Contact Metamorphism - an overview | ScienceDirect Topics

Contact metamorphism is often described using subdivisions of the low-pressure hornfels facies (Fig. 1), although the eponymous minerals used to define this sequence, such as hornblende, do not always form in metapelites due to their Al-rich and Ca-poor bulk composition (Table 1).Nonetheless, these sub-facies have use in describing the relative intensity of metamorphism.

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.

Metamorphic Rocks – Definition, Formation, Types, & Examples

1. Contact Metamorphism: Occurs when magma comes in contact with an already existing body of rock. When it forms, the current temperature in rocks rises and becomes infiltrated with magma fluid. The area affected is usually small, from 1 to 10 kilometers. Contact metamorphism produces non-foliated rocks such as marble, quartzite, and hornfels. 2.

Marble is the metamorphism of limestone. Marble forms from the metamorphism of limestone or dolostone. The metamorphism occurs as a result of exposure to heat and pressure over large expanses of time.

Metamorphic Rocks

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.
