| Abstract: | Drill cores from a Bavarian hazardous waste landfill were investigated for their mineralogical composition. Because of the
formation of many new minerals, geochemical equilibrium calculations were performed to find the most stable state of the waste
body. A comparison of mineralogical observations and geochemical modelling was undertaken. The remaining solubilities of the
newly formed secondary mineral assemblages were calculated. Newly formed minerals were shown using electron microscopy.
