藏东南珠西沟冰川融水化学数据（2020-2021）

数据包含珠西沟冰川径流的钾、钠、钙、镁、氟离子、氯离子、硫酸根和硝酸根等指标，涵盖了大部分无机溶解组分。上述阴阳离子分别采用离子色谱和电感耦合等离子光谱仪等仪器测得，检测限低于0.01mg/L，误差低于10%；本数据可以用于反映珠西沟流域硫化物氧化、碳酸盐岩溶解和硅酸盐岩风化等化学风化过程对河水溶质的贡献，进而精准计算碳酸盐岩风化速率和硅酸盐岩风化速率，最终为评估冰川作用对岩石化学风化及其碳汇效应的影响提供科学依据。This dataset contains indicators including potassium (K⁺), sodium (Na⁺), calcium (Ca²⁺), magnesium (Mg²⁺), fluoride ion (F⁻), chloride ion (Cl⁻), sulfate (SO₄²⁻) and nitrate (NO₃⁻) in the glacial runoff of Zhuxigou Glacier, covering most of the inorganic dissolved constituents. The above-mentioned anions and cations were measured using instruments such as ion chromatography (IC) and inductively coupled plasma spectrometer (ICP), with detection limits below 0.01 mg/L and measurement errors less than 10%. This dataset can be used to reflect the contributions of chemical weathering processes including sulfide oxidation, carbonate rock dissolution and silicate rock weathering in the Zhuxigou Basin to river solutes, thereby accurately calculating the weathering rates of carbonate rocks and silicate rocks, and ultimately providing a scientific basis for evaluating the impact of glaciation on rock chemical weathering and its carbon sink effect.
