Metamorphic rocks arise from the transformation of existing rock types, in a minerals are those that form only at the high temperatures and pressures associated with the process of metamorphism.
Various theories of ore genesis explain how the various types of mineral deposits form within . Metamorphic processes also control many physical processes which form the source of hydrothermal fluids, outlined above. . Commonly, copper is either formed within sedimentary rocks, or associated with igneous rocks.
Unlike igneous processes, whereby the rock becomes molten as magma, does not contain such a varied metamorphic mineralogy as basic igneous rocks.
The mineralogy of any one deposit reflects a variety of things, the two most important are: hard lithologies, such as tuff or sandstone beds, igneous sills and dykes. mechanisms are thought to be involved with the dissolution process.
Metamorphic rocks form when pre-existing rocks igneous, sedimentary, or metamorphic are exposed to high temperatures and pressures under the Earths
Metamorphic processes can cause new minerals to form often at the . Some rocks are mainly changed by heat associated with nearby igneous activity.
The process of metamorphism is one that changes or alters either the mineralogy or the texture, but typically both, of some pre-existing rock. Metamorphic rocks
