Decomposition of the elastic tensor and geophysical applications

JT Browaeys, S Chevrot - Geophysical Journal International, 2004 - academic.oup.com
Elasticity is described in general by a fourth-order tensor with 21 independent coefficients,
which corresponds to the triclinic symmetry class. However seismological observations are …

Constraints on the evolution and vertical coherency of deformation in the Northern Aegean from a comparison of geodetic, geologic and seismologic data

C Kreemer, N Chamot-Rooke, X Le Pichon - Earth and Planetary Science …, 2004 - Elsevier
We study the 3-D strain evolution of the northern Aegean and the vertical coherency of
deformation. We observe that finite strain orientations in the mantle inferred from published …

Mantle deformation during slow seafloor spreading constrained by observations of seismic anisotropy in the western Atlantic

JB Gaherty, D Lizarralde, JA Collins, G Hirth… - Earth and Planetary …, 2004 - Elsevier
During mantle flow at mid-ocean ridges, viscous shear deformation imparts a structural
fabric that remains in the lithosphere as it cools, preserving a record of ridge processes over …

Upper mantle S-wave speed heterogeneity and anisotropy beneath the North Atlantic from regional surface wave tomography: the Iceland and Azores plumes

S Pilidou, K Priestley, O Gudmundsson… - Geophysical Journal …, 2004 - academic.oup.com
We present a high-resolution Sv-wave velocity and azimuthal anisotropy model for the upper
mantle beneath the North Atlantic and surrounding region derived from the analysis of over …

Strain modelling, seismic anisotropy and coupling at strike-slip boundaries: Applications in New Zealand and the San Andreas fault

MK Savage, KM Fischer, CE Hall - Geological Society, London …, 2004 - lyellcollection.org
Despite similar surface transform faulting behaviour, observed shear-wave splitting patterns
in the California and New Zealand plate boundary regions are markedly different. To better …
