WebThus, coexisting glauconite minerals evolve differently from illite/smectites under diagenetic conditions, as postulated by Velde (1977, p56). Glauconite forms a multi-mineral assemblage only at its upper thermal-stability limit. The limit is 320 °C in hydrothermal experiments but is surely lower in natural rocks (Velde and Odin, 1975).
