3D Quantification of Subsidence During Pyrenean Retro‐Wedge Initiation: Role of Structural and Thermal Inheritance on Hyperextended Margin Inversion (Aquitaine Basin)

Terra Nova, Volume 38, Issue 2, Page 130-140, April 2026.
ABSTRACT We present novel 3D subsidence data enabling vertical movements' quantification during the early formation of the Pyrenean retro‐wedge. From Cenomanian to Turonian times, subsidence is relatively low (~26 ± 10 m/Myr), corresponding to a brief 10 Myr thermal re‐equilibration of the European lithosphere following the hyperextended rift episode ...

De los tesauros a los topic maps: nuevo estándar para la representación y la organización de la información

Encontros Bibli, 2004
El sustantivo crecimiento del número de tesauros no ha servido para responder a la necesidad de trabajar en entornos multidisciplinares. Para responder a esta situación, se fomentó, en un primer momento, la fusión de tesauros con objeto de adaptar los ...

Contribution of the Rheologically Weak Lower Crust to Contemporary Crustal Motions in the Southeastern Tibetan Plateau, China

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The southeastern Tibetan Plateau (SETP) plays a pivotal role in accommodating intra‐continental deformation driven by the ongoing India‐Eurasia convergence. However, its contemporary surface vertical motions and the underlying geodynamic processes remain highly debated.

Numerical Modeling of Purely Active (Plume‐Produced) Continental Rifting and Break‐Up

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract In contrast to the traditional mechanism of passive continental rifting (driven by far‐field tectonic forces), the active rifting‐to‐break‐up processes (caused by rising mantle plumes) are still poorly understood. However, most episodes of fragmentation of the last supercontinent Pangea were relatively shortly preceded (within ∼10 Myr) by the ...

Heat and Tectonics of the Canadian Cordillera From the Seismically Constrained Inversion of Gravity Data

Tectonics, Volume 45, Issue 2, February 2026.
Abstract An updated approach to seismically constrained modeling of gravity data reveals two broad, NW‐trending low‐density zones in the mantle lithosphere beneath the Canadian Cordillera. The low‐density zones coincide with a shallow lithosphere‐asthenosphere boundary (LAB), a shallow Curie‐point depth, and the location of Quaternary volcanoes.

A Seismically Active Shear Zone in the Uppermost Mantle Beneath the Canadian Rockies

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Continental mantle earthquakes are uncommon but hold important clues for understanding lithospheric rheology. Few of these earthquakes (<10) have been documented in western North America, though it is likely more exist owing to difficulties in resolving focal depth for small earthquakes.

Linking Geodetically Resolved Uplift to Long‐Term Orogenic Exhumation in the Southern Alps, New Zealand

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract A limitation in our understanding of the geodynamics of orogenies is the difficulty in resolving the spatial variations in long‐term processes such as exhumation of the crust. Although geodesy can record ground motions to millimeter‐scale precision at high spatial and temporal resolutions, these observations only cover a small fraction of the ...

Evolução teórica sobre tesauro

Scire: representación y organización del conocimiento, 2020
Estudo de la evolución teórica acerca de los tesauros según el discurso del investigador Dagobert Soergel. Los tesauros son instrumentos de control de vocabulario, representación y recuperación de la información, utilizados en la indización. El reto fue de analizar el discurso de Soergel en sus artículos sobre la construcción, funciones, mantenimiento,

Desambiguação de relações em tesauros e o seu reúso em ontologias

Ciência da Informação, 2017
Um tesauro é composto de conceitos organizados por uma rede paradigmática (relações essenciais e estáveis entre termos e conceitos), e uma rede sintagmática (relações específicas em um contexto de uso).

Secular Evolution of the Seismic Structure of Continental Crust, Archean to Present

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract We summarize the seismic and density structure of continental crust as a function of crustal age and evaluate the secular changes in these physical properties. We subdivide the continental crust into six age provinces, from Archean to Mesozoic‐Cenozoic, and calculate the surface area, mean crustal thickness, volume, mass, and seismic velocity ...
