Data for feldspar elemental and Pb isotope analyses from altered pegmatites in the North China Craton

This dataset provides the source data underlying the graphs and charts in a manuscript accepted in Communications Earth & Environment on fluid-driven element mobility and isotopic resetting in feldspars from altered pegmatites of the North China Craton. The data include in situ elemental concentrations and isotope ratios measured in plagioclase and potassium feldspar.
