The data set contains concentration data for highly siderophile (Ir, Ru, Pt, Pd), siderophile volatile (Cu, Se, Ag, S, Te, Cd, In, and Tl) 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). We analyzed 12 low-Ti mare basalt samples collected at the Apollo 12 and 15 landing sites. Additionally we report highly siderophile element data for samples analyzed in Gleißner et al. (2022) for siderophile volatile elements. All samples were allocated by NASA/JSC and analyzed in the Geochemistry Laboratories at Freie Universität Berlin, Germany.</br> </br> Analysis period: 2019-2022
