| Distribution and Evolutional Mechanism of Shallow High_Fluoride Groundwater in Taiyuan Basin |
| Distribution characteristics of the shallow high-fluoride groundwater in Taiyuan basin are discussed in this paper. It is indicated that the shallow high-fluoride groundwater is mainly distributed in the southern area of Taiyuan basin, and F-concentration is getting higher from west to east. A statistical analysis of the groundwater hydrochemical compositions and hydrochemical model reveals that the high-fluoride water is mainly high-mineral water and has characteristics of the transitional groundwater type, i.e., it is dominantly alkaline groundwater of NaCa or NaMg type. F-contents are consistent with the proportions of the main ions in the groundwater. During the evolution of the high-fluoride groundwater, the hydrochemical actions of dissolution and evaporation control the variation of F-contents. |
