex structural histories archived in brittle fault zones
Viola, Giulio; Scheiber, Thomas; Fredin, Ola; Zwingmann, Horst; Margreth, A; Knies, Jochen (Journal article; Peer reviewed, 2016)Brittle deformation can saturate the Earth’s crust with faults and fractures in an apparently chaotic fashion. The details of brittle deformational histories and implications on, for example, seismotectonics and landscape, ... -
Deformation mechanisms of blueschist facies continental metasediments may offer insights into deep episodic tremor and slow slip events
Giuntoli, Francesco; Viola, Giulio; Sørensen, Bjørn Eske (Peer reviewed; Journal article, 2022)Exhumed fossil subduction zones are archives of the deformation conditions and mechanisms from depths not directly accessible. Microstructural analysis of samples exhumed therefrom offers insights into the micromechanics ... -

Geology of the Northern Apennines nappe stack on eastern Elba (Italy): new insights on the Neogene orogenic evolution of the Northern Tyrrhenian Sea
Papeschi, Samuele; Ryan, Eric James; Musumeci, Giovanni; Mazzarini, Francesco; Garofalo, Paolo Stefano; Viola, Giulio (Peer reviewed; Journal article, 2021)We document the tectonic and metamorphic evolution of thrust nappes of the eastern island of Elba. The area exposes a natural cross section of the Northern Apennines hinterland, from the metamorphic basement units to the ... -
High-resolution Meso- and Microstructural Study of polyphase Deformation in the Orkanger Region, Sør-Trøndelag, Central Norway
Bekkedal, Eero Matti (Master thesis, 2015)The Orkanger Road Cut (ORC) is a 300 m long section of exposed country rock that has preserved an important record of structures linked to the tectonic history of the Mid-Western Gneiss Region. High-resolution field mapping ... -
Manual extraction of bedrock lineaments from high-resolution LiDAR data: methodological bias and human perception
Scheiber, Thomas; Fredin, Ola; Viola, Giulio; Jarna, Alexandra; Gasser, Deta; Lapinska-Viola, Renata (Journal article; Peer reviewed, 2015)Manual extraction of topographic features from Light Detection and Ranging (LiDAR) images is a quick, cost effective and powerful tool to produce lineament maps of fractured basement areas. This commonly used technique, ... -
Multiscalar Structural Study of the Brittle Deformation History in the Åna-Sira Anorthosite massif, Rogaland, Southwestern Norway
Ferstad, Anne-Line Kvale (Master thesis, 2017)The c. 930 Ma Åna-Sira anorthosite massif (ÅS) is a part of the Rogaland Anorthosite Province, situated in the county of Sokndal, Rogaland. In this thesis, multiscalar efforts are aimed at unraveling the spatial and temporal ... -
Onshore to offshore correlation of ore-forming hydrothermal systems: Geological investigations of the Reinfjord Ultramafic Complex and Southwestern Barents Sea
Ryan, Eric James (Doctoral theses at NTNU;2023:76, Doctoral thesis, 2023)Demand for mineral resources continues to grow, while political pressure, legitimate environmental concerns, and important ethical questions slow the development of new mineral resources. Simultaneously, emerging technologies ... -
