Metallogeny and Genesis of Fault-Filling Barite-Sulfide Veins (Ougnat, Morocco): Petrography, Fluid Inclusion, and Sr-S Isotopic Constraints

Géosciences
The Ougnat Massif of the eastern Anti-Atlas (Morocco) hosts barite and sulfide vein-type deposits of vital economic importance. With over 150 mineralized structures reported in the Ougnat Massif, the ore-bearing ones are predominantly composed of barite,

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‐

Divergent drift of Adriatic-Dinaridic and Moesian carbonate platforms during the rifting phase witnessed by triassic MVT Pb-Zn and SEDEX deposits; a metallogenic approach [PDF]

, 2016
Early-intracontinental rifting of Pangea is result of thermal doming in Uppermost Permian time giving rise to the formation of horst-graben  structures, followed by slow subsidence, marine transgression and evaporate deposition.

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.
