| Exploration of Mineral Water Outcropping Pattern in the Mountainous Area of South Jiangxi |
| South Jiangxi is a typical mountainous area, and it is also a severe water shortage area. Generally, high-quality mineral water flows out of the ground on both sides of mountain valleys. Ningdu County is located in the northern part of South Jiangxi and has the typical geomorphological features and structural features of South Jiangxi. Taking Ningdu County as an example, the authors investigated the distribution and exposure patterns of mineral water. Through regional geological survey, hydrogeological conditions analysis and water quality analysis, it is found that the type of mineral water is mainly silicic acid mineral water, with content of 30.72~48.56 mg/L, the water chemistry type is HCO3-Ca·Na type water, the water temperature is generally lower than 25 °C, and the total dissolved solids are less than 153.53 mg/L, thus belonging to low mineralization cold mineral springs. The fault structure provides hydrodynamic conditions for the formation of mineral water, and also provides a good space for the transfer and storage of mineral water. The topography and landform are dominated by eroded structural hilly hills. Large runoff and deep cutting conditions promote the enrichment of metasilicic acid in groundwater. The high content of SiO2 in granite provides a material basis for mineral water, and has a high degree of weathering, fissure development, and water-rock interaction. |
