What Are the Three General Types of Rocks? | .

Metamorphic rocks are rocks that have gradually changed from one rock type to another. This occurs when a rock is placed in an environment that causes its minerals to change, usually due to high temperature or pressure. Rocks that are buried and changed by heat and gradual pressure are referred to as foliated, or layered, metamorphic rocks. Over time, the increased pressure of burial will ...

style and metamorphic history. In most of these rocks, the degree of deformation is intense and is of high metamorphic grades. They were thus referred to earlier in literature as the basement system rocks, due to high degree of metamorphism and deformation. Recent work on the Mozambique Belt has shown that rocks can be sub-divided into groups of contrasting lithology, structure and composition ...

Metamorphism - Wikipedia

Metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (), without the protolith melting into liquid magma (a solid-state change). The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. The chemical components and crystal structures of the minerals making up the rock may change even ...

Metamorphic rocks are rocks that have been changed by heat or pressure, or both. Originally, they were either igneous or sedimentary rocks. They may form when buried rocks are squeezed, folded, and heated as mountain ranges are pushed up from Earth's crust (outer layer). Other metamorphic rocks form when the rocks surrounding super-hot igneous rocks are baked by the high temperatures.

Metamorphic Rocks: Meaning and Classification

Since metamorphic rocks can be formed from any type of existing rocks, their mineral composition ranges more widely than that of all other types of rock. They cannot be covered by a simple scheme of classification, but a simple textural classification is given below. It is important to note that most metamorphic rocks are anisotropic (having different properties in different directions). Thus ...
