Trace element and isotopic data of the Yunmengshan iron formation collected from the Daimeishan section in the North China Craton

This database includes the mineral analysis and the isotopic analysis of the seven IF samples. The combined trace element data, negative δ56Fe while positive δ53Cr values reveal terrestrial precipitation of Fe without long-distance transport and an enhanced continental oxidative weathering at the end of Paleoproterozoic with increased atmospheric oxygen.
