Volatile History of the Moon

月球不稳定的历史很难重建，目前的岩石学证据在月球地幔富水或贫水方面有些矛盾1-3。理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表面，并提供了一种有效的挥发性放气机制。通过与月球表面喷发沉积的地貌研究所限制的喷发过程进行比较，通过评估月球质量喷发速率，可以提供新的月球岩浆H2O和CO含量的量化。然后，这些总体信息可以用于适应月球条件的岩浆上升模型，以确定与观测到的火山碎屑沉积相一致的岩浆的挥发分含量。这些新的见解将揭示月球中挥发分的演化，地球和月球之间的挥发分分布，并为改变太阳系天体内部和大气的过程提供新的约束

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
