木里矿区是青海省重要的矿产资源区，由于临近大通河支流莫日曲，因此矿区水分及重金属的迁移规律对河水水质保障及周边的生态保护具有重要意义。氢氧同位素及铅同位素常被用于指示水分及重金属的迁移过程，因此本数据在研究区内选取沿河道方向及垂直河道方向共22个点位，分别于冻结期、消融期及汛期三个阶段对样品进行材料，共采集河水样品61个，土壤样品143个。对所采样品进行氢氧同位素、常量离子、重金属元素及铅同位素的含量进行测定，所测数据为高寒矿区重金属的迁移规律分析提供基础数据支撑。

Sampling work was conducted on the soil and surface water in the Juhugeng mining area of the Muli coalfield in Qinghai Province. The grid sampling method was used, and factors such as sampling point density and river characteristics were considered to select sampling points. Soil and water samples were numbered and stored separately using a soil ring knife and sampling bottle. The chemical pretreatment and mass spectrometry determination of heavy metals and lead isotopes in soil samples were completed in the laboratory of Beijing Clearing Technology Research Institute. Inductively coupled plasma mass spectrometry (ICP-MS) was used to determine the lead isotope ratios in soil profiles and end components in the study area; Using atomic absorption spectrophotometry and atomic fluorescence spectrometry to detect heavy metal concentrations; The determination of hydrogen and oxygen isotopes, chloride ions, sulfate ions, sodium ions, potassium ions, magnesium ions and calcium ions of surface water samples was completed in the Analysis and Test Center of Sanjiangyuan State Key Laboratory of Qinghai University. The LI-2100 full-automatic vacuum condensation extraction system and liquid water isotope analyzer were used to detect hydrogen and oxygen isotopes. The determination of carbonate ions and bicarbonate ions was completed in the Analysis and Test Center of Chinese Academy of Sciences Qinghai Salt Lake Research Institute using inductively coupled plasma atomic emission spectrometry (ICP-AES).

Due to its proximity to the Moriqu tributary of the Datong River, the migration patterns of water and heavy metals in the mining area are of great significance for ensuring river water quality and protecting the surrounding ecology. Hydrogen and oxygen isotopes, as well as lead isotopes, are commonly used to indicate the migration process of water and heavy metals. Therefore, this study selected 22 points along and perpendicular to the river channel direction in the research area, and collected 61 river water samples and 143 soil samples during the freezing period, melting period, and flood season. Determine the content of hydrogen and oxygen isotopes, constant ions, heavy metal elements, and lead isotopes in the collected samples, and provide basic data support for the analysis of heavy metal migration patterns in high-altitude mining areas.
