Petrochemical and petrophysical characterization of the lower crust and the Moho beneath the West African Craton, based on Xenoliths from Kimberlites [PDF]
Additional evidence to the composition of the lower crust and uppermost mantle was presented in the form of xenolith data. Xenoliths from the 2.7-Ga West African Craton indicate that the Moho beneath this shield is a chemically and physically gradational

Update Heat Flow Density Map for Portugal [PDF]
, 2010 New thermal conductivity, heat production and temperature data obtained in Portugal were used to produce a new heat flow density map. Heat flow density values in Portugal vary between 42 and 115 mW/m2 and allow the extrapolation of temperatures to depths

Seismic wide-angle study of accreted Proterozoic crust in southeastern Wyoming [PDF]
, 1994 A seismic wide-angle xperiment was conducted in southeastern Wyoming, USA to investigate the seismic character of a postulated Proterozoic magmatic arc south of the suture (Cheyenne Belt) to the Archean Wyoming Province.

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract The Northeastern (NE) Tibet, as the front of plateau growth, widely absorbs northeastward extrusion, leading to significant uplift and forming a basin‐mountain tectonic framework. However, it remains unclear how the crust of NE Tibet deformed in response to the far‐field effects of the India‐Eurasia collision.

Are there superposed Mohos in the south-western Alps? New seismic data from fan-profiling reflections [PDF]
, 2007 International audienceThe Moho preserves imprints of the regional geodynamic evolution of the lithosphere. As such, its detailed topography in divergence or convergence zones has a strong bearing on any geodynamic model. This is still more critical where

Moho Depth Variations in Central Italy
, 2013 [1] Along the Italian peninsula adjoin two crustal domains, peri-Tyrrhenian and Adriatic, whose boundary is not univocal in central Italy. In this area, we attempt to map the extent of the Moho in the two terrains from variations of the travel time difference between the direct P wave and the P-to-S wave converted at the crust-mantle boundary, called ...

Ambient‐Noise Multicomponent Multimodal Dispersion Characteristics in Thick Sedimentary Basins
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Ambient noise cross‐correlations enable the extraction of multimodal surface waves, yet resolving their complex dispersion characteristics is essential for robust subsurface imaging. Using dense array data from the North China Plain, we resolve multicomponent multimodal Rayleigh and Love wave dispersion with unprecedented detail.

Convergent flow in a two-layer system and mountain building [PDF]
, 2010 With the purpose of modelling the process of mountain building, we investigate the evolution of the ridge produced by the convergent motion of a system consisting of two layers of liquids that differ in density and viscosity to simulate the crust and the
