Assessing the Helium Potential of Variscan Batholiths: Insight From Corsica Island
Geochemistry, Geophysics, GeosystemsMost of the current helium (He) reserves originate from fortuitous discoveries, mainly made during oil and gas exploration in sedimentary basins. As helium generation depends on U and Th α‐decay, old geological provinces gather key ingredients for high ...

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Post-collisional batholiths do contribute to continental growth [PDF]
, 2023 Post-collisional voluminous silicic magmatism is represented in most orogens across the world in the form of large granodiorite batholiths and minor intermediate and mafic intrusions, postdating 5-30 Ma the age of the collisional paroxysm responsible of ...

Petrogenesis and Tectonic Implication of Jurassic Granites in Central Guangdong, SE China: Constraints from Zircon U-Pb-Hf-O and Whole-Rock Geochemical and Sr-Nd Isotopic Data [PDF]
LithosphereThe origin and tectonic regime responsible for the inland Jurassic granites in Southeast (SE) China remain controversial. This study presents zircon secondary ion mass spectrometry (SIMS) U-Pb ages, in situ zircon Hf-O isotopes, and whole-rock ...

Geosciences, 2018 The Archaean (4.0–2.5 Ga) continental crust is mainly composed of granitoids, whose geochemical characteristics are a function of their formation mechanisms and components, as well as physical conditions of their source.

Generation of magmatism under active continental margins: A thermodynamic study of subduction and translithospheric diapirs [PDF]
, 2022 A recent model of continental arc magmatism states that subducted sediments mix physically with the oceanic slab basalts in the subduction channel and produce diapirs that ascend through the mantle wedge, undergo melting and relaminate to the base of the
