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.

Modeling of the Arabian/Nubian shield’s geothermal structure: a multi-parametric analysis using geophysical and geological tools [PDF]
Scientific ReportsThe Arabian-Nubian Shield (ANS) is a complex Neoproterozoic tectonic mosaic whose lithospheric structure and geothermal regime remain poorly constrained.

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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.
