This data is zircon U-Pb age data of Yanshanian intermediate acid rocks in the northern margin of North China and its adjacent areas. Zircon U-Pb dating was completed using cameca ims-1280hr in the ion probe Laboratory of Institute of Geology and Geophysics, Chinese Academy of Sciences. The U-Th-Pb isotope ratio was obtained by the calibration of standard zircon Pl e sovice. Simultaneous interpreting of the standard deviations obtained from the long-term monitoring of standard samples and the accuracy of the single point test were used to obtain the sample single point error, taking the standard sample Qinghu as the accuracy of the unknown sample monitoring data. The measured 204Pb value is used for ordinary Pb correction. The isotopic ratio and age error are all 1 σ。 Harmonic age and mean age were calculated using isoplot software. Through the obtained data, we can find out the temporal and spatial distribution of magmatism in the study area, establish the chronological framework of the northern margin of North China and its adjacent areas, and provide chronological basis for further study of geodynamic mechanism in this area.

The data are the whole rock mg isotopic geochemical data of Yanshanian intermediate acid rocks in the northern margin of North China and its adjacent areas. The whole rock mg isotope data were obtained by MC-ICP-MS analysis. During the whole test period, the indoor standard samples were analyzed and tested, and the results were consistent with the previous reported data of the same standard sample within the error range, which showed that the Mg chemical composition process of the sample did not produce fractionation caused by improper manual operation. In addition, the test results of international standard samples mag-1 (mudstone standard sample), bhvo (basalt standard sample), andesite standard sample and rhyolite standard sample are also consistent with the previously published data, which further ensures that the artificially introduced fractionation is generated in the whole set of chemical treatment process including dissolved samples. Finally, the repeated analysis of the same sample has obtained consistent results, which proves the good reproducibility of Mg isotope test. Through the obtained data, the variation law of isotopic composition in the study area can be found out, the properties of rock source area, melting conditions and magmatic evolution process can be analyzed in detail, and the dynamic process of tectonic magmatic process can be traced.

The data set mainly includes typical rare earth deposits in China, such as Maoniuping and Lizhuang rare earth deposits in Mianning, Western Sichuan, and Gansha OBO rare earth deposits in Gansu Province. These rare earth deposits are genetically related to carbonate alkaline rock complex. In situ U-Pb dating, whole rock major and trace elements, Sr nd Pb radioisotopes, C-O-B-Ca stable isotopes and mineral in situ major and trace elements contents of rocks or ores in these complexes were analyzed. The major elements were measured by X-ray fluorescence spectrometer (XRF), the trace elements were measured by inductively coupled plasma mass spectrometry (ICP-MS), and the isotopes were mainly measured by mc-icp-ms. The main conclusions are as follows: (1) it is revealed that the magma source area of alkaline carbonate type REE deposit experienced the addition of strong subduction material, and its formation depth may be deeper than previously thought（2) It is revealed that the aegirization may be related to carbonatite and alkaline magmatism, and there may be differences in the aegirization between the two types of magma（3) The later reformation of the rare earth deposits with younger age may be relatively weak, while the rare earth deposits with older age are easy to be influenced by the later geological process and difficult to distinguish.

Modern solid sediments are widely distributed in the Yarlung Zangbo River Basin, including different types of river sediments in different sedimentary environments. In this scientific research, we have carried out a detailed field geological investigation on the sand in the main stream of the Yarlung Zangbo River and about 100 tributaries in China. More than 150 solid sediment sites were investigated during this scientific research. In each site, not only field information, sedimentary description and photos were collected, but also river sand sample was collected systematically. Studying the composition and distribution characteristics of solid sediments in Yajiang river basin is of great scientific and social value for revealing the source-to-sink process and evolution of river system, soil and water conservation, early warning and prevention of natural disasters, and major infrastructure construction.
