U-Pb, major, and trace element data of zircon, garnet, biotite, and plagioclase from the Bengbu uplift area, Northern China v.3

Guided by reviewer comments, this version (v.3) further revises the dataset by: 1) adding the melt reintegration data presented in Table S5; and 2) correcting labeling errors in Fig. S2, enlarging the axes and text, and improving image clarity. These revisions enhance the presentation and completeness of the dataset, providing a more robust foundation for petrogenetic and tectonic interpretations.
