This is a corrigendum to Yang et al. (2017). There is a typo in the Fo (Mg-number) of the olivine sample. The Fo is defined as the molar ratio of Mg/(Mg+Fe). The chemical composition values listed in Table 1 are correct, but the calculated Fo# value should be 91. This has no effect on our results or conclusions. The revised table and paragraph are given below, with the revised parts highlighted in bold.

Samples
Olivine, a common mineral found in many meteorites and S-type asteroids (e.g., Chapman 1996, 2004), was used as the analog material in this work. Natural pure olivine granules collected from Hebei Province, China, were first ground into a size distribution of 0–75 μm with a vibratory disc mill (VDM). The olivine powders were then sieved and those smaller than 45 μm were separated out as the target sample. The chemical compositions of these olivine powders were analyzed using the wet chemistry method. To ensure that no contaminations were introduced during the grinding process, compositional measurements were made on both the original samples and the powders processed with the VDM. The major element contents of these two samples, as summarized in Table 1, indicate that the grinding process did not introduce any contaminations of iron, and the Mg number of the olivine sample is 91 (Fo91).
