2010年以来，对研究区内水文地质背景及不同层位水质化学测试样品数据分析研究，重点阐述了微量元素F e3＋的富集与含水介质岩性、地下水的酸碱度、地层含水性和氧化还原环境的关系，认为地下水中F e3＋富集赋存的最有利的环境是变质岩类地层；碳酸盐岩和碎屑岩中水化学类型 HCO3 Ca型水分布最广，碳酸盐岩的地下水中Fe3＋平均含量最低；变质岩中硫酸型（包括复合型）的地下水中 Fe3＋的平均含量最高，对 Fe3＋的行为呈正相关关系。地下水中F e3＋含量赋存具以副井及其外围地区为中心高浓度分带性。

Since 2010 ,hydrogeological background and chemical testing data of water quality in different layers in studying area have been analyzed .Relation between the enrichment of trace element Fe3+ and li‐thology in aqueous medium ,pH value of groundwater ,water bearing property and oxidation reduction environment has been introduced emphatically .It is regarded that the most favorable environment for Fe3+enrichment is metamorphic rocks ;HCO3 Ca type water is widely distributed in carbonate and clastic rocks ;the average content of Fe3+ is the lowest in carbonate type in groundwater ;while the average con‐tent of Fe3+in sulfate type (including complex) groundwater in metamorphic rocks is the highest .Thus ,it showes a positive correlation with Fe3+ .Fe3+ content in groundwater occurres a high concentration of zo‐nation in auxiliary shaft and its surrounding areas .
