Origin and Age of Magmatism in the Northern Philippine Sea Basins
Geochemistry, Geophysics, Geosystems, 2022 A Robust tectonic reconstruction of the Philippine Sea Plate around ∼52 Ma is a prerequisite in understanding the process of subduction initiation and establishment of the Izu‐Bonin‐Mariana arc.

Oxygen-isotope and trace element constraints on the origins of silica-rich melts in the subarc mantle [PDF]
, 2007 Peridotitic xenoliths in basaltic andesites from Batan island in the Luzon arc contain silica-rich (broadly dacitic) hydrous melt inclusions that were likely trapped when these rocks were within the upper mantle wedge underlying the arc.

Tiny droplets of ocean island basalts unveil Earth’s deep chlorine cycle
Nature Communications, 2019 Volatile exchange between the Earth’s interior and surface layers is one of the central issues in mantle geochemistry. Here the authors present evidence that chlorine is transferred from the surface to the deep mantle by subducted oceanic crust, forming ...

Deep Drilling into a Mantle Plume Volcano: The Hawaii Scientific Drilling Project [PDF]
Scientific Drilling, 2009 Oceanic volcanoes formed by mantle plumes, such as those of Hawaii and Iceland, strongly influence our views about the deep Earth (Morgan, 1971; Sleep, 2006).

Mantle heterogeneity during the formation of the North Atlantic Igneous Province: Constraints from trace element and Sr-Nd-Os-O isotope systematics of Baffin Island picrites [PDF]
, 2004 Sr-Nd-Os-O isotope and major and trace element data from ~62 Ma picrites from Baffin Island constrain the composition of mantle sources sampled at the inception of North Atlantic Igneous Province (NAIP) magmatism.

Crustal structure and rift flank uplift of the Adare Trough, Antarctica [PDF]
, 2005 The Adare Trough, located 100 km northeast of Cape Adare, Antarctica, represents the extinct third arm of a Tertiary spreading ridge between East and West Antarctica. It is characterized by pronounced asymmetric rift flanks elevated up to over 2 km above

The mantle isotopic printer: Basic mantle plume geochemistry for seismologists and geodynamicists [PDF]
, 2015 High-temperature geochemistry combined with igneous petrology is an essential tool to infer the conditions of magma generation and evolution in the Earth's interior. During the past thirty years, a large number of geochemical models of the Earth, essentially inferred from the isotopic composition of basaltic rocks, have been proposed. These geochemical

Oxygen isotope geochemistry of the second HSDP core [PDF]
, 2003 Oxygen isotope ratios were measured in olivine phenocrysts (~1 mm diameter), olivine microphenocrysts (generally ~100–200 µm diameter), glass, and/or matrix from 89 samples collected from depths down to 3079.7 m in the second, and main, HSDP core (HSDP-2)
