Marble is a metamorphic rock resulting from regional or at times contact metamorphism of sedimentary carbonate rocks, either limestone or dolostone. This metamorphic process causes a complete recrystallization of the original rock into an interlocking mosaic of calcite and/or dolomite crystals.

Metamorphic rock - Wikipedia

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 change.The protolith may be a sedimentary, igneous, or existing metamorphic rock.

The resulting metamorphic rock is formed under very high pressures, but the temperatures are relatively low. Remember that rock that are formed by regional metamorphism are foliated. In general, the greater the pressure and temperature changes in the rock, the coarser grained the rock is.

Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word "metamorphic" comes from Greek and means "To Change Form".

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.

Nov 15, 2018 · Non-foliated metamorphic rocks can also be formed by contact metamorphism, where significant heat is added to the protolith but not pressure. This results in a baking of the protolith rather than compression, which allows the crystals within the rock to reorganize freely. The resulting metamorphic rock may not have any observable mineral pattern.

The resulting silica-rich liquid will invade the partially melted rock as a series of veins and stringers to produce a migmatite. 7.

METAMORPHIC ROCKS - oakton.edu

Contact (heat-dominated) metamorphism occurs when molten rock (magma) comes into contact with other surrounding rocks (called the country rock). The heat causes a localized "baked zone" of metamorphosed rock. Metamorphic rocks produced by contact metamorphism are not foliated, as the major factor here involves heat rather than pressure.

Marble is a metamorphic rock resulting from the heating of limestone or dolostone. The heating may be regional due to the subduction of a limestone or may be the result of contact metamorphism where a magma intrudes into a limestone, resulting in partial melting.

Slate, schist, and gneiss are three common foliated metamorphic rocks. Slate is a hard, fine-grained rock with a well-developed rock cleavage or slaty cleavage caused by the incipient growth of platy (micaceous) minerals, due to metamorphism of fine-grained clastic sediments such as shale and siltstone and also volcanic tuffs.

7.2 Classification of Metamorphic Rocks – Physical Geology

7.2 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.

Mylonite is a fine-grained metamorphic rock, typically banded, resulting from the grinding, shearing, or crushing of other rocks in a fault zone (Figure 11-46). Fault zones are places where fluids can move through, enhancing the processes of metamorphism.
