Jiangxi province has many natural drinking mineral water resources,with a total of 175 drinking natural mineral water points in the province.This article analyzes the distribution,hydrochemical characteristics,formation conditions,topography,lithology,geological structure,geochemical conditions,groundwater hydrodynamic and the genesis of natural mineral water in various prefecture level cities in Jiangxi province.It summarizes the distribution characteristics,occurrence and genesis laws of drinking natural mineral water in Jiangxi province.Research has shown that there are significant differences in the formation conditions of different types of mineral water in Jiangxi province.Metasilicate single and composite mineral water mainly exist in medium acidic intrusive rocks,shallow metamorphic rocks,and red clastic rocks;The types of mineral water containing strontium,lithium and lithium-strontium are mainly found in carbonate rocks and red clastic rocks;The types of mineral water containing carbon dioxide are all located near deep faults,with deep faults serving as carbon dioxide reservoirs and secondary faults functioning as gas conduits.The leaching process is the main process for the formation of mineral water in Jiangxi province.The factors affecting leaching intensity suggest that areas with abundant rainfall,well-developed structures,and undulating terrain have better groundwater recharge,runoff,and alternation,which can maintain strong leaching intensity.This confirms that mineral water in Jiangxi province is mostly distributed along fault structural zones,mostly in hilly and mountainous areas,with very few occurrence in the plain areas.
