报告内容：The Moon is thought to have been covered by a deep magma ocean shortly after its formation. Full crystallization of a Lunar Magma Ocean (LMO) has been modeled numerically on the basis of a small subset of experiments in the classic work of Snyder et al. (1992). A recent experimental study focused on partial LMO solidification (Elardo et al., 2011). Since ~2008, however, the traditional view of a dry Moon (Taylor et al., 2006) has been challenged by the identification of water in lunar pyroclastic glasses (Saal et al., 2008, 2013), lunar minerals including apatite (e.g., Saal et al., 2013; McCubbin et al., 2010a,b; Boyce et al., 2010; Greenwood et al., 2011; Hui et al., 2013; Tartese et al., 2013, 2014; Barnes et al., 2014, 2016) and melt inclusions in lunar olivine (Saal et al., 2013; Hauri et al., 2011; Chen et al., 2015). Water could therefore play an important role in the evolution of the Moon, including perhaps during the cooling and crystallization of an early lunar magma ocean (LMO). Water has been shown to greatly affect the physical and chemical properties of minerals and magmas, even at low concentrations (Sisson and Grove, 1993). Therefore, the presence of significant amounts of water in the ancient lunar interior requires a reassessment of lunar evolution models.
The aim of this work is to discuss the dry and wet LMO evolution with solidification and quantify water content in the early Moon based on high-pressure high-temperature experiments.
