Dynamic evolution of changbaishan volcanism in Northeast China illuminated by machine learning

Frontiers in Earth Science, 2023
Previous studies propose that there is a mantle upwelling that generated the Cenozoic basalts in Changbaishan. However, the dominant source and mechanism of the mantle upwelling remains highly debated.

Transient deformations in the Suez-Sinai area from GPS observations [PDF]

, 2005
We analyze data from four GPS campaigns carried out between 1997 and 2002 on a network of 11 sites in the Suez-Sinai, the area of collision between the African and the Arabian plates.

Crustal Responses to the Destruction of Continental Lithosphere: Insights From Radial Anisotropy of the Tanlu Fault Zone, Eastern China

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Since the Mesozoic, much of the eastern China lithosphere was removed through thermo‐mechanical erosion and delamination, yet the effects on the overlying crust remain unclear. The Tanlu Fault Zone (TLFZ), the region's largest lithosphere‐scale weakness, offers a natural laboratory to assess crustal responses to lithospheric destruction.

New Constraints on the Calabrian Arc (Central Mediterranean) Geodynamics: High‐Resolution Imaging of Lithospheric and Upper Mantle Discontinuities From P and S Receiver Functions

Geophysical Research Letters
The Calabrian Arc subduction system (Central Mediterranean) is characterized by a deep and narrow (200 km) slab. Addressing the poorly understood link between shallow and deep mantle structures, we present the first high‐resolution mapping of crustal and

Shear-Wave Splitting and Mantle Flow Beneath the Colorado Plateau and its Boundary with the Great Basin [PDF]

, 2008
Shear-wave splitting measurements from SKS and SKKS phases show fast polarization azimuths that are subparallel to North American absolute plate motion within the central Rio Grande Rift (RGR) and Colorado Plateau (CP) through to the western rim of the ...

Lithosphere, asthenosphere, and perisphere [PDF]

Reviews of Geophysics, 1995
“Lithosphere” is a mechanical concept implying strength and relative permanence. Unfortunately, the term has also been applied to the surface thermal boundary layer (TBL) and a shallow enriched geochemical reservoir, features having nothing to do with strength. The “strong” lithosphere is about one half the thickness of the TBL.

Seismic Imaging Reveals Ongoing Modification of Craton Margins in Northeast Asia

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Cratonic margins are commonly modified, yet the processes responsible remain debated. The Korean Peninsula, situated between adjacent cratons, the Japan Trench, and a back‐arc system, provides a natural setting to investigate this problem. Using 4 years of dense seismic observations, we image upper‐mantle structure beneath the peninsula with P‐

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.

Resistivity Structure of the Alabama‐Oklahoma Lineament and Mississippi Embayment: Insights Into Crustal Weakness, Heat Flow, and Seismicity of the Region

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract The Alabama–Oklahoma Lineament (AOL) is a major crustal boundary that intersects the Mississippi Embayment (ME) and may influence intraplate deformation in the southern United States. We present the first regional magnetotelluric (MT) resistivity models across the AOL–ME system using EarthScope data and two‐dimensional inversion. All southwest–
