Cerium isotope fractionation during carbonatite-related rare earth element mineralization: Insights from the Weishan and Longbaoshan deposits, North China Craton

This dataset includes: (1) whole-rock major and trace element data for one Longbaoshan alkaline rock sample, three glimmerite-type ore bodies, and two aegiapite-type ore bodies from the Longbaoshan REE deposit; (2) a total of 12 calcite C–O isotope analyses from glimmerite-type and aegiapite-type ore bodies, limestone from Longbaoshan, and igneous carbonatite from the Weishan deposit; (3) a total of 15 whole-rock Ce isotope analyses from alkaline rocks, glimmerite, aegiapite, igneous carbonatite from Weishan, and limestone from Longbaoshan. In addition, the dataset contains a binary mixing model calculation of Ce isotopes between igneous carbonatite and surface limestone from Longbaoshan.
