The data set contains mass fraction data for siderophile volatile (Cu, Se, Ag, S, Te, Cd, In, and Tl), highly siderophile (Ir, Ru, Pt, Pd), and, for reference, refractory lithophile elements (Ba and Sm) analyzed from the same digestion aliquot by isotope dilution-inductively coupled plasma mass spectrometry, following the methods described in Wang et al. (2015, https://doi.org/10.1111/j.1751-908X.2014.00312.x). We analyzed 13 high-Ti mare basalt samples collected at the Apollo 11 and 17 landing sites. Additionally, we report highly siderophile element data for 3 high-Ti mare basalt samples analyzed in Gleißner et al. (2022, https://doi.org/10.1016/j.epsl.2022.117680). All samples were allocated by NASA/JSC and analyzed in the Geochemistry Laboratories at Freie Universität Berlin, Germany.
