Phyllite
last edited:  8/3/02    number of photos: 17
Phyllite is metamorphosed shale.  It is a foliated                               
metamorphic rock, often with a silky sheen due to
the presence of tiny mica crystals.  The cleavage
surface of phyllite is not flat like slate, but is
commonly rippled.
