Geologica Acta, 2018 In the Tafí del Valle region, in northwestern Argentina, several intrusive bodies of lower Paleozoic age were emplaced in the metasedimentary Puncoviscana Formation, belonging to the Sierras Pampeanas. Four intrusive bodies outcrop in the study area: La

Water Resources Research, Volume 62, Issue 6, June 2026.Abstract Interbasin groundwater flow (IGF) is increasingly recognized as an important but difficult‐to‐diagnose component of regional groundwater flow systems. Recent studies highlight that major rifts within the Yarlung Zangbo River Basin (YZRB) may facilitate IGF, but the role of all six major rifts remains unclear.

Sanukitoidsandthe origin of secondary I-type granites
, 2020 Goldschmidt (2020) Online, 21-26 June 2020[EN] I-type granitesare by far the most abundant in the crust. They form both the large Andean-type batholithsat active continental margins and the post-collisional batholiths that mostly ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract The cratonic lithospheric mantle records complex metasomatic processes and is frequently tapped by alkaline magmatism, offering a unique opportunity to trace the progressive evolution of the mantle. In the present contribution, we investigate a newly identified calc‐alkaline lamprophyre field from the Neoarchean Jonnagiri Schist Belt, Eastern ...

Late Devonian lamprophyric dykes in the Meguma Zone of Nova Scotia
, 1989 Hornblende-rich lamprophyric dykes from southeastern Nova Scotia are contemporaneous with the large peraluminous granitic batholiths (ca. 370 Ma) of the Meguma Zone and may be closely associated with their origin.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract The middle Cretaceous granitoid plutons of the Shalair Valley, situated in northeastern Iraq, constitute a principal magmatic component of the Sanandaj–Sirjan Zone within the northwestern segment of the Zagros Orogenic Belt. Among these plutons, the equigranular Aulan body (AG) and the porphyritic Laladar body (LG) were crystallized at 111.0 ±

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.Abstract Crust formed in volcanic arcs is accreted to continents over geologic time, serving as the source material for new continental crust in Earth's present and recent past. Geochemically, arcs are found to be significantly more mafic than bulk continental crust.
