Metamorphic Rocks

A fine-grained, foliated, homogeneous metamorphic rock made from an original shale-type sedimentary rock of clay or volcanic ash by low-grade regional metamorphism. It is the finest-grained foliated metamorphic rock, and its foliation lies in planes perpendicular to the direction of metamorphic compression rather than along the original bedding, which is why it splits into the flat sheets that roof buildings.

  • Article text
    The foliation in slate, called "slaty cleavage", is caused by strong compression in which fine-grained clay forms flakes to regrow in planes perpendicular to the compression.

    The most important accessory minerals are iron oxides (such as hematite and magnetite), iron sulfides (such as pyrite), and carbonate minerals.
