摘　　要：文章分析了蓟县官庄盆地的水文地质特征以及地下水埋藏条件、边界条件、补径排条件、动态特征、水化学与环境同位素特征。分析了矿泉水特征组分偏硅酸的形成机理,表明花岗岩中大量的石英、铝硅酸盐矿物在深循环条件下的水解作用是偏硅酸的主要成因。Hydrogeologic characteristics, occurrence, boundary conditions, recharge, flow and drainage conditions, dynamic and hydrochemical characteristics, and environmental isotopic characteristics of the groundwater in the Guanzhuang basin in Jixian, Tianjin, are analyzed in this paper. The formation mechanism of metasilicic acid is examed, which is one of the characteristic contents of the mineral water . The metasilicic acid is from the hydrolytic decomposition in depth of quartz and aluminum-silicate minerals , which is rich in the granite in the area.
