Mica is not a type of foliated rock but is in fact the name for a subdivision of a group of minerals known as Phyllosilicates.
They form as parallel sheets of silicate tetrahedra resulting in thin sheet like crystals. Foliations are planer alignments of crystals within metamorphic and igneous rocks and foliated rocks may contain micaceous minerals.
See the related link for a picture of a Quartz-Mica Schist seen in thin section and viewed through a petrographic microscope with the polarising filters crossed.
In the example picture the white, grey and black amorphous blobs are quartz crystals and the long, thin, brightly coloured (predominantly blue and yellow) crystals are muscovite mica.
