Provenance and Petrological Evolution of Sand Injection Complexes: Insights From Heavy Mineral Analysis in the Paleogene Forearc Succession of the San Joaquin Basin

Basin Research, Volume 38, Issue 3, May–June 2026.
The study of heavy mineral assemblages with statistical analysis resolves provenance signatures and quantifies syn‐emplacement modification of sand injection complexes. Results demonstrate transformative petrological processes, including density‐dependent hydraulic sorting and mechanical grain degradation.

Tectonic Interplay in the Gulf of Cagliari (Italy): Extension, Compression and Strike‐Slip Movements

Basin Research, Volume 38, Issue 3, May–June 2026.
Since the Oligocene, extensional tectonics of the Sardinia Rift and Campidano Graben interacted with the collision between Sardinia and northern Africa, generating reverse faults. At the Plio‐Quaternary boundary, compressional tectonics resumed, shaping the southern margin of the gulf through transpressional tectonics of the exposed Ichnusa High ...

Timing of Metamorphism and Deformation in the Neoarchean Quetico Metasedimentary Belt, Superior Craton, Constrained by Garnet Trace‐Element Mapping and Lu–Hf Geochronology

Journal of Metamorphic Geology, Volume 44, Issue 4, Page 265-286, May 2026.
ABSTRACT The Quetico subprovince of the Superior Province is among the largest metasedimentary belts globally and provides evidence of tectonic processes at play during the final stages of Archean cratonization. Although previous studies have shown that deformation and metamorphism of the 2.7‐Ga turbiditic protolith resulted in regional subvertical ...

Epidote Records (De)hydration From the Seafloor Through Subduction and Underplating: Implications for Subduction Zone Fluid Budgets and Slow Slip

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract When, where, and how much fluid is released from subducting oceanic crust control deformation, element cycling, and magmatism in subduction zones. However, the palimpsest of tectonometamorphic processes in the exhumed rock record complicates the relation of geologic observations to geodynamic models of subduction fluid sources and transport ...

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

Sedimentology, Volume 73, Issue 3, Page 802-837, April 2026.
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.

~990 Ma peak granulitic metamorphism and amalgamation of Oaxaquia, Mexico: U–Pb zircon geochronological and common Pb isotopic data

Revista Mexicana de Ciencias Geológicas, 2018
The ~1 Ga Oaxacan Complex is the largest exposure of the Oaxaquia terrane of Mexico. Microprobe analysis of co-existing ortho- and clino-pyroxene, garnet, ilmenite and plagioclase indicate metamorphic conditions of 735 ± 5° C and 7.7 ± 0.1 kbar in the ...

Uranium-bearing metasediment and granite in the Tasermiut area, South Greenland

Rapport Grønlands Geologiske Undersøgelse, 1981
Regional exploration for uranium was carried out in South Greenland in 1979 and 1980. From the planning stage the area between the fjords Tasermiut and Søndre Sermilik (fig. 16) was considered a favourable target beeause uranium deposits from geological environments of similar age, strueture and lithology are known, e.g.
