Planar features, Trace element mobilisation and recrystallization formed during lower crustal CO2 induced seismic deformation of olivine
Autor: Bjørn Eske Sørensen, Eric James Ryan, Rune Larsen, Stefanie Lode, Jostein Røstad, Thomas B. Grant
Planar deformation features are a common feature in shock-deformed olivine, both experimentally in conditions corresponding to crustal shear zones [1] and impact structures e.g., [2] and in deep crustal shear zones [3, 4]. Hence, the identification o

Geology of the Northern Apennines nappe stack on eastern Elba (Italy): new insights on the Neogene orogenic evolution of the Northern Tyrrhenian Sea

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 overlying continent- and ocea

Infiltration of volatile-rich mafic melt in lower crustal peridotites provokes deep earthquakes, initiates km scale shearzones and volatile transfer from the lower crust to the atmosphere
Autor: Bjørn Eske Sørensen, Eric James Ryan, Rune Larsen, Thomas Grant
We provide here in situ evidence from a network of well-preserved extensional shear zones cutting a rift related lower crustal Reinfjord Ultramafic Complex, Seiland Igneous Province, that formed in the late Ediacaran. Our results can explain seismic

Constraints upon fault zone properties by combined structural analysis of virtual outcrop models and discrete fracture network modelling
Autor: Marco Antonellini, Eric James Ryan, Giulia Tartaglia, Alberto Ceccato, Giulio Viola
The permeability structure of a fault zone is strongly dependent on the occurrence of meso-scale fracture patterns within the damage zone. Here, structural analyses of Virtual Outcrop Models (VOM) integrated with Discrete Fracture Network (DFN) model

Syn‐orogenic exhumation of high‐P units by upward extrusion in an accretionary wedge: Insights from the Eastern Elba nappe stack (Northern Apennines, Italy)
Autor: Giovanni Musumeci, Bjørn Eske Sørensen, Giulio Viola, Francesco Mazzarini, Espen Torgersen, Morgan Ganerød, Eric James Ryan, Samuele Papeschi
The E-vergent Northern Apennines formed by Oligocene-Miocene convergence and westward subduction of Adria beneath Europe. Extension ensued in the Mid-Late Miocene reflecting lower plate roll-back and causing opening of the back-arc Northern Tyrrhenia

In-situ petrophysical and geomechanical characterization and 3D modelling of a mature normal fault zone (Goddo fault, Bømlo – Norway)
Autor: Alberto Ceccato, Giulio Viola, Marco Antonellini, Eric James Ryan, Giulia Tartaglia
The detailed characterization of internal fault zone architecture and petrophysical and geomechanical properties of fault rocks is fundamental to understanding the flow and mechanical behaviour of mature fault zones. The Goddo normal fault (Bømlo

High‐P (P = 1.5–1.8 GPa) blueschist from Elba: Implications for underthrusting and exhumation of continental units in the Northern Apennines
Autor: Giulio Viola, Hans-Joachim Massonne, Francesco Mazzarini, Samuele Papeschi, Giovanni Musumeci, Eric James Ryan
The Acquadolce Subunit on the Island of Elba, Italy, records blueschist facies met- amorphism related to the Oligocene–early Miocene stages of continental collision in the Northern Apennines. The blueschist facies metamorphism is represented by gla

In situ evidence of earthquakes near the crust mantle boundary initiated by mantle co2 fluxing and reaction-driven strain softening
Autor: Eric James Ryan, Bjørn Eske Sørensen, Thomas B. Grant, Rune B. Larsen
Publikováno v: Earth and Planetary Science Letters
This study aims to understand the process behind the worldwide connection between deep crustal/upper mantle earthquakes and CO2 emissions along faults in rift zones. We do this by studying CO2-induced mineral reactions that facilitate strain localiza
