Vertical profiles of physicochemical and biodiversity data for the two tailings cores from the Fankou Pb/Zn mine located in Guangdong Province, P.R. China. The intermediate depth of each layer is taken as the depth of each sample. EC, electronic conductivity; TOC, total organic carbon; TP, total phosphorus; TS, total sulfur; vOTUs, the number of viral operational taxonomic units; OTUs, the number of prokaryotic operational taxonomic units
