Extended Data Fig. 3: Reproducibility of hydrogen isotope analysis of the standards and the CE5 apatite and ilmenite-hosted melt inclusions over the analytical session.
From: A dry lunar mantle reservoir for young mare basalts of Chang’e-5
The reproducibility of δD analysis throughout the whole analytical sessions was ±43‰ (2σ), estimated on the Kovdor apatite standard. The average δD values measured for the SWIFT MORB glass and Durango apatite are −113 ± 109‰ and −92 ± 210‰, respectively, consistent with their recommended values29,57 within analytical errors. The average δD values measured for the basaltic glass standards 1833-11 and 519-4-1 are −101 ± 86‰ and −132 ± 158‰, respectively. All analytical data are listed in Extended Data Tables 3, 4, Supplementary Table 3.
