Types of Metamorphic Rocks Coming up with a way to classify and name the great variety of metamorphic rocks on Earth hasn t been easy After decades of debate geologists have found it most convenient to divide metamorphic rocks into two fundamental classes foliated rocks and non foliated rocksMetamorphic rocks started out as some other type of rock but have been substantially changed from their original igneous sedimentary or earlier metamorphic form Metamorphic rocks form when rocks are subjected to high heat high pressure hot mineral rich fluids or

A list of all unique rock types recognized by petrologists Names of non rock types and archaic rock types are given as appendic Contents show Igneous tells you Andesite an Intermediate volcanic rock Anorthosite an intrusive igneous felsic rock composed predominantly of plagioclase Metamorphic rocks are classified by texture and by mineral composition Foliated metamorphic rocks If a rock is foliated its name is determined by the type of foliation present and the dominant minerals—for example a kyanite schist If the minerals are segregated into alternating light‐colored and dark‐colored layers the rock is called a gneiss

Types of Rocks Geologists classify rocks into three main groups igneous rock sedimentary rock and metamorphic rock Metamorphic Rock is formed by heat and pressure from other rocks Depending on how the rock formed rocks can be igneous sedimentary or metamorphic Igneous RockJan 25 32 Metamorphic rocks can be divided on the basis of their metamorphism regional thermal hydrothermal and fault zone metamorphism Regional metamorphic rocks are found in the mountainous regions and are developed in accordance to the

Types of Metamorphic Rocks Metamorphic rock fall into two categories foliated and unfoliated Most foliated metamorphic rocks originate from regional metamorphism Some unfoliated metamorphic rocks such as hornfels originate only by contact metamorphism but others can originate either by contact metamorphism or by regional metamorphismSlate is a metamorphic rock Metamorphic rocks are formed when sedimentary or igneous rocks are exposed to conditions of very high pressure or temperature or are exposed to large amounts of very hot water Slate is formed when fine grained sedimentary rock shale is buried and exposed to high pressure deep beneath the Earth s surface

72 Classification of Metamorphic Rocks There are two main types of metamorphic rocks those that are foliated because they have formed in an environment with either directed pressure or shear stress and those that are not foliated because they have formed in an environment without directed pressure or relatively near the surface with very little pressure at allPhotographs and information for a large collection of igneous metamorphic and sedimentary rocks Geology

Metamorphic — they are formed through the change metamorphosis of igneous and sedimentary rocks They can form both underground and at the surface They can These conditions often stretch twist and fold the rock as it cools In metamorphic rocks some or all of the minerals in the original rock are replaced atom by atom to form new minerals Types of metamorphic rocks include gneiss quartzite marble schist soapstone and phyllite Parks with examples of metamorphic rocks include
