摘要
本文揭示了第三系沉积体系地下水化学的基本特征及其在正向、斜向上的水化学分带性，从古代和现代水文地质条件分析，论证了现代水化学场是遵循浓缩盐化、正向变质和稀释淡化、反向变质两种格局形成演化的，指出第三系地下水现代化学业已演化成熟，并概括了形成演化模式。
The basic characteristics and positive, insequent zonation of groundwater chemistry of Tertiary sedimentary system are revealed in the paper. Based on ancient and modern hydrogeology, what the hydrochemical field is forming and evoluting in accordance with two patterns, namely, concentration_salinization, positive metamorphism and dilution-desalinization, nagative metamorphism is analyzed and proved. It is also pointed out that the modern chemistry of Tertiary groundwater has already evoluted to maturity, in conclusion, the formation and evolution pattern is summarized.
