云南昭通喀斯特区天然水水化学性质及地质成因
Hydro-geochemistry and Geological Genesis of Natural Water in Karst Region in Zhaotong City, Yunnan Province
摘要
Abstract
Nine river water samples and 27 fissure water samples were collected to study the ion chemistry and geo -logical genesis of natural water in Karst Region in Zhaotong City , Yunnan Province by means of statistical approa -ches such as Piper trilinear chart, Ion ratio and saturation index method .Results showed that the predominant anion and cation was HCO 3-(relative concentration: 67.3% and 70.0%) and Ca 2+(relative concentration: 60.0% and 72.1%), respectively.Total hardness (TH) in 81.7% of natural water from the fluorosis area in Zhaotong was be -tween 75 and 300 mg/L.The F-concentration (mean value 0.1 mg/L) of natural water from the fluorosis area in Zhaotong was well below the standards for drinking water quality (1.0 mg/L).The hydro-chemistry type of fissure water, of which aquifer rock was carbonatite , was Ca-HCO3 and Ca・ Mg-HCO3 .It is concluded that aquifer litholo-gy controlled the hydro-chemistry of fissure water.High quality water could be found in aquifer rock which is car -bonatite and unitary lithology in the fluorosis area of Zhaotong City .关键词
