The Mica Schist Family of RocksMica-schist is a rock composed essentially of quartz and mica, usually either muscovite or biotite The mica is the prominent mineral, occurring in irregular leaves and in foliated mass The mica plates all lie with their cleavage planes parallel to each other and give to the rock a striking laminated or "schistose" structure...
