WebDec 1, 2012 · Heavy mineral deposits are categorised as primary (magmatic, hydrothermal, metamorphic) or secondary (weathered, eroded, and transported sediments) deposits. 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). real bloody mary videos youtubeWebThe term diagenesis has been used for the many processes that are involved in post-depositional alteration of freshly deposited sediment.
