  2. Gneiss - Wikipedia

    en.wikipedia.org/wiki/Gneiss

    Metamorphic rock showing stronger schistosity is classified as schist, while metamorphic rock devoid of schistosity is called a granofels. [2] [3] Gneisses that are metamorphosed igneous rocks or their equivalent are termed granite gneisses, diorite gneisses, and so forth.

  3. Metamorphic rock - Wikipedia

    en.wikipedia.org/wiki/Metamorphic_rock

    Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock ( protolith ) is subjected to temperatures greater than 150 to 200 °C (300 to 400 °F) and, often, elevated pressure of 100 megapascals (1,000 bar ) or more, causing profound physical or chemical changes.

    Lapis lazuli – Metamorphic rock containing lazurite, prized for its intense blue color - A rock composed of lazurite and other minerals; Larvikite – Variety of monzonite, an igneous rock; Litchfieldite – A metamorphosed nepheline syenite occurrence near Litchfield, Maine

    The greyish rock on top is the igneous intrusion, consisting of porphyritic granodiorite from the Henry Mountains laccolith, and the pinkish rock on the bottom is the sedimentary country rock, a siltstone. In between, the metamorphosed siltstone is visible as both the dark layer (~5 cm thick) and the pale layer below it.

  6. Sandstone - Wikipedia

    en.wikipedia.org/wiki/Sandstone

    Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains, cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. [1] Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's ...

  7. Hornfels - Wikipedia

    en.wikipedia.org/wiki/Hornfels

    A sample of banded hornfels, formed by contact metamorphism of sandstones and shales by a granite intrusion. Hornfels is the group name for a set of contact metamorphic rocks that have been baked and hardened by the heat of intrusive igneous masses and have been rendered massive, hard, splintery, and in some cases exceedingly tough and durable. [1]

  8. Psammite - Wikipedia

    en.wikipedia.org/wiki/Psammite

    Psammite (Greek: psammitēs "(made) from sand", from psammos "sand") [1] is a general term for sandstone.It is equivalent to the Latin-derived term arenite [2] [3] and is commonly used in various publications to describe a metamorphosed sedimentary rock with a dominantly sandstone protolith. [4]

  9. Arenite - Wikipedia

    en.wikipedia.org/wiki/Arenite

    Arenite (from the Latin arena, "sand") [1] is a sedimentary clastic rock with sand grain size between 0.0625 mm (0.00245 in) and 2 mm (0.08 in) and containing less than 15% matrix. [2] The related adjective is arenaceous. The equivalent Greek-derived term is psammite, though this is more commonly used for metamorphosed sediments.
