摘要
为了解新疆祁漫塔格地区地下水化学特征及主要离子来源,依据地下水采样调查数据,综合利用数理统计分析、Piper三线图、Gibbs图、离子比值和水文地球化学模拟等方法进行分析探讨。结果表明:研究区地下水总体呈弱碱性;地下水化学类型主要为Na-Cl·SO_(4)型、Na·Mg-Cl·SO_(4)型和Na·Mg-Cl·SO_(4)·HCO_(3)型;蒸发浓缩作用和岩石的风化溶解是影响和控制研究区地下水化学成分的首要因素,其中,岩石的风化溶解以蒸发岩(石膏和盐岩等)和硅酸盐(钾长石、钠长石、钙长石和镁长石等)的溶解为主。
To analyze the hydrochemical characteristics and main ion sources of the groundwater in Qimantage area,Xinjiang,the mathematical statistical analysis,Piper trilinear diagram,Gibbs diagram,ion ratio and hydrogeochemical simulation were used for the analysis and discussion based on the groundwater investigation data.The results showed that the groundwater in the study area was generally weakly alkaline and the main chemical types of the groundwater were type Na-Cl·SO_(4),type Na·Mg-Cl·SO_(4) and type Na·Mg-Cl·SO_(4)·HCO_(3).Evaporation concentration and weathering and dissolution of rocks were the primary factors that affected and controlled the chemical composition of the groundwater.Among them,the weathering and dissolution of rocks was dominated by the dissolution of evaporite(gypsum,salt rock) and silicate(potassium feldspar,albite,anorthite and magnesite).
