    Metamorphic rock

    08/09/2006 · Metamorphic rock is the result of the transformation of a preexisting rock type, the protolith, in a process called metamorphism, which means "change in form" (from the Greek words meta, "change", and morphe, "form").The protolith is subjected to extreme heat (>150 degrees Celsius) and pressure causing profound physical and/or chemical change.

    Foliated Metamorphic Rocks | Mineralogy4Kids

    Foliated metamorphic rocks are formed within the Earth's interior under extremely high pressures that are unequal, occurring when the pressure is greater in one direction than in the others (directed pressure). This causes the minerals in the original rock to reorient themselves with the long and flat minerals aligning perpendicular to the greatest pressure direction.

    The structures of the metamorphic rocks are: (i) Slaty structure, (ii) Schistose structure, (iii) Gneissose structure, and. (iv) Granulose structure. (i) Slaty structure: The slaty structure is also called slaty cleavage. The rock possessing slaty cleavage has a unique property of splitting into thin sheets. The slaty cleavage may form at any ...

    Dickson Fjord in Greenland: This huge cliff (over 2,000 metres high!) is made of a metamorphic rock called gneiss. This was once a series of both igneous and sedimentary rocks, which were deeply buried, folded by huge forces, and completely recrystallised at high temperature and pressure to form this beautifully banded and folded rock.
