根据研究区的水文地质条件,结合热力学原理和化学原理,确定典型剖面和矿物相,采用反向地球化学模拟软件NETPATH2.0,对吉林省西部地区水-岩相互作用进行模拟,从而对潜水水化学演化进行分析。典型剖面上的模拟结果表明:第四系孔隙潜水在径流排泄过程中,主要发生了矿物的溶解和沉淀,以及Na+、Ca2+之间的离子交换,使得沿剖面上的水化学类型发生了相应的改变。
According to the hydrogeological conditions in the study area, the typical sections and mineral facies were determined by combining thermodynamic principles and chemical principles. The reverse geochemical simulation software NETPATH2.0 was used to simulate the water-rock interaction in the western Jilin Province, Chemical evolution for analysis. The simulation results of typical sections show that during the process of runoff drainage, the dissolution and sedimentation of minerals and the ion exchange between Na + and Ca2 + occurred mainly during the runoff drainage in the Quaternary pore scuba diversion, so that corresponding change.
