2026-08-26 Raw Dataset of Sediment Grain Size, OSL Dating and Salt Ions from DGL-B Tamarix Nebkha Profile in Qaidam Basin doi:10.57760/sciencedb.j00265.0002q en This dataset is the core raw data of the paper "Development Process and Salt Flux Variation of Tamarix Nebkha in Qaidam Basin" (DOI: 10.3724/j.yhyj.2026081), collected from the DGL-B Tamarix nebkha profile in the Qaidam Basin. It contains 4 structured worksheets: 1. Basic information of field sampling: profile metadata, sampling scheme and paper related information; 2. Conductivity and water-soluble ion data: conductivity and contents of eight ions of 24 sediment samples, with a sampling interval of 10 cm, covering a depth of 10-240 cm; 3. Raw data of grain size distribution: particle size-volume percentage distribution data of 24 sediment samples, which is the original test result of Mastersizer 2000 laser particle size analyzer; 4. OSL dating results: complete test results of 7 OSL dating samples, including K/Th/U content, dose rate, equivalent dose and final OSL age. This dataset fully supports all figures and conclusions of the paper, and can be used for studies on the sedimentary process, salt flux variation and environmental evolution of Tamarix nebkha in the Qaidam Basin.
