Metamorphic Rocks

Regional (pressure-dominated) metamorphism occurs over large areas during periods of mountain building. Regional metamorphism causes a layered or platy structure in rocks, called foliation . Foliated rocks are the result of intense pressure (and sometimes, to a lesser degree, are also the result of heat).

Marble: Metamorphic Rock: Pictures, Definition, Properties

What is Marble? Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form a rock that is ...

Limestone and dolomite - Earth Resources

Limestone and dolomite have been formed in a variety of settings in Victoria and range in age from early Palaeozoic to Quaternary. Younger limestones tend to be friable and porous, whereas older limestones are often dolomitised and silicified, or metamorphosed and recrystallised to marble.

Regional metamorphism is most associated with convergent plate boundaries (past and present), and particularly between colliding continental landmasses (Figure 10-20). Continental collisions causes metamorphism to take place on a regional scale. In general, the deeper a rock moves into the crust, the greater degree of metamorphism it endures.

What major change occurs during metamorphism of limestone ...

Nov 06, 2009· Marble is a metamorphic rock resulting from regional or, rarely, contact metamorphism of sedimentary carbonate rocks (either limestone or dolomite rock) or metamorphism of older marble. This metamorphic process causes a complete recrystallization of the original rock into an interlocking mosaic of calcite, aragonite and/or dolomite crystals.

Dolomitic Marble

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.

Skarn - Wikipedia

In many cases, skarns are associated with the intrusion of a granitic pluton found in and around faults or shear zones that intrude into a carbonate layer composed of either dolomite or limestone. Skarns can form by regional, or contact metamorphism and therefore form in …
