REE mineralization age and geodynamic setting of the Huanglongpu deposit in the East Qinling orogen, China: Evidence from mineralogy, U–Pb geochronology, and in-situ Nd isotope

•The Huanglongpu deposit developed two stages of REE mineralization (219.4 Ma and 145.9–142.6 Ma).•The early REE mineralization is intimately related to the carbonatite Mo mineralization, which was created in the late Triassic post-collision extensional environment.•The late REE mineralization may be generated by REE remobilization and recrystallization resulting from the Yanshanian magmtism.•The REE mineralization that occurred at 145.9–142.6 Ma was first reported in the Qinling Region.
