The making of pure quartzose sand in continental interiors: Paraná River (Brazil and Argentina)

Sedimentology, EarlyView.
ABSTRACT As part of a comprehensive project on sedimentary processes in South America, this study focuses on sediment generation in the intracratonic Paraná Basin and monitors the evolution of sand composition along the Paraná River from central Brazil to the Río de la Plata estuary in Argentina.

Research of ore elements migration forms in the hydrothermal solutions of the Mid-Atlantic ridge

Известия высших учебных заведений: Геология и разведка, 2016
On the basis of geological and hydrogeochemical analysis, the issue of forming of hydrothermal plumes in Atlantic Ocean is considered. Forms of the ore elements migration in hydrothermal solutions of the Logachev vent field (14°45' N) were researched ...

Catalogue of source mechanisms and overview of present-day stress fields in the western region of the Africa–Eurasia plate boundary

Frontiers in Earth Science
Complex deformation is observed along the plate boundary between the Africa and Eurasia plates, this complexity is highlighted by the faulting mechanism changing from normal faulting at the Mid-Atlantic Ridge to thrust and strike-slip faulting in the ...

Crustal Accretion, Significant Mantle Uplift, and Exhumation along Non-transform Discontinuities: Equatorial Mid-Atlantic Ridge (7º 10’ – 0º 50’ N)

Brazilian Journal of Geophysics
The exhumation and exposure of mantle rocks is a common process that takes place during the tectono-magmatic evolution of a newly created lithosphere along slow- and ultraslow-spreading oceanic ridges, such as the Equatorial Mid-Atlantic Ridge.

Black smokers on the Mid‐Atlantic Ridge

Eos, Transactions American Geophysical Union, 1985
Evidence for a variety of active hydrothermal venting phenomena, including black smokers, was discovered at a site on the Mid‐Atlantic Ridge by a research team of government and university scientists. The work was accomplished on a cruise of the National Oceanic and Atmospheric Administration (NOAA) ship Researcher during July 1985 as part of the NOAA ...

Mesoscale and Submesoscale Variability in the Indian Ocean

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Material transport and air‐sea coupling dynamics associated with monsoon‐related mesoscale and submesoscale processes in the Indian Ocean significantly modulate biogeochemical cycles, the large‐scale energy balance, and both regional and global climate change.

High‐Resolution Digital Terrain Model and Land‐Surface Parameters of São Sebastião and Ilhabela, Southeastern Brazil

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
The first openly accessible 2 m‐resolution lidar‐based DTM and an extensive set of land‐surface parameters (LSPs) for the region of São Sebastião and Ilhabela, southeastern Brazil, reveal geomorphological features previously indiscernible, including past landslide deposits, drainage captures and structural lineaments.

Hierarchical Testing of a Hybrid Machine Learning‐Physics Global Atmosphere Model

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Machine learning (ML)‐based models have demonstrated high skill and computational efficiency, often outperforming conventional physics‐based models in weather and subseasonal predictions. While prior studies have assessed their fidelity in capturing synoptic‐scale atmospheric dynamics, their performance across timescales and under out‐of ...

Isotope and trace element insights into heterogeneity of subridge mantle

Geochemistry, Geophysics, Geosystems, 2014
Geochemical data for abyssal peridotites are used to determine the relationship to mid‐ocean ridge basalts from several locations at ridge segments on the SW Indian Ridge (SWIR), the Mid‐Cayman‐Rise (MCR), and the Mid‐Atlantic Ridge (MAR).
