U and Th content in the Central Apennines continental crust: a contribution to the determination of the geo-neutrinos flux at LNGS

, 2011
The regional contribution to the geo-neutrino signal at Gran Sasso National Laboratory (LNGS) was determined based on a detailed geological, geochemical and geophysical study of the region.

Nature of the Crust in the Superdeep Bengal Basin Using Teleseismic P Waves

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Bengal Basin is a sedimentary basin in the northeast region of the Indian subcontinent. It lies between the Indian Shield and the Indo‐Burma Ranges, where the India plate is obliquely subducting under the Burma microplate. Multiple interpretations of the nature of the crust here have been proposed.

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

Plate Interactions and Mantle Flows Beneath the Caribbean and Adjacent Regions Revealed by P‐Wave Anisotropic Tomography

Tectonics, Volume 45, Issue 3, March 2026.
Abstract We determine the first P‐wave azimuthal and radial anisotropy tomography beneath the Caribbean and its adjacent regions. The Cocos and Atlantic Plates are imaged as high‐velocity (high‐V) zones down to ∼1,600 km depth and they have subducted independently beneath the Caribbean Plate.

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

Crustal structure below Popocat\'epetl Volcano (Mexico) from analysis of Rayleigh waves [PDF]

, 2007
An array of ten broadband stations was installed on the Popocat\'epetl volcano (Mexico) for five months between October 2002 and February 2003. 26 regional and teleseismic earthquakes were selected and filtered in the frequency time domain to extract the

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 ...

Thick Crust at Earth's Slowest Spreading Ridge: 3D Gravity Insights From Eurasian Basin, Arctic Ocean

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The Eurasian Basin of the Arctic Ocean opened by ultraslow spreading along the Gakkel Ridge, yet crustal thickness has remained poorly constrained due to sparse seismic data. We present a new basin‐wide 3‐D gravity model, updated by the most comprehensive sediment thickness and seismic observations, offering the first systematic view of ...

Tectonic evolution of a continental collision zone: A thermomechanical numerical model [PDF]

, 2004
We model evolution of a continent-continent collision and draw some parallels with the tectonic evolution of the Himalaya. We use a large-scale visco-plasto-elastic thermomechanical model that has a free upper surface, accounts for erosion and deposition

The effective elastic thickness of the India Plate from receiver function imaging, gravity anomalies and thermomechanical modelling [PDF]

, 2006
The range and the meaning of the effective elastic thickness (EET) in continental areas have been subject to controversy over the last two decades. Here we take advantage of the new data set from the Hi-CLIMB seismological experiment to re-estimate the ...
