Indentifying materials using Mo isotopes in intraplate alkali basalts from southeastern margin of Tibetan Plateau

This study hypothesizes that there are different recycled mantle materials in the deep mantle, which can be identified using molybdenum (Mo) isotope ratios. This dataset comprises analysis data of intraplate alkali basalt samples collected from the southeastern margin of the Tibetan Plateau. These data include Mo isotope ratios, Sr, Nd, and Pb isotope ratios, as well as the major and trace element compositions of the samples. The data analysis reveals significant variations in Mo isotope ratios among the samples, indicating the presence of different types of recycled materials in the mantle source regions of these basalts. This study supports the capability of Mo isotopes to trace different recycled materials in the mantle.embargo period.
