The chemical weathering dataset of the Laohugou Glacier, Qilian Mountains (2018) was developed based on the hydrochemical data in Laohugou Glacier River, Qilian Mountains collected in 2018, integrated with the results of a mixing model. The dataset includes the following data in Laohugou Glacier: (1) location of the water sampling sites; (2) The δ18O and Cl- in the samples ; (3) results of hydrograph separation using stable isotopes; (4) ion concentration in the river water; (5) ion concentrations in the sample river water after correction; (6) Na+ normalized concentrations; (7) mass contributions of endmembers to the cations of the Laohugou glacier river, (8) mass contributions of endmembers to SO42- in the Laohugou Glacier River. The dataset is archived in .shp and .xlsx formats, and consists of 7 data files with data size of 20.9 KB (Compressed into one file with 17.2 KB). The paper based on this dataset was published at Acta Geographica Sinica, Vol. 78, No. 7, 2023.
