The following is a list of rock types recognized by geologistsThere is no agreed number of specific types of rocks Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type
Metamorphic rock, any rock that results from the alteration of preexisting rocks in response to changing conditions, such as variations in temperature, pressure, and mechanical stress, and the addition or subtraction of chemical components The preexisting rocks may be igneous, sedimentary, or other metamorphic rocks
May 10, 2019· Metamorphic rocks are an important topic in geology These are the rocks that form by the effects of heat, pressure, and shear upon igneous and sedimentary rocks Some form during mountain-building by forces of others from the heat of igneous intrusions in regional metamorphism others from the heat of igneous intrusions in contact metamorphism
Metamorphic rocks always seem to get the shortest treatment in introductory geology class This is unfortunate, because metamorphic rocks form right where the action is: in the hearts of mountain belts during continental collisions, along subduction zones as the slabs grind ever deeper below the .

72 Classification of Metamorphic Rocks There are two main types of metamorphic rocks: those that are foliated because they have formed in an environment with either directed pressure or shear stress, and those that are not foliated because they have formed in an environment without directed pressure or relatively near the surface with very little pressure at all
Schist is a metamorphic rock that is commonly formed when sedimentary, volcanic igneous, or low-grade metamorphic rock is subjected to moderately high temperatures and pressures during regional metamorphism These conditions result in the aligned growth of micaceous minerals and give schist a reflective or shiny appearance
Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form" The original rock is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical changeThe protolith may be a sedimentary, igneous, or existing metamorphic rock
Nov 27, 2019· Metamorphic rocks are formed when a preexisting rock, called a protolith, is under conditions of high heat and pressure, causing it to metamorphose chemically, structurally, or both The protolith might be an igneous, sedimentary, or another metamorphic rock Slate, marble, and quartzite are some examples of this type
Metamorphic Rock Resourc Metamorphic rock is rock that has changed from one type of rock into another The word metamorphic (from Greek) means “ of changing form ” Metamorphic rock is produced from igneous rock (rock formed from the cooling and hardening of magma), sedimentary rock (rock formed from compressed and solidified layers of organic or inorganic matter), or existing .
