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

Mesoscopic response mechanism of shear surface roughness and residual strength in gravelly sliding zone soils

Yantu gongcheng xuebao, 2021
The mechanical properties of the gravelly sliding zone soils are closely related to the meso-structure of the shear surface. The quantitative characterization of shear surface roughness is of great significance to revealing the meso-mechanism of change ...

Zircon dissolution in a ductile shear zone, Monte Rosa granite gneiss, northern Italy [PDF]

, 2008
The sizes, distributions and shapes of zircon grains within variably deformed granite gneiss from the western Alps have been studied. Zircon shows numerous indicators of a metamorphic response in both the host gneiss and a 5 cm wide continuous ductile ...

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

Геодинамика 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 ...

Influence of the Tachocline on Solar Evolution [PDF]

, 2000
Recently helioseismic observations have revealed the presence of a shear layer at the base of the convective zone related to the transition from differential rotation in the convection zone to almost uniform rotation in the radiative interior, the ...

Variations in the P‐T‐t of Deformation in a Crustal‐Scale Shear Zone in Metagranite

Geochemistry, Geophysics, Geosystems, 2020
Deformation in crustal‐scale shear zones occurs over a range of pressure‐temperature‐time (P‐T‐t) conditions, both because they may be vertically extensive structures that simultaneously affect material from the lower crust to the surface, and because ...
