Vanadium isotope data of bimodal volcanic rocks in the Hailar Basin, Northeast China

Description

This dataset contains vanadium isotope compositions (δ⁵¹V) and related geochemical data for bimodal volcanic rocks (basaltic trachyandesites and trachytes–rhyodacites) from the Hailar Basin, Northeast China. It is used to investigate vanadium isotope fractionation during the evolution of mafic and felsic magmas in intracontinental magmatic systems. The supplementary files include complete outputs from MELTS thermodynamic simulations and Rayleigh fractionation modeling, which support the discussion of vanadium isotope fractionation mechanisms presented in the main text.
