资源简介：
This dataset contains pyrite EPMA geochemical analyses from the Zhongtiao meta-sedimentary rock-hosted Cu-Co deposits in Shanxi Province, China, along with density functional theory (DFT) calculation results on pyrite. It supports our study on fluid-induced solid-state diffusion and critical metal enrichment in sulfides.
