متن کاملMontmorillonite/illite Stability Diagrams
Chemical activity diagraoas , prepared to illustrate the properties expected if mixed-layer montmorillonite/illite is regarded as a solid solution, are compared to those derived from a treatment of these materials as a mixture of two phases. If the system is a solid solution, the coexisting aqueous solution should range from higher dissolved silica contents in the presence of kaolinite and a mo...
متن کاملA Proposed Phase Diagram for Illite, Expanding Chlorite, Corrensite and Illite-montmorillonite Mixed Layered Minerals
-New and published experimental data on hydrothermally treated (2-kbar water pressure, 300-400~ natural clay minerals is used to construct phase diagrams in composition and pressure-temperature space which define the phase relations of mixed layering solid solution in dioctahedral (illitemontmorillonite) and trioctahedral expanding chlorite and corrensite-like minerals. Three major relations ar...
