Description

This dataset supports the study of the Roozaori porphyry Cu deposit, Eastern Kunlun Orogen, NW China. It contains analyses of zircon and apatite from three drill-core samples that represent magmatic (23ZK01-8, fresh granite porphyry), transitional (23ZK01-4, altered magmatic breccia), and hydrothermal (23ZK01-1, vein material) stages. The data are in one Excel file with five tables: • Table S1: Electron microprobe (EPMA) data for apatite: SiO₂, P, CaO, F, Cl and calculated OH, plus Ti, Sr, Y and Nb (20 analyses per stage). • Table S2: LA-ICP-MS U–Pb isotopic data and concordia ages for zircon (Plešovice primary standard; 91500, Tanz and ZS secondary standards). • Table S3: LA-ICP-MS U–Pb isotopic data and lower-intercept ages for apatite (MAD2 primary standard; McClure Mountain and Kovdor secondary standards; common-Pb corrected). • Table S4: LA-ICP-MS trace-element data for zircon (80 analyses) and apatite (110 analyses), including REE, Hf, Ta, ΣREE, Ce/Ce* and Eu/Eu*. It also holds derived ratios (Sr/Y, Th/U, (La/Yb)N and others), Ti-in-zircon temperatures, and ΔFMQ oxygen fugacity estimates. • Table S5: Summary statistics (n, min, max, mean, median) of porphyry Cu fertility indicators by stage, compared with global thresholds. All analyses were done at Yanduzhongshi Geological Analysis Laboratories Ltd., Beijing, China. EPMA used a JEOL JXA-8230. LA-ICP-MS used a 193 nm NWR193 ArF excimer laser with an Analytik Jena PlasmaQuant MS. Data were reduced with ICPMSDataCal, and ages were calculated with Isoplot v.4.15. Uncertainties are 2σ unless stated otherwise. Concentrations are in μg/g unless stated otherwise, and ages are in Ma. Derived columns and Table S5 are calculated by formula from the raw data in Table S4.
