The data are isotopic dating data, zircon HF-O isotopic data, rock whole rock major and trace data, rock whole rock isotopic geochemical data. The samples were collected from the late Devonian magmatic rocks of Chaka, riwan, Qiangtang, Qinghai Tibet Plateau. Radioisotope geochronology data were obtained by analyzing zircon U-Pb isotopes with secondary ion microprobe. HF and O isotopes of minerals were obtained by laser ablation inductively coupled plasma mass spectrometry and secondary ion probe analysis, respectively. The major, trace and isotopic geochemical data of whole rock were obtained by X-ray fluorescence spectrometry and inductively coupled plasma mass spectrometry, and the whole rock isotopic geochemical data were obtained by inductively coupled plasma mass spectrometry. The data obtained can define the early evolution history of the Qiangtang paleoTethys ocean.

File naming and required software

All data are stored in Excel file. The file name "UPB. XLS" represents radioisotope data. The file name "zrhfo" represents zircon HF-O isotope data. The name of the file "whmajtra" represents the whole rock master and trace data. The file name "wriso" represents the whole rock isotopic geochemical data.
