| The Mount Emei basalts are widely distributed in the Kunming area,where has been formed in basalt area of mineral water,one of the most representative:Biji mineral water,Songmao mineral water,Aziying mineral water,the three mineral water rich reserves,good water quality,high metasilicate.Good taste.Because of its unique advantages,the three water sources formed the famous mineral water brands in Yunnan,Lin Shan,Yunnan Shanquan and Yunnan zhenming,which produced great economic and social value.Therefore,the study of the formation mechanism of mineral water is of great theoretical and temporal significance to the development,utilization and protection of mineral water.Based on the data collection and field investigation,analysis of the hydrogeological conditions of various mineral water,combined with the characteristics of Permian basalts and Mount Emei groundwater recharge source and mechanism,explains the formation conditions of each water source;through the detection of data samples,analysis of water chemical characteristics of mineral research area based on Sufer software to study the spatial distribution characteristics of mineral water and water chemistry field,focusing on the forest mountain mineral water chemistry wells time evolution characteristics,and analyzes the water chemical field of water dynamic field of significance;hydrogeochemical simulation by using PHREEQC software,based on the analysis of the mineral saturation index,water diagenesis and cation exchange effect of mineral water.The mixing action happened in Lin Shan mineral water well.The mixed module of PHREEQC software was used for simulation.According to hydrochemical characteristics and mineral saturation index,the mixing effect and proportion of mineral water in Lin Shan were analyzed.Through the study,it is concluded that the source of mineral water is atmospheric precipitation,lithology,geological structure,topography and geomorphology have some influence on the supply of mineral water.The formation conditions are mainly controlled by special geological structure,geochemical environment,hydrogeological conditions and topography and geomorphology.The common control followed by precipitation,lush vegetation,abundant temperature,drilling depth and pollution of the environment and other factors.In the study area the spatial differences in the concentration of silicic acid,is mainly due to the development characteristics of special geochemical conditions and fracture types of the study area;the internal chemical complex,mineral water ion content showed a trend in the space evolution characteristics of forest mountain mineral water well water chemistry is mainly controlled by the mixing time the effect of water rock interaction;mineral water mainly for the dissolution of albite,anorthite and diopside,cation exchange performance of Ca2+in water displacement in surrounding rock Na+.The mixing effect of Lin Shan mineral water well is mainly shown in 2016.In 2016,Lin Shan mineral water sample was mixed with the water sample of the provincial Party School in 2001. |
