摘要：

A case study of three springs in Switzerland is used to demonstrate the value of geochemical time-series data as a powerful tool to study the dynamics of groundwater systems. Values of repeatedly measured parameters revealed intermixings of two water types: (a) a 29°C water, circulating to a depth of ∼1100 m and containing approximately 700 mg/l Ca, 2000 mg/l SO4, 700 mg/l HCO3, 20 mg/l of Na and Cl, 6 mg/l Fe, at least 47 mg/l SiO2, and with an isotopic composition of δD = - 73.0‰ and δ18 O = -10.9‰, and (b) a 12°C or colder water, shallow, and of a post-1953 age, containing 420 mg/l TDI or less, very low in Na and Cl (4 mg/l or less), isotopic values of δD = -71.0‰ and δ18 O = -10.5‰ and tritium as in recent (post-bomb) precipitation. © 1990.
