This study presents new zircon U–Pb ages, Sr–Nd–Hf isotopic data, and whole‐rock geochemical data obtained from the Early Cretaceous volcanic rocks from the north‐western Great Xing'an Range, Northeast China, to constrain the late Mesozoic magmatism and geodynamic setting of this region, which is located in the eastern segment of the Central Asian Orogenic Belt (CAOB). Zircon U–Pb age determinations...
This paper presents new zircon laser ablation–inductively coupled plasma–mass spectrometry U–Pb age and whole‐rock geochemical data for the high‐Nb basalts‐andesites (HNBs) from the Meiletu Formation in NE China. In comparison with common arc basalts and Nb‐enriched basalts, the Meiletu HNBs (140 Ma) show high TiO2 (1.7–3.2 wt.%), P2O5 (0.7–1.7 wt.%), Nb (14.6–34.0 ppm), and Zr (314–600 ppm) contents,...
