This type of metamorphic rock has been buried very deep and squeezed very hard. In this hand specimen from Ward Creek, California, glaucophane is the major blue mineral species. For instance, a blueschist-facies ultramafic rock consists mainly of serpentine antigoriteolivine and magnetite. Schist forms at a higher temperature and has larger grains than phyllite.

  • Muscovite schist: The dominant visible mineral in this schist is muscovite. Its platy grains are aligned in a common orientation, and that allows the rock to be split.

    Slate forms when shale, which consists of clay minerals, is put under pressure with temperatures of a few hundred degrees or so.

    You can see many of these grains as inclusions within the garnet. Chlorite, epidote, actinolite, and serpentine the green minerals that give this facies its namebut whether they appear in any given greenschist-facies rock depends on what the rock originally was.

    Metamorphic Rock Types Pictures and Descriptions

    Schists are commonly described in terms of their predominant minerals. In geotechnical engineering a schistosity plane often forms a discontinuity that may have a large influence on the mechanical behavior strength, deformation, etc.

    The schists are classified principally according to the minerals they consist of and on their chemical composition. It is quite durable in dry climates, as in the Mediterranean countries where ancient marble structures survive.

    These were formed through metamorphism of the clay minerals present in the protolith.

    This metamorphic rock forms in two different ways.

    Such rocks as limestonesdolomitesquartzites and aluminous shales have very definite chemical characteristics which distinguish them even when completely recrystallized.

    Garnet mica schist: This rock is composed of fine-grained muscovite mica with numerous visible grains of red garnet. The white mineral is aragonitean alternative crystal form of calcium carbonate its other form is calcite. Unlike slate, phyllite has a definite sheen.

    Yet even with this extreme degree of metamorphism, the minerals are arranged in layers and the rock is clearly classified as metamorphic.

    1. Yozshuzshura:

      Its platy grains are aligned in a common orientation, and that allows the rock to be split easily in the direction of the grain orientation.

    2. Voodoogis:

      These veins contain mainly biotite. The platy minerals can be graphitetalcor hornblende from carbonaceous, basaltic, or other sources.

    3. Faemuro:

      This is a microscopic thin section. In geotechnical engineering a schistosity plane often forms a discontinuity that may have a large influence on the mechanical behavior strength, deformation, etc.

    4. Meziran:

      It is formed by dynamic metamorphism at high temperatures and high pressures that aligns the grains of mica, hornblende, and other flat or elongated minerals into thin layers, or foliation.

    5. Meztikazahn:
