Metamorphism is the process by which rocks change in composition, texture, or structure due to extreme heat and pressure. There are six main types of metamorphism: regional metamorphism, contact metamorphism, burial metamorphism, seafloor metamorphism, subduction zone metamorphism, and shock metamorphism. Regional metamorphism occurs when rock layers are compressed, folded, and buried deep underground. Contact metamorphism happens when magma intrudes into the upper crust near rock layers. Burial metamorphism takes place when sediments are buried deeply enough that heat and pressure cause mineral recrystallization and growth.

Plate tectonics and magma genesis
The document discusses plate tectonics and magma genesis. It describes how the Earth's crust is divided into 12 major plates that move in various directions, causing them to collide, pull apart, or scrape against each other. It also explains that magma can only be created at plate boundaries where there are significant local changes in pressure and temperature. The three main types of plate boundaries are divergent boundaries, where plates separate and new crust is formed; convergent boundaries, where plates collide and one slides under the other; and transform boundaries, where plates slide past each other.

METAMORPHISM ; CONTROVERSIAL ISSUES REGARDING HIMALAYAN METAMORPHISM & RECENT...
The document discusses metamorphism in the Himalayas, specifically addressing controversial issues regarding Himalayan metamorphism and recent research in Nepal. It describes the different types of metamorphism that can occur, including regional, contact, and inverted metamorphism. In the Nepal Himalayas, inverted metamorphism is observed, where higher grade metamorphic rocks overlie lower grade rocks. Possible explanations for this include shear heating along fault zones and heat diffusion from hotter rocks thrust over colder rocks.
Paired metamorphic belts
Paired metamorphic belts occur where zones of high-pressure low-temperature metamorphism are parallel to zones of low-pressure high-temperature metamorphism. They were first recognized in Japan and form due to subduction of oceanic crust beneath continental crust. Paired metamorphic belts support the theory of plate tectonics, as the contrasting pressure-temperature conditions in the two parallel belts can be explained by ocean-continent convergence. Examples of paired metamorphic belts are found throughout the basement rocks of the former Gondwanaland supercontinent.
5.4 metamorphic rock
Metamorphic rocks are formed from existing igneous, sedimentary, or other metamorphic rocks by heat, pressure, and chemical processes deep beneath the Earth's surface. There are two types of metamorphism: contact metamorphism near magma intrusions, and regional metamorphism caused by heat and pressure during tectonic plate movement, most commonly resulting in chemical changes to the rocks. Metamorphic rocks can be classified as either foliated or nonfoliated based on their texture.
Origin& evolution of magma ,magmatism related to plate tectonics.
This document summarizes a seminar on the origin and evolution of magma and its relationship to plate tectonics. It discusses how magma originates from partial melting of the solid earth due to increased temperature and pressure. Magma composition evolves through processes like fractional crystallization, assimilation, and magma mixing. Magmatism is related to plate tectonics through mechanisms like decompression melting at mid-ocean ridges and continental rifts, flux melting near subduction zones, and intraplate volcanism from mantle plumes not associated with plate boundaries. Examples discussed include the Deccan Traps basalts formed by a mantle plume in India.
Metamorphism and types of metamorphism
Metamorphism refers to the process of changes in pre-existing rocks caused by exposure to high pressures and temperatures. There are several types of metamorphism that result from different conditions, including contact metamorphism near igneous intrusions, regional metamorphism during mountain building, and subduction-related metamorphism at convergent plate boundaries. Key agents that control metamorphism are heat, pressure, chemical activity, and fluid phases, which can cause changes in minerals, textures, and introduce new mineral assemblages over long periods of time. Metamorphic grade describes the temperature and pressure conditions, ranging from low-grade to high-grade metamorphism.

