Geochemical constraints on the nature of Late Archean basaltic-andesitic magmatism in the North China Craton
X Wang, WB Zhu, YF Zheng - Earth-Science Reviews, 2022 - Elsevier
Abstract The North China Craton (NCC) is distinguished from the majority of Archean
cratons in the world by its extensive records of late Neoarchean (2.6–2.5 Ga) mafic …

Post-caldera volcanism reveals shallow priming of an intra-ocean arc andesitic caldera: Hunga volcano, Tonga, SW Pacific
Intra-oceanic arcs are typically associated with intermediate (andesitic) cone volcanoes.
However, caldera volcanoes may also form in these settings from very large eruptions …
