Asymmetries in the Temporal Variation of the Electron Content During a Solar Eclipse

open access: yesEarth and Space Science, Volume 12, Issue 7, July 2025.
Abstract Solar eclipses offer a unique opportunity to study rapid variations in the Earth's atmosphere. By accurately modeling the timing and magnitude of obscuration caused by the Moon's shadow, we can investigate the eclipse's impact on the behavior of the Earth's ionosphere.

Funcionamiento hidrológico de un humedal ribereño, el Masegar, en el conjunto de los humedales de La Mancha Húmeda de la cuenca alta del rió Cigüela

open access: yesEstudios Geologicos, 1995
En 1981, a petición del Gobierno español, la UNESCO declaró Reserva de la Biosfera «La Mancha Húmeda». En 1995 la UNESCO ha indicado que este título puede ser retirado si continúa la degradación del conjunto de humedales que integran esa Reserva de la ...

Middle Pleistocene revelations: unravelling taphonomic processes in mammals including Mesotherium cristatum (Mesotheriidae, Notoungulata), Corralito Site, Córdoba Province, Argentina

open access: yesPalaeontology, Volume 68, Issue 4, July/August 2025.
Abstract Taphonomic studies of Cenozoic mammals are scarce. We report a study of the taphonomy of the Corralito site (Middle Pleistocene to Holocene), Córdoba Province, Argentina, which documents the last population of the South American native ungulate typotherid Mesotherium cristatum. We discovered two specimens of M.

Evidence for surface uplift of the Atlas Mountains and the surrounding peripheral plateaux: Combining apatite fission-track results and geomorphic indicators in the Western Moroccan Meseta (coastal Variscan Paleozoic basement) [PDF]

open access: yes, 2010
This work represents an initial attempt to link the evolution of the topography in relation to the general tectonic framework of western Morocco. For this purpose, in a section of the Western Moroccan Meseta different tools are combined in order to ...

Seismotectonics and Crustal Structure in the Southern Dominican Republic Offshore Margin: Implications on the Tsunami Potential

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract Many coastal areas of the southern Dominican Republic experience considerable population pressure accompanied by important economic activity. The southern offshore margin is characterized by significant seismicity and active geological processes.

Evolución paleoambiental del sector meridional del Parque Nacional de Doñana desde el Plioceno Inferior a la actualidad

open access: yesEstudios Geologicos, 2013
El estudio de los materiales geológicos y las asociaciones de ostrácodos presentes en un testigo largo obtenido en el sur del Parque Nacional de Doñana (SO de España) permite inferir una evolución paleoambiental desde medios marinos someros (Plioceno ...

Salt Diapirs and Minibasins Along a Transect Across the Basque‐Cantabrian Pyrenees: Implications for Cover‐Basement Interaction During Rifting and Inversion

open access: yesTectonics, Volume 44, Issue 5, May 2025.
Abstract The Basque‐Cantabrian Pyrenees experienced Early Cretaceous rifting and latest Cretaceous to Cenozoic inversion, with the presence of prerift Upper Triassic Keuper salt influencing how deformation was accommodated. Considerable disagreement exists on the degree of decoupling of supra‐ and subsalt deformation, the amount of thin‐skinned ...
