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

open access: yesEarth, 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

Evidence from Rb–Sr mineral ages for multiple orogenic events in the Caledonides of Shetland, Scotland [PDF]

open access: yes, 2015
Shetland occupies a unique central location within the North Atlantic Caledonides. Thirty-three new high-precision Rb–Sr mineral ages indicate a polyorogenic history.

Load transfer mechanism and critical length of anchorage zone for anchor bolt.

open access: yesPLoS ONE, 2020
The length of anchorage zone of an anchor bolt affects the distribution of axial force and shear stress therein. Based on a shear-displacement model, the load distribution of anchor bolts in the elastic deformation stage was analysed.

PALEOPROTEROZOIC TECTONICS AND EVOLUTIONARY MODEL OF THE ONEGA SYNCLINORIUM

open access: yesГеодинамика и тектонофизика, 2023
Consideration is being given to the Onega Paleoproterozoic structure (Onega synclinorium, OS) as a tectonotype of intraplate negative structures, which experience intermittent subsidence over a long period of time.

S wave velocity structure below central Mexico using high-resolution surface wave tomography [PDF]

open access: yes, 2010
Shear wave velocity of the crust below central Mexico is estimated using surface wave dispersion measurements from regional earthquakes recorded on a dense, 500 km long linear seismic network.

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 ...

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

open access: yesBrazilian 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.
