The volatile history of the Moon is challenging to reconstruct, and current petrological evidence is somewhat contradictory in terms of the Moon's mantle being water-rich or water-poor1-3. Key to understanding this history is the volcanic activity that we know shaped the Moon's surface and provided an efficient volatile outgassing mechanism. New quantification of the H2O and CO content of lunar magmas can be provided by assessing lunar mass eruption rates through comparison with eruption processes constrained by geomorphological studies of eruption deposits on the Moon's surface. This overall information can then be used in magma ascent models, adapted for lunar conditions, to determine volatile contents of magmas which are consistent with observed pyroclastic deposits. These new insights will shed light on the evolution of volatiles in the Moon, the distribution of volatiles between the Earth and the Moon, and provide new constraints on the processes which modify the interior and atmosphere of Solar System bodies

月球动荡的历史很难重建，目前的岩石学证据在月球地幔是富水还是贫水方面有些矛盾1 -3。了解这段历史的关键是火山活动，我们知道火山活动塑造了月球的表面，并提供了一个有效的挥发性放气机制。通过与月球表面喷发沉积物地貌研究所限制的喷发过程进行比较，评估月球大规模喷发率，可以提供月球岩浆中H2O和CO含量的新的量化数据。这一整体信息，然后可以用于岩浆上升模型，适用于月球的条件，以确定挥发性成分的岩浆是一致的观察到的火山碎屑沉积物。这些新的见解将阐明月球挥发物的演变，地球和月球之间挥发物的分布，并对改变太阳系天体内部和大气的过程提供新的限制
