The study of chemical weathering is of great significance to understand how the plateau uplift regulates the mechanism of climate change and the circulation of elements and materials in the sphere. The data set is the seasonal major element concentration and stable isotope data of the river water at the hydrological station of the Yellow River Basin originating from the Qinghai Tibet Plateau. There are two hydrological stations in total: 1. Longmen hydrological station in the middle reaches of the Yellow River is the high-resolution (weekly) sample data collected in 2013, and the element concentrations include K, CA, Na, Mg, SO4, HCO3, Cl, etc. The cation data of collected water samples are tested on ICP-AES of Institute of earth environment, Chinese Academy of Sciences, and the anion data are tested on ion chromatograph (ics1200) of Nanjing Institute of geography and lakes, Chinese Academy of Sciences. The uncertainty is within 5%, and HCO3 is tested by titration. The high-resolution (weekly) Li isotope data of river water was tested in MC-ICP-MS of Institute of earth environment, Chinese Academy of Sciences in 2017, and the test accuracy 2sd is better than 5 ‰; 2. Tangnaihai hydrological station on the Yellow River is the river water (month by month) data set collected from July 2012 to June 2014. The major element concentrations include K, CA, Na, Mg, SO4, HCO3, Cl, etc., and the stable isotope data include s, O and H. The data set can be used to study the modern weathering process under the background of the uplift of the Qinghai Tibet Plateau, and provides the first-hand reliable data for the study of physical erosion and chemical weathering in the basin.

The content of this data is the hydrogeological map of the Western Branch of the upper reaches of Heihe River, including stratum, river, fault, modern glacier and other information; the data is scanned and corrected by yeniu platform sheet comprehensive hydrogeological map, Qilian Mountain sheet comprehensive hydrogeological map, Qilian sheet comprehensive hydrogeological map and Sunan sheet geological map (1:200000), and the stratum is adjusted according to the field survey Together. This data can provide us with a better understanding of the lithology, structure, geomorphology, hydrogeological conditions of the Western Branch of the upper reaches of the Heihe River. It is convenient for researchers to have a clearer understanding and understanding of our work scope and research field, and facilitate retrieval and download.
