Metamorphic Rocks pages.geo.wvu.edu

Metamorphic rocks can be formed from any rock type igneous, sedimentary, or existing metamorphic rocks. Involves recrystallization in the solid state, often with little change in overall chemical composition. Driving forces are changes in temperature, pressure, and pore fluids. Regional Metamorphic Zones.

The Rock Cycle Igneous, Sedimentary, and Metamorphic

The rock cycle is a continuous process describing the transformation of the rocks through various stages through their lifetime. The rock cycle simply moves from the igneous to metamorphic to sedimentary rocks and the process repeats itself over and over.

Regional Metamorphic Rocks Collecting Rocks and Minerals

Regional metamorphic rocks are the rocks with the typical schisty look. They have layers that easily break off. As opposed to contact metamorphic rocks, the regional ones have been formed by both pressures and temperatures. They form the slate phyllite schist gneiss series.

Types of Metamorphism

Metamorphic grades. The different groups of minerals, or assemblages, that crystallize and are stable at the different pressure and temperature ranges during regional metamorphism distinguish distinct metamorphic grades, or faces. The grades are usually named for the dominant minerals or colors that identify them (Figure 1).

The metamorphic cycle is the third largest cycle in mineral and rock formation. Metamorphism is the alteration of mineral paragenesis (the order of formation) after their deposition, by external action such as contact with magmetic rocks, regional changes in the pressure and temperature (e.g. contact metamorphosed limestones, crystalline schists, etc.).

Types of metamorphism The Australian Museum

Regional metamorphism. Most metamorphic rocks occur in fold mountain belts or cratonic areas. Such rocks cover large areas of the Earth's crust and are therefore termed regional metamorphic rocks. They arise by the combined action of heat, burial pressure, differential stress, strain and fluids on pre-existing rocks.

CHAPTER 8 (Metamorphic Rocks)

1. Metamorphic rocks are those rocks that have undergone changes in mineralogy, texture and/or chemical composition as a result of changes in temperature and pressure. The original rock may have been igneous, sedimentary or another metamorphic rock. 2. The pressure and heat that drive metamorphism

How Is Metamorphic Rock Formed? Reference

Metamorphic rock is formed underground through a process that changes a rock's molecular structure due to pressure, heat and chemical reactions. A metamorphic rock forms from a parent rock called a protolith. Depending on conditions, a protolith can transform into any metamorphic rock. Because protoliths are capable of undergoing vast changes

Regional metamorphism, or dynamic metamorphism, occurs in great masses of rock. Rocks can be metamorphosed just by being at great depths below the Earth's surface. There they get high temperatures and the great weight of the rock layers above. Much of the lower continental crust is metamorphic, except for recent igneous intrusions.
