B isotopes from alkaline volcanic rocks in Tangra YumCo rift, Southern Tibet, to study the origin of high-silica ultrapotassic magmas in collisional settings

This supporting information provides the data of bulk rock B isotopes of alkaline volcanic rocks from Tangra Yumco rift, southern Tibet. B isotopes and contents were measured by MC-ICP-MS, using solution introduction and a standard+X cone configuration. This data is used to support our study of understanding the origin of alkaline magmas in collisional tectonic settings.
