The distinction betwween Sn-mineralized and Sn-barren granites in Sn isotopes

This dataset contains Sn isotope compositions for a suite of granite samples from the Xiaoxiong and Yanbei complex . The data includes Sample IDs and the corresponding δ122/118Sn values (relative to NIST SRM 3161a) with 2 standard deviation (2SD) uncertainties. The data were produced to investigate the potential of Sn isotopes as a discriminator between mineralized and barren granites. All Sn isotope ratios were measured using MC-ICP-MS at State Key Laboratory of Critical Earth Material Cycling and Mineral Deposits, School of Earth Sciences and Engineering, Nanjing University.
