Transient conduit permeability controlled by a shift between compactant shear and dilatant rupture at Unzen volcano (Japan) [PDF]

Solid Earth, 2022
The permeability of magma in volcanic conduits controls the fluid flow and pore pressure development that regulates gas emissions and the style of volcanic eruptions.

Strain Partitioning along Terrane Bounding and Intraterrane Shear Zones: Constraints from a Long-Lived Transpressional System in West Gondwana (Ribeira Belt, Brazil)

Lithosphere, 2022
Shear zones are zones of localized high strain accommodating differential motion in the lithosphere and impacting the crustal rheology and deformational history of orogenic belts.

Effects of grain shape on packing and dilatancy of sheared granular materials [PDF]

, 2014
Granular material exposed to shear shows a variety of unique phenomena: Reynolds dilatancy, positional order and orientational order effects may compete in the shear zone. We study granular packings consisting of macroscopic prolate, oblate and spherical

San-in shear zone in southwest Japan, revealed by GNSS observations

Earth, Planets and Space, 2017
A right-lateral shear zone in the San-in region, southwest Japan, has been proposed by previous geological and seismological studies. It locates 350 km north of the Nankai Trough, that is, the main plate boundary between the subducting Philippine Sea and

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

, 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 ...

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

مسکن 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 ...

Shear Strength Characteristics of Clay-Gravel Layer and Its Slope Failure Law and Mechanism

Frontiers in Earth Science, 2022
The Anqing Formation clay-gravel layer is widely distributed in the Anqing area of the upper reaches of the Wanjiang River. It is a typical soil-rock mixture composed of gravel and clay.

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

Geosciences, 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

Late Ediacaran lateral-escape tectonics as recorded by the Patos shear zone (Borborema Province, NE Brazil)

Brazilian Journal of Geology, 2021
Lateral escape tectonics mediated by strike-slip fault zones are an efficient mechanism of rock deformation in the continental crust of collision zones.

Rate dependent shear bands in a shear transformation zone model of amorphous solids [PDF]

, 2008
We use Shear Transformation Zone (STZ) theory to develop a deformation map for amorphous solids as a function of the imposed shear rate and initial material preparation.
