Based on chemical-thermodynamical balances the species distributions and mineral stabilities of the chemical compositions of the pressed pore solutions taken from a Baltic Sea mudsediment are evualuated by means of the computer program WATEQF (PLUMMER et al., 1976). According to these evaluations calcite and aragonite are to be found in supersaturation throughout the whole profile. The SiO2 concentration of the pore solutions is mainly controlled by the dissolutions of amorphous silica present in minimal undersaturation. By means of SEM pictures idiomorph quartzcrystals as well as presumptive clay minerals transformation and reformations could be proved as stable transformation phases of the dissolved SiO2 species. The stability of the solid phases containing Al-components as of feldspars and clayminerals decreases with increasing dept and is mainly controlled by AIF3 complexes higher concentrated with increasing depth.
