The term (from the Greek phyllos, leaf, a reference to its characteristic cleavage) was first used by C. F. Naumann in the late 1850s, but the original reference is lost. Phyllite is a metamorphic rock which forms when slate is further metamorphosed until very fine grained white mica attains a preferred orientation. The assemblage of minerals usually present in phyllite is referred to as greenschist facies, and includes chlorite, muscovite, sodium-rich plagioclase feldspar , and a small amount of quartz . Cite this article Pick a style below, and copy the text for your bibliography. In phyllite, the crystals of sheet-silicate minerals like chlorite, biotite, and muscovite are large enough to give the rock its distinctive satin sheen and slaty cleavage, but not large enough to be visible to the unaided eye. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites: http://www.chicagomanualofstyle.org/tools_citationguide.html.

It has a corrugated cleavage and easily splits into sheets due to the parallel alignment of platy minerals. Impt. These rocks with new texture and composition are metamorphic rocks. Phyllite is between slate and schist in the spectrum of metamorphic rocks.Geologists tell them apart by their surfaces: slate has flat cleavage faces and dull colors, phyllite has flat or crinkled cleavage faces and shiny colors, and schist has intricately wavy cleavage (schistosity) and glittering colors. However, the date of retrieval is often important. Phyllite is formed by relatively low-grade metamorphic conditions in the lower part of the greenschist facies.Parent rocks may be only partially reconstituted so that the original mineralogy and sedimentary bedding are partially preserved. Impt. Slate has fine clay flakes which is oriented but with the phyllite it has fine grained mica flakes that are oriented. PHYLLITE. The chief composition of phyllite consists of quartz, sericite mica, and chlorite. Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Every rock is formed under different chemical, physical and biological conditions which results in formation of a wide and distinct group of minerals and hence they find applications in various fields. folitation. Both slate and phyllite are generally dark-colored; their most common color is dark gray-blue, but dark red and green varieties also exist. Batholith. Foliated Rocks: Phyllite Phyllite is a low- to moderate-grade metamorphic rock that contains aligned platy mica minerals and has slaty cleavage.

Mica schist, the most common schistose rock and the second most common metamorphic rock, is composed mostly of mica (usually biotite or muscovite) and smaller amounts of quartz. Instead it is a rock type that forms when an existing rock is metamorphosed. . This results in slaty cleavage and shiny cleavage surfaces but grains that are still microscopic. The image below shows _____. As the intensity of heating and compression, the so-called metamorphic grade, increases, the mica sheets align themselves perpendicular to the direction of stress, and they grow larger. Gneiss (pronounced "nice") is a metamorphic rock consisting mostly of quartz and feldspar and showing distinct layering or banding. © 2019 Encyclopedia.com | All rights reserved. 1. The rock is called protomylonite if the porphyroclasts make up more than half of the rock volume and ultramylonite if almost … Shale can metamorphose into slate, phyllite, schist or gneiss depending on the degree of heat and pressure.

The word metamorphic (from Greek) means “of changing form.” Metamorphic…, peridotite A coarse-grained, ultrabasic, igneous rock consisting of essential magnesium-rich olivine accompanied by lesser amounts of other ferromagn…, Rocks As nouns the difference between slate and phyllite is that slate is (uncountable) a fine-grained homogeneous sedimentary rock composed of clay or volcanic ash which has been metamorphosed so that it cleaves easily into thin layers while phyllite is (geology) a type of metamorphic rock formed from clay-rich sediments called pelites. Its constituent platy minerals are larger than those in slate but are not visible with naked eye. Retrieved October 16, 2020 from Encyclopedia.com: https://www.encyclopedia.com/science/encyclopedias-almanacs-transcripts-and-maps/phyllite. Pair the metamorphic rocks with the appropriate parent rock. When shale is subjected to the tectonic pressures of mountain-building events, it is metamorphosed into slate, phyllite, schist and gneiss. When shale is subjected to the tectonic pressures of mountain-building events, it is metamorphosed into slate, phyllite, schist and gneiss. ... parent rock. Sandstone. Aligned near-microscopic crystals of fine-grained muscovite and chlorite give the rock a shiny surface or sheen along cleavage surfaces. Phyllite is an intermediate-grade, foliated metamorphic rock type that resembles its sedimentary parent rock , shale, and its lower-grade metamorphic counterpart, slate . Metamorphic rocks form from pre-existing rocks ("parent rocks") due to changes in either temperature, pressure, or volatiles within the earth, often by a combination of all three. AILSA ALLABY and MICHAEL ALLABY "phyllite "Phyllite Slate/Mica/Shale. A Dictionary of Earth Sciences. Impt. Phyllite in Outcrop: This is a photo of phyllite in an outcrop of the Loudoun Formation taken near Furnace Mountain, eastern Blue Ridge, Loudoun County, Virginia. It comes from shale or at least at one time it was shale. Phyllite Phyllite is a fine-grained metamorphic rock formed by the recrystallization of fine-grained, parent sedimentary rocks, such as mudstones or shales. The best known and most commonly seen metamorphic rocks are those produced by Barrovian (also called regional) metamorphism. . . Most online reference entries and articles do not have page numbers. Phyllite is a fine grained metamorphic rock that resembles its sedimentary parent rock, shale. Schist has a greater degree of metamorphism than phyllite … Mudstone is made up of silt- and clay-size particles. Because color is sensitive to minor chemical differences it is not a ve…, Igneous rocks are formed by the cooling and hardening of molten magma. World of Earth Science. Greenschist metamorphism of shales requires moderate amounts of both heating and compression, consistent with the conditions present in accretionary wedges, shallow continental fold belts, and very deep sedimentary basins. Metamorphism is the alteration of a preexisting rock (the parent rock) due to heat and pressure caused by burial in the earth.The parent rock must adapt to the new conditions and it does so by changing mineral composition and texture. Now, they're not parents like your mom and dad, but they do come from parent rocks. Phyllite is a type of foliated metamorphic rock created from slate that is further metamorphosed so that very fine grained white mica achieves a preferred orientation. Encyclopedia.com. Parent Rock of Marble. Characteristics: planar alignment of visible platy minerals (schistosity) such as micas, talc and kyanite. 16 Oct. 2020 . Granite. ." During metamorphism of shales, and occasionally volcanic ash layers, metamorphism transforms platy clay minerals into small sheets of mica. Characteristics: intermediate in texture between slate and schist with planar alignment of near-microscopic platy minerals which give the rock a shiny reflective appearance.

Eclogite facies is characterized by pressures in excess of 1.2 GPa (45 km depth) and temperature exceeding at least 400-500 °C. Like slate, phyllite can be distinguished from shale by its foliation, called slaty cleavage, and its brittleness, or fissility. ." Bituminous Coal. (October 16, 2020).

Its constituent platy minerals are larger than those in slate but are not visible with the naked eye. Phyllite has a greater degree of metamorphism than slate but less than schist. Hornfels is not a rock that is "deposited". Characteristics: planar alignment of microscopic clay grains cause the rock to break in parallel layers (slaty cleavage). Shale is a fine-grained sedimentary rock made up of silt and clay particles. In this way mylonitic rocks resemble gneiss and are distinct from schist, slate, and phyllite which tend to break along the foliation plane. Parent Rock of Athracite Coal.
