Two models of reversible and irreversible water – mineral interaction are developed to simulate geochemical evolution of old groundwater in the Cenomanian and Turonian sandstone aquifers in the Bohemian Cretaceous Basin in Central Europe. The kinetic constants of dissolution and equilibrium constants of reversible reactions are results of laboratory experiments published in literature. Reactive surface areas of minerals are calculated. The model simulates the evolution of the chemical composition of groundwater whose age was derived from isotopic data. The results are compared to the chemical composition of groundwater along the trajectory of the prevailing flow. The model represents the interaction between groundwater and sandstones containing quartz, amorphous silica, a mixture ... view moreĀ»
