Seismic evidence for melt-rich lithosphere-asthenosphere boundary beneath young slab at Cascadia [PDF]
Nature CommunicationsThe Lithosphere-Asthenosphere Boundary (LAB) beneath oceanic plates is generally imaged as a sharp seismic velocity reduction, suggesting the presence of partial melts.

Volcanism and long-term seismicity controlled by plume-induced plate thinning [PDF]
Nature CommunicationsMantle plumes, the hot upwellings from the Earth’s core-mantle boundary, are thought to trigger surface uplift and the emplacement of large igneous provinces (LIPs). Magmatic centres of many LIPs are scattered over thousands of kilometres.

A local lithospheric structure model for Vietnam derived from a high-resolution gravimetric geoid
Earth, Planets and Space, 2021 High-resolution Moho and lithosphere–asthenosphere boundary depth models for Vietnam and its surrounding areas are determined based on a recently released geoid model constructed from surface and satellite gravity data (GEOID_LSC_C model) and on 3ʹʹ ...

Lithospheric Structure of the Circum‐Pannonian Region Imaged by S‐To‐P Receiver Functions
Geochemistry, Geophysics, Geosystems, 2023 The lithosphere‐asthenosphere boundary and mid‐lithospheric discontinuities are primary attributes of the upper mantle. The Pannonian region is an extensional sedimentary basin enclosed by collisional orogens.

Discovery of flat seismic reflections in the mantle beneath the young Juan de Fuca Plate
Nature Communications, 2020 Applying seismic imaging methods on ocean bottom hydrophone data, the authors here describe a horizontal, flat lithosphere base plus lithosphere-asthenosphere boundary beneath the young (0.51 to 2.67 Ma) Juan de Fuca plate.

The lithosphere-asthenosphere boundary observed with USArray receiver functions [PDF]
Solid Earth, 2012 The dense deployment of seismic stations so far in the western half of the United States within the USArray project provides the opportunity to study in greater detail the structure of the lithosphere-asthenosphere system.

Global distribution of the lithosphere-asthenosphere boundary: a new look [PDF]
Solid Earth, 2012 New global maps of the depth to the boundary between the lithosphere and the asthenosphere are presented. The maps are based on updated global databases for heat flow and crustal structure.

Frontiers in Earth Science, 2023 It is essential to investigate the spatial distribution of the lithosphere and asthenosphere in detail, to further obtain the understanding of the effect of plate collision and the process of orogenic movement.
