Pyritization in Stone-Building Materials Modeling of Geochemical Interaction

Stone-building materials, despite their natural origin, must be tested for the concentration of trace elements necessary to assess impact on environment and humans. In addition basic research determining mineral composition structural textural features, it is important analyze geochemical interactions between material matrix that have a negative surrounding our health. presented study, mineralogical studies were carried out Carpathian sandstones. It was shown studied sandstones are represented by lithic wackes sublithic arenites. Rocks subject secondary process sulfide mineralization observed among Pyrite in geomaterials took various forms. A detailed analysis which iron sulfides acted as binder. The aimed at identifying possible variations elements, with particular emphasis contact silica mineralized phases. assessment interaction successively enlarged measurement using Mamdani–Assilian fuzzy inference model.
