The crustal magmatic structure beneath the Denali Volcanic Gap imaged by a dense linear seismic array

S Rabade, FC Lin, C Tape, KM Ward… - Journal of …, 2023 - Wiley Online Library
The crustal structure in south‐central Alaska has been influenced by terrane accretion, flat
slab subduction, and a modern strike‐slip fault system. Within the active subduction system …

Melt network reorientation and crystallographic preferred orientation development in sheared partially molten rocks

C Seltzer, M Peč, ME Zimmerman… - Geochemistry …, 2023 - Wiley Online Library
We investigated the co‐evolution of melt, shape, and crystallographic preferred orientations

Seismic response of a mid-story isolated stilted structure in mountainous areas

J Li, D Liu - PloS one, 2024 - journals.plos.org
Research on the SSI effect on flat sites has yielded many valuable conclusions. However,
current research on the impacts of various special local terrains on structural dynamics …

Melt organisation and strain partitioning in the lower crust

AL Lee, T Torvela, GE Lloyd, AM Walker - Journal of Structural Geology, 2018 - Elsevier
Partial melts can form as a result of crustal thickening due to orogenesis. Even small melt
fractions weaken the crust, so that partially molten volumes should accumulate significant …

Rayleigh wave attenuation and amplification measured at ocean‐bottom seismometer arrays using Helmholtz tomography

JB Russell, CA Dalton - Journal of Geophysical Research: Solid …, 2022 - Wiley Online Library
Shear attenuation provides insights into the physical and chemical state of the upper mantle.

Evolution of a shear zone before, during and after melting

AL Lee, GE Lloyd, T Torvela… - Journal of the Geological …, 2020 - lyellcollection.org
Partial melt in the deforming mid-or lower continental crust causes a strength decrease and
drives formation of lithological heterogeneities. However, mechanisms of formation of syn …

Deformation behavior and inferred seismic properties of tonalitic migmatites at the time of pre‐melting, partial melting, and post‐solidification

Y Shao, S Piazolo, Y Liu, AL Lee, W **… - Geochemistry …, 2021 - Wiley Online Library
As seismic data from the lower crust becomes more readily available, it is important to link
seismic properties to the ongoing processes within lower crustal evolution. This includes …
