2. Most metamorphic petrologists agree that the simplicity of patterns observed during dehydration reactions of noncarbonate sediments and loss of CO 2 from highly calcareous sediments suggests that partial pressures of the dominant gases and total pressures (load pressure) acting in the system are not completely independent. The “typical” or average continental geotherm is from Brown and Mussett (1993). The sillimanite grew by the reaction muscovite + quartz = sillimanite + K-feldspar + H 2 O. Prentice Hall.

There are many ways to approach this question and the answer can sometimes be quite elusive. Some properties of water are evaluated, such as its dielectric constant and ionic product, at high pressures and temperatures. Metamorphic Reactions 1 Metamorphic Reactions and Stable Assemblages Metamorphic Lecture 3 Eskola and Metamorphic Facies • Eskola (1914, 1915) noted that metapelitic rocks in southern Finland (Orijärvi) contained the assemblage Bt-Ms whereas near Oslo, rocks contained the compositionally equivalent mineral assemblage Kf-Cd Polymorphic phase transformation. 2 0 obj 0000001002 00000 n Examples include the production of talc under varied metamorphic conditions: All papers deal with natural processes that As we discussed previously, the fluid phase plays an important role in metamorphic reactions. metamorphic minerals is commonly localized in shear zones. Small amounts of muscovite in the foliation are still present, so the reaction did not run to completion. • The chemical reactions involved in metamorphism are relatively slow • The longer the metamorphic event lasts the larger the grain size • It is thought that coarse grained metamorphic rocks took millions of years to form • But temperature, pressure and fluid content are more important O) and, – transport and exchange of substances and heat between domains where such reactions take place endobj Metamorphic petrology covers the chemical and physical work done in natural systems in response to changing physical conditions.

A very simple mineralogical system and its response to changing pressure and temperature provide a good illustration of what occurs in metamorphism.An uncomplicated sediment at Earth’s surface, a mixture of the clay mineral kaolinite [Al 4 Si 4 O 10 (OH) 8] and the mineral quartz (SiO 2), provides a good example. 0000000981 00000 n Metamorphic processes also commonly drive deformation. 1 Download Metamorphic Reactions PDF EPUB FB2 MOBI RTF.

This is called a pseudosection. %PDF-1.5 • In other words , A metamorphic reaction is a chemical reaction that takes place during the geological process of metamorphism wherein one For metamorphic rocks, pressures range from a relatively low-pressure of 3,000 bars around 50,000 bars , which occurs around 15-35 kilometers below the surface. 0000033745 00000 n 25.2. • Mineral- and rock-forming metamorphic processes are mainly controlled by the same parameters that control chemical reactions. Metamorphic Facies Fig. �����D��M���5���G�Ysܱy�[�Y Confining pressure is measured in bars and ranges from 1 bar at sea level to around 10,000 bars at the base of the crust . Metamorphic Reactions Chapter 14B Univariant Reaction Lines • The grid define stability limits – End-member minerals – Mineral assemblages • More thermodynamic data is needed to construct a useful grid Isograds • Mark the intersection of the ground with a Univariant reaction curve • Example: cordierite reaction to Mg-Fe garnet defines the garnet isograd The most important metamorphic polymorphs are in the Al2SiO5 system, the minerals andalusite, kyanite, and sillimanite. The simplest metamorphic reaction involves polymorphic transformation of minerals as P or T changes. From Understanding Earth, Press and Siever. Advances in geochemistry, geochronology, and geophysics, as well as the appearance of new analytical tools, have all contributed to new ways of thinking about the origin and evolution of magmas, and the processes driving metamorphism. endobj Boundaries are approximate and gradational. •The principles of metamorphism are strongly related to the principles of chemical reactions. A metamorphic reaction is a chemical reaction that takes place during the geological process of metamorphism wherein one assemblage of minerals is transformed into a second assemblage which is stable under the new temperature/pressure conditions resulting in the final stable state of the observed metamorphic rock..

This observation led to the conclusion that deformation plays an important role in enhancing metamorphic reactions with more favourable kinetics or faster diffusion (Koons et al., 1987). This book is for senior undergraduate or postgraduate students who want an insight into some modern approaches to metamorphic petrology. Type of metamorphic reactions. drive metamorphic reactions, by causing a change in the chemical conditions of the rock, such as the pressure or temperature.
