The chlorine isotope fingerprint of the lunar magma ocean.
The Moon contains chlorine that is isotopically unlike that of any other body yet studied in the Solar System, an observation that has been interpreted to support traditional models of the formation of a nominally hydrogen-free ("dry") Moon. We have analyzed abundances and isotopic compositions of Cl and H in lunar mare basalts, and find little evidence that anhydrous lava outgassing was import...
متن کاملUnderstanding the Chlorine Isotopic Composition of Apatites in Lunar Basalts
Introduction: On Earth δCl = ~0 ± 5 ‰ [1]. For lunar rocks elevated δCl values of up to 35 ‰ have been reported in apatites [1,2]. The initial study interpreted the elevated δCl in lunar rocks as a result of metal chlorides degassing in low-H2O environments [1]. Additional data [3,4] have shown high-δCl values in samples with apatite containing appreciable amounts of H2O (>2000 ppm). Metasomati...

متن کاملHigh pre-eruptive water contents preserved in lunar melt inclusions.
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 eruption, did...
متن کاملWater in lunar anorthosites and evidence for a wet early Moon
The Moon was thought to be anhydrous since the Apollo era1, but this view has been challenged by detections of water on the lunar surface2–4 and in volcanic rocks5–9 and regolith10. Part of this water is thought to have been brought through solarwind implantation2–4,7,10 and meteorite impacts2,3,7,11, long after the primary lunar crust formed from the cooling magma ocean12,13. Here we show that...
