Metamorphic Rock Hill Science 6

The Rock Cycle

Metamorphic Rock Comes from the Greek: – “meta” – to change – “morphic” - form

Metamorphic Rocks Igneous, sedimentary, and even metamorphic rocks may be transformed by heat, pressure, and/or chemical reactions into metamorphic rocks. Phyllite- foliated metamorphic Black Limestone- sedimentary

Metamorphic Rocks Metamorphic rocks may change into other kinds of metamorphic rocks. Metamorphic rocks may be remelted and become igneous rocks.

Metamorphic Rocks

Foliated – from Latin “folia” meaning leaves as in pages of a book. – Bands or stripes are visible on the rocks Nonfoliated – No bands or stripes appear on the rock gneiss quartzite

Metamorphic Rock Foliated Rock – minerals are arranged in stripes, bands, or wavy lines. The mineral crystals are usually flat and line up with each other. gneiss slate

Metamorphic Rock Nonfoliated Metamorphic Rock- – Made of only a few minerals which are not arranged in bands or stripes. quartzitehornfels

Metamorphic Rock Foliated or Nonfoliated? granitegneiss shaleslate

Metamorphic Rock Foliated or Nonfoliated? limestonemarble sandstone quartzite
