Heat changes the original minerals in the rock to make new rock 2) regional metamorphism—this metamorphism occurs when rocks are buried over a wide area and the heat & pressure changes the rocks. This normally happens near mountains. Two Main Groups of Metamorphic Rocks: 1)foliatedthese are metamorphic rocks where the minerals in them have been rearranged into parallel bands or layers 2)nonfoliatedmetamorphic rock that does not show layering or banding read pull tab first examplesmarble (parent rock: limestone), quartzite (parent rock: sandstone) click for video Pull examples schist (parent rock: phylite) slate (parent rock: shale) gneiss (parent rock: schist or granite) sedimentary and metamorphic rocks.notebook January 18, 2017 Checkpoint: what are the two main groups of metamorphic rock?
