22/04/2011  The first is modally dominated by dolomite (CaMg(CO 3) 2), the second by calcite (CaCO 3) and there is a complete gradation between the pure dolomite and limestone “end members” indicated by the rock names, calcitic dolomite, dolomitic limestone, magnesian limestone. As the rocks often also contain variable amounts of quartz they are sometimes referred to as siliceous dolomites and ...

Geological Society - Regional

Regional metamorphism affects large volumes (regions) of rock, especially in the mountain chains that form when continents collide. Regionally metamorphosed rocks usually have a squashed, or foliated appearance – examples include slate, schist and gneiss (pronounced “nice”), formed by metamorphism of mudstones, and also marble which is formed by metamorphism of limestone.

Types of Metamorphism - Tulane University

Regional metamorphism occurs over large areas and generally does not show any relationship to igneous bodies. Most regional metamorphism is accompanied by deformation under non-hydrostatic or differential stress conditions. Thus, regional metamorphism usually results in forming metamorphic rocks that are strongly foliated, such as slates, schists, and gniesses. The differential stress usually ...

Dolomite: A sedimentary rock known as dolostone or ...

Metamorphism of Dolomite. Dolomite behaves like limestone when it is subjected to heat and pressure. It begins to recrystallize as the temperature rises. As this occurs, the size of the dolomite crystals in the rock increases, and the rock develops a distinctly crystalline appearance.

Contact Metamorphism of Dolomite and Calcite limestone Dolomitic and calcitic limestone sediments may also be metamorphosed by adding heat from an igneous heat source at shallow levels in the crust. Commonly, the intrusive body is of granitic, granodioritic or quartz-dioritic composition and the temperature at the contact to the country rocks is in the order of 600-700 °C.

Dolomitic Marble

25/10/2000  Recrystallized dolomitic limestone producing interlocking grains of dolomite. Marble, both limestone and dolomitic, is an extremely variable rock in appearance since it depends on what rock was the parent, and the degree of metamorphism it underwent. It can be virtually any color from white to black to red to green, etc., and sometimes it will contain metamorphosed fossils or other

Marble: Metamorphic Rock: Pictures, Definition, Properties

Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals. A related rock, dolomitic marble, is produced when dolostone is subjected to heat and pressure. Photo Gallery: The Many Uses of Marble. Ruby in Marble: Marble is often the host rock for corundum, spinel, and other gem minerals. This specimen is a ...

Examples of Metamorphic Changes in Rocks Geology

In regional metamorphism, however, when the heat factor is actively associated with pressure and chemically active fluids, granites and other related igneous rocks show very considerable and conspicuous changes. ADVERTISEMENTS: They may pass through a flaser-rock type stage under the influence of directed stress and suffer simultaneous and substantial recrystallisation due to intense
