Definitions

1. Metamorphic rock is the result of the transformation of an existing rock type, the protolith, in a process called metamorphism, which means "change in form". (Web site)
2. A metamorphic rock is ANY type of rock that gets changed by heating and squeezing.
3. Metamorphic rock is sedimentary or igneous rock that has been subjected to intense heat and high pressure, usually inside the mantle. (Web site)
4. Metamorphic rock is rock that has changed from one type of rock into another. (Web site)
5. Metamorphic Rock is formed by great heat, or pressure, or both. (Web site)

Phyllite

1. Phyllite is a rather soft metamorphic rock of such fineness of grain that the individual mineral particles can only be seen under a microscope.
2. Schist is a medium-grade metamorphic rock, so it has experienced more heat and pressure than both slate and phyllite.

Igneous Rocks

1. Igneous rocks can also be subjected to heat and pressure and be changed into metamorphic rock.

Magmatic Rock

1. Magnetite ore is produced more in magmatic rock, metamorphic rock, and beach sand.

Sedimentary Rock Becoming

1. Describe a specific example of a sedimentary rock becoming a metamorphic rock. (Web site)

Metamorphosed

1. Schist is metamorphic rock that originated from the dark igneous rock that its reaction becomes alkaline and clay sedimentary rock by metamorphosed.

Older Metamorphic Rock

1. These rocks form from the deformation of previously existing igneous, sedimentary, and even an older metamorphic rock. (Web site)

High Grade Metamorphic Rock

1. The country rock itself is generally high grade metamorphic rock.

Coarse-Grained Metamorphic Rock

1. Gneiss A coarse-grained metamorphic rock, with compositional layering and alignment of minerals, produced under conditions of regional high pressure. (Web site)

Parent Rock

1. The properties (characteristics) of a metamorphic rock depend on its parent rock (the original rock type) and how it was formed. (Web site)

Three Main Rock Types

1. Sedimentary rock is one of the three main rock types (the others being igneous and metamorphic rock).

Foliated Metamorphic Rock

1. For example, a protolith shale will yield a foliated metamorphic rock, and a protolith limestone will yield marble, a non-foliated metamorphic rock.

Result

1. Marble - Marble is a metamorphic rock which can result from regional or contact metamorphism. (Web site)
2. The result is a true metamorphic rock, called metaquartzite. (Web site)

Grains

1. Schist - A foliated metamorphic rock the grains of which have a roughly parallel arrangement; generally developed by shearing.

Heated

1. A true metamorphic rock, since it's heated beyond the temperatures found in normal sedimentary burial. (Web site)

Composition

1. Schist - A medium or coarse-grained metamorphic rock with subparallel orientation of the micaceous minerals which dominate its composition. (Web site)

Geology

1. The exposed geology of the Yosemite area includes primarily granitic rocks with some older metamorphic rock.

Intense

1. Metamorphic rock - A rock which has been altered by heat or intense pressure, causing new minerals and structures to be formed.

Pressures

1. Outcrop of a metamorphic rock (a gneiss) that has experienced high temperatures and pressures.
2. Gneiss is a high grade metamorphic rock, meaning that it has been subjected to higher temperatures and pressures than schist. (Web site)

Change

1. Metamorphic rock can also change into the other kinds of rock. (Web site)
2. Additional eroded rocks may bury these layers until heat and pressure change the underlying layers to metamorphic rock.

Dolomite

1. Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite.
2. Marble A metamorphic rock consisting mostly of metamorphosed limestone or dolomite. (Web site)

Cleavage

1. Foliation: Any planar set of minerals or banding of mineral concentrations including cleavage, found in a metamorphic rock.

Continental Crust

1. Continental crust is primarily granitic in composition, overlain by sedimentary and metamorphic rock s.

Hornblende

1. Amphibolite - A metamorphic rock consisting chiefly of hornblende, or of at least one member of the amphibole group of minerals.

Layered

1. Gneiss refers to a coarsely foliated (layered) metamorphic rock.
2. Gneiss - A layered or banded crystalline metamorphic rock, the grains of which are aligned or elongated into a roughly parallel arrangement.

Igneous Rock

1. Igneous rock (etymology from Latin ignis, fire) is one of the three main rock types (the others being sedimentary and metamorphic rock).

Red-Brown

1. Tiger's Eye - Tiger's eye is a chatoyant gemstone that is usually a metamorphic rock that is a golden to red-brown color, with a silky luster. (Web site)

Zoisite

1. Though considered a variety of zoisite, strictly speaking it is a metamorphic rock composed of intergrown green zoisite, black hornblende and ruby.

Anyolite

1. Anyolite (metamorphic rock - zoisite, ruby, and hornblende) 12.
2. Found in Kenya and Tanzania, anyolite is actually a metamorphic rock composed of intergrown green zoisite, black hornblende, and ruby.

Canada

1. Types of metamorphism Contact metamorphism A contact metamorphic rock made of interlayered calcite and serpentine from the Precambrian of Canada. (Web site)

Acasta Gneiss

1. The Acasta Gneiss is a metamorphic rock about 4 billion years old.

Quartz

1. Gneiss (pronounced "nice") is a metamorphic rock consisting mostly of quartz and feldspar and showing distinct layering or banding. (Web site)
2. Quartzite - A metamorphic rock consisting largely or entirely of quartz. (Web site)

Skarn

1. A skarn is a metamorphic rock that is usually variably colored green or red, occasionally grey, black, brown or white.

Soapstone

1. Soapstone or Steatite is a metamorphic rock that comes in degrees of hardness.

Sedimentary Rock

1. These processes move rock material through the states of metamorphic rock, igneous rock, sedimentary rock, melts and sediment. (Web site)
2. The protolith may be sedimentary rock, igneous rock or another older metamorphic rock. (Web site)

Form

1. Skarn: This is a metamorphic rock that can form in several ways through alteration of country rock.
