This data includes main and micro geochemical data of the whole rock, 40Ar / 39Ar dating data of phlogopite, and Sr-Nd isotope data of the whole rock. The samples were collected from the edge of the Ramba dome in eastern Tibet. The argon isotope of phlogopite uses the stage heating method, and the plateau age and isochron age are calculated by ArArCALC software; The major elements in the whole rock were analyzed by X-ray fluorescence spectrometry (XRF); Trace elements in the whole rock were measured by Quadrupole Inductively coupled plasma mass spectrometer (Q-ICPMS); Sr-Nd isotopic composition was obtained by MC-ICP-MS. The data obtained show that the age of the phlogopite plateau is 13.1 ± 0.18 Ma, which is consistent with the inverse isochron age; The ultrapotassic melt comes from the partial melting of lithospheric mantle in the Indian continent, and the source depth is shallow, so it should be a spinel stable area.

File naming and required software

The data is stored in Excel format. The document name is "PhlAge", which represents the age of phlogopite; "WRMajTra", represents major and trace elements of the whole rock; "WRIso" stands for whole-rock isotope.
