Metamorphic rocks PDF

During metamorphism, rocks may fold, fracture, or even partially melt to a viscous state and flow before reforming into a new rock. Metamorphic rocks change in appearance, mineralogy, and sometimes even chemical composition from their parent rock source. 6 Table of Contents Metamorphic Rocks Metamorphic rocks and processes • Metamorphism comes from the Greek words Meta - change Morphe - form • Metamorphic rocks form by solid-state (no melting) transformation of preexisting rock by processes that take place beneath Earth's surface. • Chemical, mineralogical and structural adjustments o

Metamorphic Rocks • Metamorphic rocks are classified on the basis of texture and composition (either mineralogical or chemical) • Unlike igneous rocks, which have been plagued by a proliferation of local and specific names, metamorphic rock names are surprisingly simple and flexible • May choose some prefix-type modifiers to attac Metamorphic rocks are igneous, sedimentary, or other metamorphic rocks whose texture and composition has been changed by metamorphism. Metamorphism occurs as a response to changes in the physical or chemical environment of any pre-existing rock, such as variations in pressure or temperature, strain, or the infiltration of fluids. I

It covers plate tectonics, the formation of mountains, and varieties of metamorphic rocks such as gneiss, slate, fulgurite, quartzite, marble, schist, and hornfels Metamorphic rocks exhibit a variety of textures. These can range from textures similar to the original protolith at low grades of metamorphism, to textures that are purely produced during metamorphism and leave the rock with little resemblance to the original protolith. Textural features of metamorphic rocks have been discussed in the previous.

reactions during retrograde metamorphism. Metamorphic Rock Types There are two major subdivisions of metamorphic rocks. 1. Foliated - These have a planar foliation caused by the preferred orientation (alignment) of minerals and formed under differential stress. They have a significant amount of sheet silicate (platy minerals and are classified b metamorphic rocks. Metamorphic rocks are best identified when looking at the rock as you see them in nature. You can clearly see the deformation and features that are characteristic of an entire area. Metamorphic rocks were once sedimentary, igneous, or another metamorphic rock. These rocks are physically deformed and chemically changed due t

Metamorphism is the process of mineralogical and structural changes of rocks in their solid state in response to physical and chemical conditions (pressure, temperature and chemistry). Metamorphism occurs at higher pressure and temperature than weathering and diagenetic processes. Metamorphism encompasses all solid-state changes in th Structures in Metamorphic Rocks: The structures of the metamorphic rocks are: (i) Slaty structure, (ii) Schistose structure, (iii) Gneissose structure, and (iv) Granulose structure. (i) Slaty structure: The slaty structure is also called slaty cleavage. The rock possessing slaty cleavage has a unique property of splitting into thin sheets

Metamorphic rocks may have either foliated (layered) or non-foliated texture. Foliated texture is a pervasive layering caused by compositional layering or by the parallel orientation of platy (e.g, mica) or elongate (e.g., amphibole) mineral grains.

Uses of Metamorphic Rocks. Quartzite and marble are the most commonly used metamorphic rocks. They are frequently chosen for building materials and artwork. Marble is used for statues and decorative items like vases (Figure). Quartzite is very hard and is often crushed and used in building railroad tracks. Schist and slate are sometimes used as. the composition of the original rock, the grade or intensity of metamorphism, and the kinds of chemical substances either removed or introduced during metamorphism.

Q. 'Explain the formation of metamorphic rocks, with reference to examples from Ireland' (2013 Q1 B.) Metamorphic rocks are formed when igneous or sedimentary rocks change due to the fact they have been put under great heat or pressure or both. The first type of metamorphism is Thermal metamorphism, this is when rocks are changed as a result o Metamorphic rocks. 1. Dr. V. R Ghodake Sinhgad College of Engineering, Vadgaon (Bk), Pune. Email- vyanky.g@gmail.com Mobile- 9764484757. 2. They are altered or changed beyond their recognition, i.e. change in Chemical composition, texture and structure When rocks are baked by heat of molten magma or squeezed by the movements of huge tectonic. Igneous, Sedimentary vs. Metamorphic Rocks: The main difference between Igneous, Sedimentary and Metamorphic rocks is the way that they are formed, and their various textures.Igneous Rocks: Igneous rocks are formed when magma (or molten rocks) cool down, and become solid. High temperatures inside the crust of the Earth cause rocks to melt, and this substance is known as magma In that case, you will end up with the entire rock having minerals aligned in a certain direction, all by the breaking of bonds between atoms in a mineral, and reforming (recrystallizing) in the lower pressure areas among the grains or crystals in the rock. The end result is a rock with a metamorphic pattern called a foliation. Metamorphic. The usage of some common terms in metamorphic petrology has developed differently in different countries and a range of specialised rock names have been applied locally. The Subcommission on the Systematics of Metamorphic Rocks (SCMR) aims to provide systematic schemes for terminology and rock definitions that are widely acceptable and suitable for international use
