Analysis of Location of Villages in Relation to Rupture Zone (Case Study: North Qazvin Fault) [PDF]

open access: yesمسکن و محیط روستا, 2021
This paper studies the shear zone of North Qazvin fault and investigates the location of rural settlements in this area. In selected sections, the presence of transverse valleys along the fault made it possible to investigate the evidence of shear zones ...

Snell's Law for Shear Zone Refraction in Granular Materials [PDF]

open access: yesPhys. Rev. Lett. 103, 108301 (2009), 2009
We present experiments on slow shear flow in a split-bottom linear shear cell, filled with layered granular materials. Shearing through two different materials separated by a flat material boundary is shown to give narrow shear zones, which refract at the material boundary in accordance with Snell's law in optics.

An analytic interface dynamo over a shear layer of finite depth [PDF]

open access: yes, 2010
Parker's analytic Cartesian interface dynamo is generalized to the case of a shear layer of finite thickness and low resistivity ("tachocline"), bounded by a perfect conductor ("radiative zone") on the one side, and by a highly diffusive medium ...

THE ANALYSIS OF THE STRAIN STATE OF SHEAR ZONES IN TERMS OF  TYPES OF SECONDARY FRACTURES: STATEMENT OF PROBLEM

open access: yesГеодинамика и тектонофизика, 2015
Introduction. In this publication, shear zones, being traditional objects of tectonophysical studies, are considered in terms of their strain states. This approach differs from a commonly applied one when shear zones are studied with consideration of ...

The Capo Castello Shear Zone (Eastern Elba Island): Deformation at the Contact between Oceanic and Continent Tectonic Units

open access: yesGeosciences, 2020
Low-grade mylonitic shear zones are commonly characterized by strain partitioning, with alternating low strain protomylonite and high strain mylonite and ultramylonite, where the shearing is most significant. In this paper the capo Castello shear zone is

Shear Zones in granular materials: Optimization in a self-organized random potential [PDF]

open access: yesPhys. Rev. E 75, 011305 (2007), 2006
We introduce a model to describe the wide shear zones observed in modified Couette cell experiments with granular material. The model is a generalization of the recently proposed approach based on a variational principle. The instantaneous shear band is identified with the surface that minimizes the dissipation in a random potential that is biased by ...

Geochronology of shear zones – A review

open access: yesEarth-Science Reviews, 2018
Abstract Shear zones play a major role in the deformation of the crust at a variety of scales, as expressions of strain localization during orogeny and rifting, and also as reactivated structures. They influence the geometry and evolution of orogenic belts and rifts, crustal rheology, magma ascent and emplacement, and fluid flow.

The internal structure and composition of a plate-boundary-scale serpentinite shear zone: the Livingstone Fault, New Zealand [PDF]

open access: yesSolid Earth, 2019
Deciphering the internal structure and composition of large serpentinite-dominated shear zones will lead to an improved understanding of the rheology of the lithosphere in a range of tectonic settings.

Evolution of a shear zone before, during and after melting [PDF]

open access: yes, 2020
Partial melt in the deforming mid- or lower continental crust causes a strength decrease and drives formation of lithological heterogeneities. However, mechanisms of formation of syn-melt deformation zones and strain partitioning in partially molten rock

Deformation in the Greiner Shear Zone ̶ Pfitsch Valley, Southwestern Tauern Window [PDF]

open access: yes, 2023
The Greiner Shear Zone is located within the Subpenninic core of the southwestern Tauern Window, Eastern Alps. It strikes SW-NE and separates the upright folded Zillertaler and Tuxer Zentralgneis Nappes from one another, whilst transecting their ...