Plate tectonics and Magma genesis
This document discusses plate tectonics and magma genesis. It summarizes that the Earth's crust is divided into 12 major tectonic plates that move in different directions, interacting through collision, separation, or sliding past each other. These plate boundary interactions cause volcanism and earthquakes. Magma is generated through partial melting of the mantle at divergent boundaries due to upwelling or at convergent boundaries through dehydration of subducted oceanic crust.
Petrology
The document provides information about petrology, which is the study of rocks. It discusses the structure of the Earth and defines rocks as aggregates of minerals. Rocks are classified based on their geological origin as igneous, sedimentary or metamorphic. Igneous rocks form from the solidification of magma or lava and include intrusive and extrusive types. Sedimentary rocks form from the compaction or cementation of sediments derived from pre-existing rocks by weathering processes. The document outlines the formation of magma from heat and pressure conditions in the Earth's interior and how magma crystallizes into igneous rocks as it cools on the surface or in the crust.
6-Metamorphic-Rocks.pdf
Metamorphic rocks are formed from the alteration of pre-existing rocks, such as igneous or sedimentary rocks, under high pressures and temperatures within the Earth. There are three main types of metamorphism - contact, regional, and cataclastic - which result in different textures and mineral compositions in the metamorphic rocks. Metamorphic rocks can be classified based on their textures as either foliated, containing aligned platy minerals, or non-foliated, and by their mineral composition. Common metamorphic rocks include slate, phyllite, schist, gneiss, marble, quartzite, and amphibolite.
MAGMATISM.pptx
Magma is molten rock located beneath the Earth's surface, specifically in the mantle and oceanic plates. Magma forms through the process of partial melting when rocks are exposed to high temperatures and pressures in the lower crust and upper mantle. The top two compositions of magma are silica and magnesium/iron. Magma is formed through three main processes: an increase in temperature through heat transfer, a decrease in pressure through decompression melting as rocks rise, and the addition of volatile materials like water and carbon dioxide which lowers the melting point during flux melting.
Lecture 4
The document summarizes the rock cycle and how rocks are formed and changed over time through various geological processes. It describes how igneous rocks can be changed into sedimentary and metamorphic rocks through weathering and lithification of sediments. Sedimentary rocks can then be changed into metamorphic rocks through heating and compression. Metamorphic rocks can partially melt to form new igneous rocks. All of these processes are interconnected and operate in a continuous cycle that is driven by tectonic activity and the interplay between internal and external forces shaping the Earth's surface.
Chapter 2.in geomorphology
This document provides an overview of structural geomorphology and the key surface and subsurface processes that shape the Earth's landscapes. It discusses global geomorphology and the intersection between climatic, hydrologic, and biologic surface processes with underlying geologic processes. Specific topics covered include plate tectonics and the different landforms that form at divergent, convergent and transform plate boundaries. The document also discusses weathering processes, the factors that influence them, and characteristic landforms formed by weathering such as exfoliation domes and rock basins. Finally, it covers slope stability and the different types of landslides that can occur based on material type and movement.
Methamorphic Rocks
This document provides an overview of metamorphic rocks, including the processes of metamorphism, common structures and textures, classification, and descriptive study of common metamorphic rocks. Metamorphism involves changes to pre-existing rocks due to heat, pressure, and chemically active fluids. This causes changes in mineral composition and texture. Common structures that form include foliation and lineation due to alignment of minerals. Metamorphic rocks are classified based on their protolith and degree of metamorphism experienced. Examples of commonly studied metamorphic rocks described include quartzite, marble, slate, gneiss, and schist.
Metamorphic rocks
The document discusses different types of metamorphism including contact metamorphism, regional metamorphism, and cataclastic metamorphism. It also describes the agents of metamorphism including temperature, pressure, and water. Temperature can come from magma or increasing depth, while pressure includes lithostatic pressure from overburden and stress from tectonic forces. Metamorphism results in changes to mineral composition and texture of rocks.
The rock cycle
The rock cycle describes how rocks change form over long periods of time through various physical processes. There are three main types of rocks - igneous, sedimentary, and metamorphic - and each can change into another through the processes of cooling, weathering and erosion, compaction and cementation, heat and pressure (metamorphism), and melting. The rock cycle begins with molten rock that cools to form igneous rock. Erosion produces sediment that is buried and compacted into sedimentary rock. Further burial and heat causes metamorphism into metamorphic rock, which at high heat and pressure can melt back into magma to restart the cycle.
Metamorphic rock
Metamorphic rocks form from intense heat and pressure that alter igneous, sedimentary, or existing metamorphic rocks. This process occurs deep underground where overlying rock layers exert pressure and heat is present but not enough to melt the rock. Minerals may rearrange or new minerals may form as the rock changes form. Metamorphic rocks are classified as either foliated, with flattened and aligned mineral grains, or non-foliated with no banded structure. They typically form near mountain ranges where tectonic plates collide or where thick piles of overlaying rock cause high pressure.
Metamorphic rocks process of formation 2014
This document discusses how metamorphic rocks are formed and classified. Metamorphic rocks form deep underground through heat and pressure changing existing rocks. They are classified based on their texture into either foliated rocks, which have layers or bands, or non-foliated rocks, which lack layers or bands. Common foliated metamorphic rocks include slate, phyllite, schist and gneiss, while common non-foliated rocks include quartzite and marble.

