Accretion of Earth\u2019s volatiles:
\nIn terms of their H and N isotopes, as well as
\nvolatile element abundances, the CI and CM like
\nbodies are the most likely the sources of Earth\u2019s
\nvolatiles [5, 15]. Since the bulk H and N isotopic
\ncompositions of CI and CM chondrites probably
\nevolved during their aqueous alteration, the Earth\u2019s
\nbuilding blocks cannot have accreted them until after
\nalteration was complete, which was \u22654-5 Myr after
\nCAIs [13] and after Mars-sized embryos had begun
\nto form [28].<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
