The oxygen isotope composition of diogenites: Evidence for early global melting on a single, compositionally diverse, HED parent body

Oxygen isotope measurements of a suite of 22 diogenites demonstrate that they have a restricted range of Δ17O values: −0.246±0.014(2σ). These results indicate that the diogenites form a single population consistent with a single parent body source, rather than multiple sources as has recently been s...
