This data is based on the basic hydrogeological data of the study area, and water samples were tested for hydrochemical ions and hydrogen oxygen isotopes. Mathematical statistics, Shukalev classification, Piper trilinear diagram, and Gibbs diagram were used to analyze the hydrochemical characteristics, types, main ion composition characteristics, sources, and influencing factors of different water bodies. Furthermore, the transformation methods of precipitation, surface water, groundwater, and mine water in different periods of the study area were analyzed, clarifying the process and influencing factors of precipitation surface water groundwater transformation in the basin. Environmental isotopes and multivariate mixing models were used to analyze the transformation relationship and intensity of different water bodies in the basin.
Negotiate with mining staff to obtain and conduct self sampling and testing.
The concentration of anions and cations was tested using an ion chromatograph (Dionex Aquion); The bicarbonate ion test was conducted using the hydrochloric acid methyl orange titration method.
Hydrogen and oxygen isotopes were tested using the LGR (Los Gatos Research) liquid water isotope analyzer (model IWA-45EP). The testing accuracy of the instrument, δ 180, is better than ± 0.1 ‰, and δ D is better than ± 0.5 ‰, both of which meet the measurement accuracy requirements.
The data quality is good.
