TLDR
In this paper, microprobe measurements of the concentrations of H2O, CO2, F, S and Cl and the isotopic composition of hydrogen are reported for populations of olivine-hosted melt inclusions from five lava samples from the Hawaiian volcanoes Loihi, Kilauea, Mauna Loa and Koolau.About:

An olivine-free mantle source of Hawaiian shield basalts
Alexander V. Sobolev,Albrecht W. Hofmann,Stephan V. Sobolev,Igor K. Nikogosian,Igor K. Nikogosian +4 more
TL;DR: Modelling shows that more than half of Hawaiian magmas formed during the past 1 Myr came from a deep olivine-bearing source, and the proportion of recycled (oceanic) crust varies from 30 per cent near the plume centre to insignificant levels at the plumes edge.
Volatiles in subduction zone magmas : concentration and fluxes based on melt inclusion and volcanic gas data
TL;DR: In this paper, the fluxes of volatiles subducted back into the mantle along subduction zones and returned from the mantle to the surface reservoir via magmatism suggests that there is an approximate balance for structurally bound H2O and Cl.

Vapour undersaturation in primitive mid-ocean-ridge basalt and the volatile content of Earth's upper mantle
TL;DR: The undersaturated pre-eruptive volatile content for a suite of mid-ocean-ridge basalts from the Siqueiros intra-transform spreading centre is reported, leading to correlations between volatiles and refractory trace elements that provide new constraints on volatile abundances and their behaviour in the upper mantle.

Sampling mantle heterogeneity through oceanic basalts: Isotopes and trace elements
TL;DR: Hofmann et al. as discussed by the authors reviewed the recent advances in the field of mantle geology, geophysics, and geochemistry using seismic mantle tomography, and concluded that the established views of the mantle being engaged in simple two-or single-layer convection are becoming obsolete.

Water in the oceanic upper mantle: implications for rheology, melt extraction and the evolution of the lithosphere
Greg Hirth,David L. Kohlstedt +1 more
TL;DR: In this paper, the influence of water on the dynamics of the oceanic upper mantle is re-evaluated based on recent experimental constraints on the solubility of water in mantle minerals and earlier experimental studies of olivine rheology.

Source regions and timescales for the delivery of water to the Earth
Alessandro Morbidelli,John Chambers,Jonathan I. Lunine,J. M. Petit,F. Robert,Giovanni B. Valsecchi,K. E. Cyr +6 more
TL;DR: In this paper, the authors investigated the origin of Earth's water of dynamical models of primordial evolution of solar system bodies and check them with respect to chemical constraints, finding that it is plausible that the Earth accreted water all along its formation, from early phases when the solar nebula was still present to the late stages of gas-free sweepup of scattered planetesimals.

An Experimental Study of Water and Carbon Dioxide Solubilities in Mid-Ocean Ridge Basaltic Liquids. Part I: Calibration and Solubility Models
TL;DR: In this paper, the authors used IR spectroscopy to determine the solubilities of H2O and CO_2 and the nature of their mixing behavior in basaltic liquid at pressures and temperature relevant to seqfloor eruption.

Hydrogen isotope fractionation between OH-bearing minerals and water
Tetsuro Suzuoki,Samuel Epstein +1 more
TL;DR: For the mica-water and amphibole-water systems, the hydrogen isotope fractionation factor was determined at temperatures ranging between 400 and 850°C as mentioned in this paper, where m is the molar fraction of the six-fold coordinated cations in the crystal, regardless of mineral species.

Primordial neon, helium, and hydrogen in oceanic basalts
Harmon Craig,John E. Lupton +1 more
TL;DR: A primordial neon component in neon from Kilauea Volcano and deep-sea tholeiite glass has been identified by the presence of excess 20Ne; relative to atmospheric neon the 20Ne enrichments are 54% in Kilea neon and about 25% in the basalts The 20Ne anomalies are associated with high 3He/4He ratios.
