A numerical model for the gravimetric recovery of sub-lithospheric mantle structures

Geodesy and Geodynamics, 2020
It is a well-known fact that the long-wavelength terrestrial geoid undulations are mainly attributed to deep mantle density heterogeneities, while more detailed features in the geoid geometry are associated with the topography and the lithospheric ...

The Mantle Structure of North China Craton and Its Tectonic Implications: Insights from Teleseismic P-Wave Tomography

Journal of Marine Science and Engineering
To study the mantle structure of the North China Craton (NCC) and its tectonic implications, in particular, the evolution of the rift systems in the Trans-North China Orogen (TNCO), we used teleseismic data recorded by 250 portable seismic stations to ...

Cretaceous–Palaeogene Plate Boundary Evolution at the Pacific Margins of Zealandia and West Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Improved satellite‐derived gravity data support updated interpretations and models of ancient plate boundaries and plate motions affecting Zealandia and West Antarctica. The models combine to confidently resolve hundreds of kilometres of Late Cretaceous–Eocene motion between the Pacific and Lord Howe plates, confirming that plate circuit constructions ...

Structure and evolution of the intracratonic Congo Basin [PDF]

Surface wave tomography, heat flow, and crustal thickness measurements have demonstrated that the thickness of the continental lithosphere varies by at least a factor of 2. Since the thermal time constant of the lithosphere depends upon the square of its

Broadband Seismic Deployments for Imaging the Upper Mantle Structure in the Lützow-Holm Bay Region, East Antarctica

International Journal of Geophysics, 2011
Broadband seismic deployments have been carried out in the Lützow-Holm Bay region (LHB), Dronning Maud Land, East Antarctica. The recorded teleseismic and local events are of sufficient quality to image the structure and dynamics of the crust and mantle

Negative Residual Topography in Global Back‐Arc Basins Scales With Slab Dip

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Dynamic topography above subduction zones is widely inferred, but its magnitude and controls remain poorly constrained at the global scale. Here, we estimate residual topography across a range of back‐arc basins by correcting bathymetry for sediment loading, crustal structure, and lithospheric age, and compare the anomalies with slab geometry ...

Rheological control of Wadati-Benioff zone seismicity [PDF]

, 1988
Intermediate and deep focus earthquakes in Wadati-Benioff zones are thought to occur in the cold interiors of downgoing slabs which are significantly stronger than the warmer mantle.

Crustal fault reactivation facilitating lithospheric folding/buckling in the central Indian Ocean

, 1996
High-quality, normal-incidence seismic reflection data confirm that tectonic deformation in the central Indian Ocean occurs at two spatial scales: whole lithosphere folding with wavelengths varying between 100 and 300 km, and compressional reactivation ...

Thermal and petrophysical characterization of the lithospheric mantle along the northeastern Iberia geo-transect

, 2014
We present a new model on the present-day lithospheric structure along a 1100 km transect crossing the NE-Iberian Peninsula, the Western Mediterranean basin and the Algeria margin and ends at the Tell–Atlas Mountains.
