Tertiary Groundwater Chemical Field and Pattern of Its Formation and Evolution in Huanghua Oil Gas-Bearing Rift Basin
黄骅含油气裂谷盆地第三系地下水化学场及其形成演化模式

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.
