Compositions of immiscible Si-droplets, Fe-Ti-spots, and Fe-Si-intergrowth and their associated volcanics in the Xiaoliangling Group of the ca. 1785 Ma Xiong’er igneous province

This dataset includes whole-rock compositions of rocks and in situ compositions of immscible glass in the volcanics of the Xiaoliangling Group of the 1785 Ma Xiong'er volcanic province. The whole-rock compositions are measured by XRF and ICP MS methods. The in situ compositions of glass are analyzed by both EPMA LA ICP MS methods.
