abstract = "At present, reported data for Re-PGE mass fractions (in particular) and 187Os/188Os isotope ratios of organic-rich reference materials (RMs) are rare, hampering the comparison of data quality between different laboratories. In this study, we measured the Re-PGE (Os, Ir, Ru, Pt and Pd) mass fractions, as well as 187Os/188Os isotope ratios of five shale RMs, including USGS SGR-1b (oil shale), SBC-1 (marine shale), SCo-2 (silty marine shale), ShTX-1 (calcareous organic-rich shale) and ShCX-1 (calcareous shale), and one oil RM, NIST RM 8505. The results show that the five shale RMs have similar upper continental crust-normalised PGE-Re patterns and are generally homogeneous in Re-PGE mass fractions and 187Os/188Os isotope ratios at test portions of 0.2–0.5 g, and thus can be used as matrix-matched RMs for Re-Os and PGE of shale samples. The oil RM NIST 8505 and its asphaltene separates are also roughly homogeneous in Re-PGE mass fractions and 187Os/188Os isotope ratios at test portions of 0.1–0.3 g and can potentially be used as an oil RM for Re-Os and PGE.",
