Insights into the gold metallogeny of the Meguma terrane of Nova Scotia from LA-ICP-MS arsenopyrite geochemistry [PDF]

, 2018
International audienceThe time-space distribution of ore deposits in regards to the evolution of geological terranes is known as metallogeny. In the case of the Phanerozoic Meguma terrane of southern Nova Scotia, the origin of its classic slate-belt ...

Poleward Shift of Arctic Oceanic CO2 Uptake From Asymmetric Seasonal Changes Under Climate Warming

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract The Arctic region plays a disproportionate role in the global carbon cycle by acting as a critical sink for atmospheric CO2. However, how Arctic air‐sea CO2 fluxes will respond to continued warming regarding their spatial and temporal changes remains poorly understood.

Rapid Slab Rollback Drives Early Cretaceous Back‐Arc Extension in NE China: Implication for Crustal Growth and Episodic Porphyry Mineralization

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The subduction of the Paleo‐Pacific Plate beneath the NE Asian continental margin induced extensive magmatism, providing an excellent opportunity to investigate the interplay between plate dynamics, arc magmatism, continental crust formation, and porphyry mineralization.

Impacts of Coastal Underground Brine Exploitation on the Depletion of Shallow Brine in Beach and Neritic Zones

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Coastal underground brine (CUB) exploitation and groundwater discharge jointly drive the depletion of beach and neritic shallow underground brine (BNSUB). BNSUB is crucial for CUB exploitation, yet its reserve remain unquantified, and the impacts of different mining models on its evolution are poorly understood.

Unraveling the Enrichment Mechanisms of Rare Earth Elements in Deep‐Sea Sediments: An Environmental Magnetic Perspective

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Deep‐sea rare earth elements and yttrium (REY)‐rich sediments have attracted considerable attention since their discovery in 2011. However, the environmental factors controlling REY enrichment remain poorly understood, largely because paleoceanographic proxies are absent in pelagic clays.

Evolution and Provenance of the Polish Rotliegend in the Southern Permian Basin

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The Southern Permian Basin (SPB) has been extensively explored for ore deposits. However, a comprehensive evaluation of the remaining copper potential, specifically for sediment‐hosted stratiform copper system, remains lacking. This study applies goSPL, an open‐source landscape and stratigraphic evolution model, to reconstruct the Permian rift‐

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.

Depositional patterns constrained by slope topography changes on seamounts

Scientific Reports, 2020
Slope topography is known to control the spatial distribution of deposits on intraplate seamounts; however, relatively little is known about how slope topography changes constrain those depositional patterns.
