Variations in the isotopic ratios of volatile elements in different reservoirs on the terrestrial planets carry information about processes that operated on the planets since their formation. Comparisons between primordial planetary compositions, to the extent they can be determined, may help us understand the planetary formation process. This working group report summarizes our knowledge of terrestrial planet volatile inventories.
