The data was sourced from project 2020YFA0714802 and tested at the National Research Center for Geoanalysis. International standard reference material samples were dissolved via Carius tube isotope dilution method, followed by chemical pretreatment, before individual elements were measured separately. Re was analyzed using multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS), Os using thermal ionization mass spectrometry (TIMS), and PGE using Agilent 8900 ICP-MS/MS. Re isotope ratio standard solutions were employed, and the Sample Standard Bracketing (SSB) method was applied to correct for mass fractionation of Re isotope ratios obtained by MC-ICP-MS. National standard reference material JCBY was used to conduct full-workflow monitoring of Re-Os isotope data. Internal laboratory monitoring solutions, including the std-series elemental standard solutions and PGE mixed standard solutions, were utilized to monitor and correct for interfering elements and isobars in PGE data acquired by ICP-MS/MS. All data errors are reported as 2σ. This dataset has broad application prospects and considerable academic and practical value: Firstly, it provides calibration benchmarks for global geological analysis laboratories, which can be used to verify the accuracy and repeatability of Re-Os isotope dating and PGE content testing methods, supporting the establishment of laboratory quality control systems. Secondly, it facilitates cross-regional and cross-institutional data comparison and integration. The unified data reference of international standard reference materials can break technical barriers among different research teams, promoting collaborative research in fields such as global magmatic evolution and mineral resource genesis. Thirdly, it promotes the standardization of analytical methods and technology popularization, providing core data support for formulating Re-Os/PGE analytical standard methods in China's geological experimental testing industry, and helping domestic technologies align with international standards.
