The olivine geochemical, oxygen isotopic and whole-rock major element, PGE, Os isotopic compositions of kalsilite-bearing the West Qinling olivine nephelinites.

The dataset provides in-situ olivine geochemistry, oxygen isotopes and whole-rock major element contents, PGE concentrations, Os isotopes of nephelinites in the West Qinling Orogen. The West Qinling orogenic belt is from Central China. This study focuses on the Cenozoic alkaline volcanic rocks from West Qinling, Central China, to characterize the mantle source and potential metasomatizing agent(s).