Metamorphic Rocks geology
Metamorphic rocks form from existing igneous, sedimentary, or other metamorphic rocks when they are subjected to high heat, pressure, fluids, or a combination of these deep within the earth or at tectonic plate boundaries. The process of metamorphism transforms rocks into more compact and denser varieties with new minerals formed through rearrangement or chemical reactions. Metamorphic rocks make up a large portion of the earth's crust and studying them provides insight into deep temperatures and pressures within the earth.
Evolution of Magma.pdf
This document discusses the evolution of magma from its formation to solidification. It begins by defining magma and describing its components. Magma forms by partial melting in the mantle or crust and can evolve as it rises towards the surface. Factors like temperature, pressure, and composition determine magma type and influence processes like fractional crystallization that change magma chemistry over time. Magma may erupt as lava or cool underground to form intrusive rocks. Overall, the document provides a comprehensive overview of magma origins and differentiation, and how these processes ultimately lead to the formation of igneous rocks.
Evolution of magma
- Magma forms by partial melting of the mantle or crust and consists of molten or semi-molten rock. It varies in temperature, pressure, density and composition depending on its origin and evolution.
- Magma evolves as it differentiates through fractional crystallization, assimilation, and mixing. Early crystallizing minerals remove elements from the magma, changing its composition over time according to Bowen's reaction series.
- Magma rises towards the Earth's surface where it cools and crystallizes to form either plutonic or volcanic rocks, depending on the cooling rate. Slow cooling results in large mineral crystals in plutonic rocks, while rapid cooling of lava forms volcanic rocks like obsidian with little

Ch04 igneous rocks-fall2007
This document discusses the formation of igneous rocks. It explains that igneous rocks form from the crystallization of magma or lava as it cools. Magma originates from the partial melting of rocks in the Earth's mantle or crust due to increased heat, decreased pressure, or the presence of volatiles like water. As magma cools, minerals crystallize out in a predictable order described by Bowen's Reaction Series. The composition of magma evolves as it cools through processes like fractional crystallization. Igneous rocks range from basalt to andesite to granite depending on their origin and evolution.

Rocks
There are three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling and solidification of magma either below or above the ground. Sedimentary rocks form from the compression of sediments and organic materials. Metamorphic rocks form from the alteration of existing igneous and sedimentary rocks through heat, pressure, and chemical changes. Rocks continuously change between these forms through the rock cycle as they are weathered, buried deep underground, and altered by melting.

- 5. Regional metamorphism • During regional metamorphism, rock layers are compressed, folded and buried.
- 9. • This happens when a body of magma intrudes into the upper part of the crust. Contact metamorphism
- 11. • This occurs when sediments are buried deeply enough that the heat and pressure cause minerals to begin to recrystallize and new minerals to grow.
- 12. • An oceanic spreading ridge, recently formed oceanic crust of gabbro and basalt is slowly moving away from the plate boundary.
- 14. • Where ocean lithosphere is forced down into the hot mantle, there is a unique combination of relatively low temperature and very high pressure.
- 18. • When extraterrestrial object hit Earth, the result is shock wave.
- 21. • Result of very high shear stress such as occurs along fault zone. It occurs at relatively low temperatures compared to other types of metamorphism.
