摘要
通过分析常规水化学组分显示,汉中玉矿区地下水水化学类型主要为HCO_3-Ca·Mg型和HCO_3-Ca型。前者赋存于麻窝子组白云质大理岩中,属弱碱性微硬水,后者赋存于晋宁期侵入岩体中,属弱碱性极软水,均达到偏硅酸矿泉水标准。
Analysis of conventional water chemical composition indicates that the hydrochemical types of underground water in jade mining area of Hanzhong are dominant in HCO3-Ca·Mg and HCO3-Ca. The former occurs in dolomitic marble of the Mawozi Formation, belonging to slightly alkaline water, and the later in Jinningian intrusive rocks belonging to alkalescent very soft water. The both reach the standard of partial silicate mineral water.
