摘　　要： 盘山花岗岩主体是石英二长岩，对其不同风化程度的岩石进行浸泡和淋滤实验，研究水岩作用受作用时间，水动力条件及岩石风化程度等因素对矿泉水化学成分的影响，得出：①水岩作用时间愈长、水流速度愈大则溶质溶出量也愈大，但随着时间增长，溶质溶出速率明显减小；②在时间、流速条件相同时，不同风化程度的岩五溶出量不同，其中半风化岩石溶质溶出量最高；③溶出物质主要有钙、镁、钾、钠、可溶性二氧化硅、锶等。据实验条件下可溶性二氧化硅、锶溶出速率，估算出盘山地区偏硅酸型矿泉水的形成时间约为２６年，锶型矿泉水形成时间约为８年。 Panshan Granite body is dominated by quartz monzonite in which mineral water is discovered and developed. This paper presents the test results on mechaism of the mineral water. The monozite samples with various weathering were dippd in water and leached under different water dynamic condition. The results show :① the longer water reacts with rock and the biger the water flow is the more the solvents are extracted from rock but extracted rate is reduced as time extended;②under same period and water flow the extracted material amount are different i. e. maximum is the semi-weathered Samples;③Ca, Mg ,K ,Na ,soluble SiO_2 and Sr are the main materials from the rock. Based on rate of SiO_2 and Sr in the test it is about 26 years to form slight Si-acidic mineral water and 8 years for Sr mineral water.
