黄河龙门与唐乃亥水文站常量元素和同位素数据集（2012-2014）

化学风化研究对于理解高原隆升如何调节气候变化机制、圈层元素物质循环等有重要意义。该数据集为发源于青藏高原的黄河流域水文站河水的季节性常量元素浓度及稳定同位素数据。共两个水文站：1、黄河中游龙门水文站，为2013年采集的高分辨率（逐周）样品数据，元素浓度包括K、Ca、Na、Mg、SO4、HCO3、Cl等。采集水样的阳离子数据均在中国科学院地球环境研究所的ICP-AES上测试，阴离子数据在中国科学院南京地理与湖泊研究所的离子色谱仪（ICS1200）上测试, 不确定度均为5%以内，HCO3为滴定法测试。河水高分辨率（每周）Li同位素数据，于2017年在中国科学院地球环境研究所MC-ICP-MS测试，测试精度2SD好于5‰；2、黄河唐乃亥水文站，为2012年7月至2014年6月采集的河水（逐月）数据集，常量元素浓度包括K、Ca、Na、Mg、SO4、HCO3、Cl等，稳定同位素数据包括S、O、H。该数据集可以用于研究青藏高原隆升背景下现代风化过程，为研究流域物理侵蚀、化学风化提供了第一手可靠资料。

Research on chemical weathering holds great significance for understanding how plateau uplift regulates climate change mechanisms, elemental cycles across Earth's spheres, and other relevant scientific issues. This dataset contains seasonal major element concentrations and stable isotope data of river water from hydrological stations in the Yellow River Basin, which originates from the Qinghai-Tibet Plateau.
1. Longmen Hydrological Station in the middle reaches of the Yellow River: High-resolution (weekly) sample data collected in 2013, with major element concentrations including K, Ca, Na, Mg, SO4, HCO3, Cl, etc. Cation data of the collected water samples were measured using ICP-AES at the Institute of Earth Environment, Chinese Academy of Sciences (IEECAS), while anion data were determined via ion chromatography (ICS1200) at the Nanjing Institute of Geography and Limnology, Chinese Academy of Sciences (NIGLAS). The measurement uncertainties for all analytes are within 5%, except for HCO3 which was tested by titration. High-resolution (weekly) lithium isotope data of the river water were measured using MC-ICP-MS at IEECAS in 2017, with the measurement precision (2SD) better than 5‰.
2. Tangnaihai Hydrological Station of the Yellow River: Monthly river water dataset collected from July 2012 to June 2014, with major element concentrations including K, Ca, Na, Mg, SO4, HCO3, Cl, etc., and stable isotope data covering S, O, H.
This dataset can be used to study modern weathering processes under the background of Qinghai-Tibet Plateau uplift, providing first-hand and reliable data for research on watershed physical erosion and chemical weathering.
