Scale-dependent influence of pre-existing basement shear zones on rift faulting : a case study from NE Brazil [PDF]

open access: yes, 2013
Rifting of continental crust initiates faults that are commonly influenced by pre-existing structures. We document newly identified faults cutting Precambrian units in the interior of the NE Brazilian margin to assess the effects of structural ...

Universal and wide shear zones in granular bulk flow [PDF]

open access: yes, 2004
We present experiments on slow granular flows in a modified (split-bottomed) Couette geometry in which wide and tunable shear zones are created away from the sidewalls.

Structural and hydrogeological features of Pleistocene shear zones in the area of Rome (Central Italy)

open access: yesAnnals of Geophysics, 1994
The last tectonic episode observed in the Latium Tyrrhenian margin (Central Italy), few km cast of Rome, is represented by a set of middIe-upper Pleistocene N-S shear zones, characterised by complex geometric and kinematic setting.

The Orivesi granite batholith, Southern Central Finland - characteristics and emplacement [PDF]

open access: yesBulletin of the Geological Society of Finland, 1996
The Orivesi granite batholith is situated in an E-W trending belt of granite intrusions along the southern margin of the Central Finland Granitoid Complex (CFGC).

Structure and tectonic significance of high- and low-temperature deformation along the lateral escape-related Guaçuí and Batatal shear zones, southern Araçuaí Orogen (southeastern Brazil)

open access: yesREM: International Engineering Journal, 2020
The Guacuí and Batatal lineaments in the southern region of the state of Espírito Santo (southeastern Brazil) can be traced from satellite images for tens of kilometers.

PT-conditions of deformation within the Palaeoproterozoic South Finland shear zone: Some geothermobarometric results [PDF]

open access: yesBulletin of the Geological Society of Finland, 2005
Four rock samples were collected from the crustal-scale South Finland shear zone in order to compare PT-conditions of deformation between gneissose and mylonitic rock types.

Timanian Fold-and-Thrust Belt and Caledonian Overprint in the Selis Ridge Imaged by New 3D Seismic Attributes and Spectral Decomposition

open access: yesTektonika, 2023
The present study is a detailed structural analysis of 3D seismic data in the Selis Ridge in the western Loppa High in the Norwegian Barents Sea, to which new seismic attributes and spectral decomposition were applied.

Distribution, characteristics, ages, and tectonic environments of ductile shear zones in the Beishan orogenic belt

open access: yesDizhi lixue xuebao
Objective  The Beishan occupies a pivotal position between the eastern and western segments of the Central Asian Orogenic Belt (CAOB). Although numerous ductile shear zones have been identified in this area, they have received limited attention, leading ...

Timing of Palaeoproterozoic crustal shearing in the central Fennoscandian Shield according to U-Pb data from associated granitoids, Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 2001
Granitoids in the Finnish part of the Fennoscandian Shield were created by numerous Archaean and Palaeoproterozoic tectonic events. Late phases of Palaeoproterozoic, Svecokarelian deformation created ductile, crustal-scale shear zones, of which the N-S ...

Cooperative Shear Model for the Rheology of Glass-Forming Metallic Liquids [PDF]

open access: yes, 2006
A rheological law based on the concept of cooperatively sheared flow zones is presented, in which the effective thermodynamic state variable controlling flow is identified to be the isoconfigurational shear modulus of the liquid.
