Geochemistry of Sillimanite–Magnetite–Kaolinite

Kaolinite in the metasomatites is a dominant mineral (in contrast to what is typical of the quartzites). The mineral occurs as a number of morphological varieties. The most common one is granular aggregates of equant or elongate shape and of gray to almost black color (Figs. 3b, 3d). The kaolinite often replaces sillimanite: the rock contains lath-shaped subparallel platelets that make up accumulations.
