Abstract Hawaiian volcanoes record 6 Ma of potentially deep mantle chemistry and form two parallel volcanic chains that are geochemically unique, named Loa and Kea. Loa volcanoes erupt lavas with isotopically enriched compositions thought to reflect

Effusive eruptions dominate the eruptive record of many arc volcanoes and may hold crucial information about their plumbing systems, yet they are underrepresented in geochemical and petrological studies. Here, we present whole rock major and trace el

Abstract International Ocean Discovery Program Expedition 352 to the Izu‐Bonin forearc cored over 800 m of basement comprising boninite and boninite‐series lavas. This is the most extensive, well‐constrained suite of boninite series lavas ever

The Popocatépetl Volcanic Complex (PVC) is an active arc volcano located in central Mexico, 70 km southeast of Mexico City. Current models of the PVC’s plumbing system and magma petrogenesis are largely based on studies of isolated Plinian eruptio

Volatiles expelled from subducted plates melt the overlying warm mantle, feeding arc volcanism. However, debates continue over the factors controlling melt generation and transport and how these determine the placement of volcanoes. To broaden our sy

Following the Indian-Asian continental collision, the Tibetan Plateau experienced continuous magmatism from south to north, most of which is characterized by high potassium (K) content and negative niobium‑tantalum‑titanium (Nb-Ta-Ti) anomalies.

Rhenium (Re) is a redox-sensitive element. Recent advances in the precision of measurement of the stable isotopic composition of Re (δ187Re) allow exploration of its potential as a proxy for paleoredox and/or chemical weathering [1]. However, as yet

Lavas from the 2021 Fagradalsfjall eruption, Iceland, show remarkable, day to month scale temporal variations in trace element and radiogenic isotopic compositions. Changes have been attributed to variation in the depth and degree of melting and/or s

Volcanic arc lavas often carry mushy rocks from deeper levels of magma plumbing systems, termed “plutonic xenoliths”, to the surface. These xenoliths offer the opportunity to study magma evolution in the crust. Here we focus on the Lesser Antille

Plate tectonics requires the formation of plate boundaries. Particularly important is the enigmatic initiation of subduction: the sliding of one plate below the other, and the primary driver of plate tectonics. A continuous, in situ record of subduct
