Distribution and characterization analyses of strontium-bearing mineral spring water in the Chengde region

Chengde area is the water conservation function area and ecological environment supporting area of the Beijing-Tianjin-Hebei Region. In order to develop and protect the mineral spring water resources in the Chengde area, explore the origin of strontium-bearing mineral spring water and locate the potential areas of mineral spring water, we analyzed and collated a large number of strontium-bearing sample testing and analysis data based on the investigation and exploration of strontium-bearing mineral spring water, ecological hydrogeological survey, groundwater, spring and surface water sample collection, and strontium-bearing mineral spring water detection and analyses were carried out. The methods of correlation analysis, comparative analysis and factor analysis are used to quantify the strontium content in the main lithology of the study area. By means of the spatial analysis of GIS data, the distribution of strontium-bearing mineral spring water in this area is mapped by overlapping and analyzing the dada in space, and the potential tectonic zones of strontium-rich mineral spring water are located. The distribution characteristics and causes of strontium-bearing mineral spring water in the region are analyzed and examined, which may provide accurate targets for guiding further investigation in the study area to explore the potential areas of strontium-rich mineral spring water in the tectonic belts and strata.
