The illitization of dickite: chemical and structural evolution of illite from diagenetic to metamorphic conditions

Popis výsledku v původním jazyce

The illitization process of dickite was evidenced at diagenetic to low-grade metamorphic conditions in Triassic sedimentary rocks from the Betic-Rif Cordillera, whereas the transformation of kaolin-group minerals into illite was commonly described in deeply burried sandstone sequences. Dickite is well-ordered diagenetic phase that occurs filling the secondary porosity in sandstones and conglomerates. In diagenetic conditions, the alteration of dickite to illite produces thin 1M mica crystals with incomplete interlayer occupancy (illite), wide chemical variability, and low Na contents. Under low anchizonal conditions, the illitization process is more advanced and 2M1 K-illite coexists with minor dickite, sudoite, and 1M intermediate Na-K-illite. At higher anchizonal conditions only relics of dickite persist, whereas pyrophyllite coexists with 2M1 illite/muscovite with K-rich composition, indicating an approach to equilibrium.
