Geology of the Susa Shear Zone (Susa Valley, Western Alps) [PDF]

Journal of Maps, 2020
The 1:10,000 scale geological map of the Susa Shear Zone (SSZ) in the inner sector of the Western Alps, aims to describe the geological setting and tectonic evolution of a first-order Alpine shear zone, which drove exhumation and juxtaposition of ...

Microzonation of the Linares, Northeast Mexico area, based on geology and shear-wave velocity measurements [PDF]

Geofísica Internacional, 2005
We determined the velocity structure of S-wave (VS), P-wave (VP) and the average shear velocity to 30 meters depth (Vs30) at 30 locations in the Linares, Nuevo León area. VS and VP measurements were made from seismic refraction profiles.

Using Passing Trains as Seismic Sources for Refraction Microtremor Site Characterisation Surveys: Rugeley, Staffordshire, UK

Iraqi Geological Journal, 2023
Microtremor seismic surveys are routinely used to provide shear wave velocities that are converted to soil stiffness site profiles. In this paper, we look to assess the feasibility of using trains as seismic sources to characterize near-surface ...

Fuzzy set concept in structural geology: Example of ductile simple shear

Journal of Earth System Science, 2021
Much of the time, geological data are not accurately known. Instead, geoscientists work with a range of possible data. These data can have a range since they can vary spatially and temporally. In this context, we demonstrate how a well-established structural geological model of velocity profile of ductile simple shear, expressed as an equation, can be ...

Connecting shear localization with the long-range correlated polarized stress fields in granular materials

Nature Communications, 2020
Understanding the behavior of jammed granular matter is important for a range of phenomena, from materials science to geology. Wang et al. uncover relations between stress correlations and emergence of localized shear bands due to external shear stress ...
