Bilingual glossary of geology

Type of foliation characteristic of schists. It is characterized by the parallel arrangement of macroscopic sheet silicates minerals such as micas and chlorite, and a slight bending of the crystals giving the rock a crenulated or undulated appearance. In a sequence of increasing metamorphic conditions, schistosity follows phyllitic texture, and precedes gneissosity.
