Primitive magmatic melt inclusions from the Moon contain as much water as some terrestrial mid-ocean ridge magmas. The Moon has long been thought to be highly depleted in volatiles such as water, and indeed published direct measurements of water in lunar volcanic glasses have never exceeded 50 parts per million (ppm). Here, we report in situ measurements of water in lunar melt inclusions; these samples of primitive lunar magma, by virtue of being trapped within olivine crystals before volcanic… Expand
Hydrogen Isotopes in Lunar Volcanic Glasses and Melt Inclusions Reveal a Carbonaceous Chondrite Heritage
TLDR
Results demonstrate that lunar magmatic water has an isotopic composition that is indistinguishable from that of the bulk water in carbonaceous chondrites and similar to that of terrestrial water, implying a common origin for the water contained in the interiors of Earth and the Moon. Expand
Using lunar apatite to assess the volatile inventory of the Moon
Lunar petrology, most notably the absense of hydrous minerals (such as micas and amphiboles) and the lack of Fe 2 O 3 , imply a low oxygen activity for the Moon. The anhydrous nature of the Moon isExpand
A melt inclusion study on volatile abundances in the lunar mantle
Abstract Earth’s Moon was thought to be highly depleted in volatiles due to its formation by a giant impact. Over the last decade, however, evidence has been found in apatites, lunar volcanic glassExpand
Constraints on volatile concentrations of pre-eruptive lunar magma
Abstract Until recently, the Moon had long been thought to be depleted of volatiles such as H 2 O, S, CO x and Cl 2 . Researchers have recently measured volatile concentrations in the minerals,Expand
Preservation of primordial signatures of water in highly-shocked ancient lunar rocks
Abstract Spurred by the discovery of water in lunar volcanic glasses about a decade ago, the accessory mineral apatite became the primary target to investigate the abundance and source of lunarExpand
Water in the lunar interior
Presence and distribution of water and other volatiles in the lunar interior could have played a key role in the early evolution of the Moon. We report abundance of water along with F and Cl, inExpand
The lunar magma ocean volatile signature recorded in chlorine-rich glasses in KREEP basalts 15382 and 15386
Copyright © 2017 by The Geochemical Society of Japan. Earth. High volatile abundances in lunar samples are also problematic for our basic understanding of the Moon, such as its formation in a giantExpand
Large sulfur isotope fractionation in lunar volcanic glasses reveals the magmatic differentiation and degassing of the Moon
TLDR
The first in situ measurements of sulfur isotope ratios dissolved in primitive volcanic glasses and olivine-hosted melt inclusions recovered from the Moon by the Apollo 15 and 17 missions reveal large variations in 34S/32S ratios, which positively correlates with sulfur and titanium contents within and between the distinct compositional groups of volcanic glasses analyzed.

Water, fluorine, and sulfur concentrations in the lunar mantle
The concentrations of volatile elements in the moon have important implications for the formation of the earth–moon system. There is currently a debate regarding the water content of the lunarExpand
Late delivery of chondritic hydrogen into the lunar mantle: Insights from mare basalts
Recent analytical advances have enabled first successful in-situ detection of water (measured as OH) in lunar volcanic glasses, and, melt inclusions and minerals from mare basalts. These in-situExpand

Lunar apatite with terrestrial volatile abundances
TLDR
Quantitative ion microprobe measurements of late-stage apatite from lunar basalt 14053 are reported that document concentrations of H, Cl and S that are indistinguishable from apatites in common terrestrial igneous rocks, suggesting portions of the lunar mantle or crust are more volatile-rich than previously thought. Expand
Volatile content of lunar volcanic glasses and the presence of water in the Moon’s interior
TLDR
The results indicate that, contrary to prevailing ideas, the bulk Moon might not be entirely depleted in highly volatile elements, including water, and the presence of water must be considered in models constraining the Moon’s formation and its thermal and chemical evolution. Expand
Outgassed Water on Mars: Constraints from Melt Inclusions in SNC Meteorites
TLDR
Determination of the pre-eruptive water contents of SNC parental magmas from calculations of the solidification histories of these amphibole-bearing inclusions indicates that martian magmas commonly contained 1.4 percent water by weight, implying a wetter Mars interior than has been previously thought.

Volcanic Gas Formed During Eruption of Apollo 17 Orange Glass Magma; Evidence from Glassy Melt Inclusions and Experiments
Melt inclusions from Apollo 17 orange glass core samples (74001/2) have been studied in order to learn more about the pre-eruption melt. Small amounts of orange glass powder were heated at or nearExpand
The geochemistry of olivine-hosted melt inclusions in a FAMOUS basalt ALV519-4-1
Abstract Some 22 melt inclusions hosted by high-Mg olivines (Fo88–91) from a single basalt lava from the FAMOUS area of the Mid-Atlantic Ridge were analyzed for major and trace elements. The resultsExpand
Hydrogen isotopes in Mariana arc melt inclusions: Implications for subduction dehydration and the deep-Earth water cycle
Abstract Water is carried into Earth's mantle at subduction zones via hydrous mineral phases in subducting lithospheric plates. A certain fraction of this water is released during subduction andExpand
Deep pooling of low degree melts and volatile fluxes at the 85°E segment of the Gakkel Ridge: Evidence from olivine-hosted melt inclusions and glasses
Abstract We present new analyses of volatile, major, and trace elements for a suite of glasses and melt inclusions from the 85°E segment of the ultra-slow spreading Gakkel Ridge. Samples from thisExpand
Recycled dehydrated lithosphere observed in plume-influenced mid-ocean-ridge basalt
TLDR
It is demonstrated that basalts associated with mantle plume components containing subducted lithosphere—‘enriched-mantle’ or ‘EM-type’ basalts—contain less water than those associated with a common mantle source. Expand
Vapour undersaturation in primitive mid-ocean-ridge basalt and the volatile content of Earth's upper mantle
TLDR
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.

The Chlorine Isotope Composition of the Moon and Implications for an Anhydrous Mantle
TLDR
The chlorine isotope content of lunar samples returned by the Apollo missions is found to be 25-fold greater than for rocks and minerals that have been measured from Earth and meteorites, implying that the Moon’s water content is much lower than suggested by recent studies. Expand
