Understanding seismic anisotropy in the Rotondo granite: investigating stress as a potential source [PDF]
Solid EarthThe hypothesis of stress-induced seismic anisotropy was tested in the Bedretto Lab, a deep underground rock laboratory in the Swiss Alps. Several comprehensive cross-hole seismic surveys were acquired to analyze the directional dependency of seismic-wave

Известия высших учебных заведений: Геология и разведка, 2022 Introduction. Reservoirs composed of thin layers with different elastic properties exhibit the anisotropy of elastic properties. Anisotropic environments are studied using special seismic positioning systems that require large financial and time ...

Multiscale modeling of upper mantle plasticity: From single-crystal rheology to multiphase aggregate deformation [PDF]
, 2014 We report a first application of an improved second-order (SO) viscoplastic self-consistent model for multiphase aggregates, applied to an olivine + diopside aggregate as analogue for a dry upper mantle peridotite deformed at 10 15 s 1 shear strain rate ...

Deriving micro- to macro-scale seismic velocities from ice-core c axis orientations [PDF]
The Cryosphere, 2018 One of the great challenges in glaciology is the ability to estimate the bulk ice anisotropy in ice sheets and glaciers, which is needed to improve our understanding of ice-sheet dynamics.

Implication of the lopsided growth for the viscosity of Earth's inner core [PDF]
, 2012 Two main seismic features characterize the Earth's inner core: a North-South polar anisotropy and an East-West asymmetry of P-wave velocity and attenuation. Anisotropy is expected if shear deformation is induced by convective motions.
