  1. CC, carbonaceous chondrite; EC, enstatite chondrites; OC, ordinary chondrites.
  2. Data for bulk H2O and bulk H-isotopic compositions of CC and unequilibrated OC meteorites (weighted averages from ref. 11), equilibrated OCs and ECs from ref. 55, and average bulk N and bulk N-isotopic composition53,59 of chondritic materials. s.d. is the standard deviation of literature data for given chondrite types.
  3. *Single data points from Alexander et al.11 uncertainties represent analytical errors.
