Data set of Precambrian continental crust basement of Qilian block

Data set of Precambrian continental crust basement of Qilian block


This data includes zircon U-Pb dating of metamorphic rocks and basalts in the Precambrian continental crust remnant in the northwest of the North Qilian orogenic belt measured from 2019 to 2021, major and trace and Sr nd Hf isotopic geochemical test results of the whole rock, and major and trace geochemical test results of minerals. The main instruments used are Aglient 7500a ICP-MS, X-ray fluorescence (XRF), inductively coupled plasma mass spectrometry (ICP-MS), thermo Finnigan Triton thermal ionization mass spectrometer (TIMS), Neptune MC ICPMS and electron microprobe (EMPA). The data quality is high and within the error range. According to the data, the Precambrian continental crust fragments can be divided into three stages: Paleoproterozoic (1.7 GA), early Mesoproterozoic (1.6 GA) and middle Mesoproterozoic (1.5-1.2 GA), which were formed in the continental margin arc, intracontinental rift and initial ocean basin environment respectively. It is revealed that the Qilian block is located in the southwest of the core of the ancient lombia supercontinent.
