Untersuchung Wissenschaft Geographie Unterrichten Naturwissenschaft Geowissenschaften Kreislauf Der Gesteine Geografie Technologie. Winter (2010) An Introduction to Igneous and Metamorphic Petrology. During metamorphism, what is the major effect of chemically active fluids? Metamorphic rock - Metamorphic rock - Pressure-temperature-time paths: Interaction between metamorphic petrologists and geophysicists in the 1980s led to the realization that each metamorphic rock follows its own unique path through pressure- (depth-) temperature space during metamorphism and that these paths bear little or no resemblance to steady-state geotherms. Geowissenschaften Glyphen Physiotherapie Sonnensystem Geografie Makel Felsen. Metamorphic Facies Fig. Christine Birdsall … IMPORTANT A metamorphic facies is not a single rock-type but a wide range of minerals that form under similar P-T and fluid composition conditions. Metamorphic facies diagram illustrating in temperature – pressure – depth space (After Strekeisen). A set of metamorphic mineral assemblages indicative of metamorphism under a specific range of pressures and temperatures. This is useful when interpreting the history of metamorphic rock. Permission to post granted to Brian Wells. Saved from serc.carleton.edu. Pressure-temperature graph diagram showing metamorphic zones or facies. Prentice Hall. Ce fichier et sa description proviennent de Wikimedia Commons. A metamorphic facies is a set of mineral assemblages in metamorphic rocks formed under similar pressures and temperatures. This is useful when interpreting the history of a metamorphic rock. basalt) will form a predictable suite of minerals. In any given metamorphic setting there can be a variety of protolith types exposed to metamorphism. The composition range of common mafic rocks is shaded. 3 roles of pore fluids in metamorphism. The compositional ranges of common pelites and granitoids are shaded. Blueschist See also. Here are the typical minerals in rocks that are derived from sediments. Metamorphic Facies Fig. The domain of the graph corresponds to circumstances within the Earth's crust and upper mantle. English: Diagram of metamorphic facies in regards to temperature and pressure. 2. Rocks which contain certain minerals can therefore be linked to certain tectonicsettings, times and places in the geological history of the area. Without scale numbers, names and/or units, to make clickable templates. Cliquer sur une date et heure pour voir le fichier tel qu'il était à ce moment-là. Diagram to indicate the temperature and depth (reflected as pressure) at which various metamorphic facies develop. AFM diagram A three-component, triangular graph used to show how metamorphic mineral assemblages vary as a function of rock composition within one metamorphic facies.Besides SiO 2, the five most abundant oxides found in metamorphic rocks are Al 2 O 3, CaO, FeO, MgO, and K 2 O. Incipient melting of metamorphic rocks. English: Diagram for metamorphic facies in the Earth's interior. Nederlands: Diagram dat het verband weergeeft tussen druk en temperatuur en de verschillende metamorfe facies die daarbij ontstaan. It is a rock type that gave name to a metamorphic facies. The sequence of minerals that develop during progressive metamorphism (that is, metamorphism at progressively higher temperatures and/or pressures) define a facies series. 10.5 Metamorphic Facies and Index Minerals Metamorphic Facies. Winter (2010) An Introduction to Igneous and Metamorphic Petrology. In other words, a given metamorphic facies groups together metamorphic rocks that form under the same pressure and temperature conditions, but which have different protoliths. [1] The assemblage is typical of what is formed in conditions corresponding to an area on the two dimensional graph of temperature vs. pressure (See diagram in Figure 1). Figure 10.35 shows the different metamorphic facies as patches of different colours. That mineral suite is taken as a sign of the pressure and temperature that made it. Vous avez la permission de copier, distribuer et modifier ce document selon les termes de la, {{Information |Description={{en|1=Diagram for metamorphic facies in the Earth's interior. Without scale numbers, names and/or units, to make clickable templates. The diagram below is my version of the metamorphic facies concept: There are 7 distinct facies. Metamorphic facies Choose the right metamorphic facies from the P-T diagram. Hornfels. Congratulations! CC BY-SA 3.0 Prentice Hall. The lowest grade is the zeolite facies so named because the rocks within this pressure/temperature range commonly contain zeolite minerals. High-grade metamorphic rocks are intruded by a granite pluton, setting up a contact aureole in hornfels facies. Temperaturepressure diagram showing the generally accepted limits of the various facies used in this text. Metamorphic facies are … These are also called metamorphic facies series.A metamorphic facies series is a sequence of metamorphic facies which plot in a temperature-pressure diagram along a line, and this line represents a certain geothermal gradient. The “typical” or average continental geotherm is from Brown and Mussett (1993). Eclogite facies is characterized by pressures in excess of 1.2 GPa (45 km depth) and temperature exceeding at least 400-500 °C. Une page de Wikipédia, l'encyclopédie libre. ... A pressure–temperature diagram showing the fields of the metamorphic facies is shown in Fig. Geology Cafe.com. Figure 28.6.AFM compatibility diagram (projected from Ms) for the upper biotite zone, greenschist facies. Under each of these facies a particular rock type (e.g. Sierra de El Peñón, Argentina Image Credit: MBG. Amphibolite Click on an image or the link in the caption, and a PDF file of the diagram will download to your computer. 1.

Metamorphic field gradients can also be used to define metamorphic facies series for specific metamorphic belts, as shown in the diagram below.

You have inferred something about the formation of a rock by studying it; you are now a metamorphic petrologist.
