We review the geochemical observations of water, D/H$\mbox{D}/\mbox{H}$ and volatile element abundances of the inner Solar System bodies, Mercury, Venus, the Moon, and Mars. We focus primarily on the inventories of water in these bodies, but also consider other volatiles when they can inform us about water. For Mercury, we have no data for internal water, but the reducing nature of the surface of Mercury would suggest that some hydrogen may be retained in its core. We evaluate the current knowledge and understanding of venusian water and volatiles and conclude that the venusian mantle was likely endowed with as much water as Earth of which it retains a small but non-negligible fraction. Estimates of the abundance of the Moon’s internal water vary from Earth-like to one to two orders of magnitude more depleted. Cl, K, and Zn isotope anomalies for lunar samples argue that the giant impact left a unique geochemical fingerprint on the Moon, but not the Earth. For Mars, an early magma ocean likely generated a thick crust; this combined with a lack of crustal recycling mechanisms would have led to early isolation of the Martian mantle from later delivery of water and volatiles from surface reservoirs or late accretion. The abundance estimates of Martian mantle water are similar to those of the terrestrial mantle, suggesting some similarities in the water and volatile inventories for the terrestrial planets and the Moon.

水星、金星、月球和火星的水和挥发性物质清单

我们回顾了水、D/H$\mbox{D}/\mbox{H}$ 和内太阳系天体、水星、金星、月球和火星的挥发性元素丰度的地球化学观测。我们主要关注这些身体中的水库存，但也会考虑其他可以告知我们水的挥发物。对于水星，我们没有内部水的数据，但水星表面的还原性质表明，一些氢可能保留在其核心中。我们评估了目前对金星水和挥发物的知识和理解，并得出结论，金星地幔可能含有与地球一样多的水，其中保留了一小部分但不可忽略的部分。对月球内部水丰度的估计从与地球相似到更耗尽一到两个数量级不等。氯，K，月球样本的 Zn 同位素异常认为，巨大的撞击在月球上留下了独特的地球化学指纹，但在地球上没有。对于火星来说，早期的岩浆海洋很可能产生了厚厚的地壳；这与地壳循环机制的缺乏相结合，将导致火星地幔早期与地表水库的水和挥发物的输送或晚期增生分离。火星地幔水的丰度估计与陆地地幔的丰度估计值相似，这表明类地行星和月球的水和挥发性存量存在一些相似之处。这与地壳循环机制的缺乏相结合，将导致火星地幔早期与地表水库的水和挥发物的输送或晚期增生分离。火星地幔水的丰度估计与陆地地幔的丰度估计值相似，这表明类地行星和月球的水和挥发性存量存在一些相似之处。这与地壳循环机制的缺乏相结合，将导致火星地幔早期与地表水库的水和挥发物的输送或晚期增生分离。火星地幔水的丰度估计与陆地地幔的丰度估计值相似，这表明类地行星和月球的水和挥发性存量存在一些相似之处。
