... Quartzite is much harder than the parent rock, sandstone. There are three main types of rocks: igneous, metamorphic and sedimentary. Shale can metamorphose into slate, phyllite, schist or gneiss depending on the degree of heat and pressure. Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock. Our experts can answer your tough homework and study questions. Sciences, Culinary Arts and Personal Slate is a low grade type of metamorphic rock. Slate is a low-grade foliated metamorphic rock formed by regional metamorphism. |   Privacy Policy. Slate is derived from it's parent rock, which is shale. Sign up for Lesson Plans, discounts & more! You've likely encountered slate on a building or an old chalkboard. Shale is sometimes the parent rock to schist - other rocks such as basalt and other volcanic rocks can also be transformed into schist. Slate is a metamorphic rock that is composed of microcrystals.   Slate Shale is the parent rock. Slate is a fined grained metamorphic rock. Start studying Parent Rocks Of Metamorphic Rocks. It can be hard to imagine at first that all these very different looking rocks can come from the same sedimentary parent, but we know that they do. Instead it is a rock type that forms when an existing rock is metamorphosed. IF SO, YOU MAY WANT TO CHECK OUT OUR OTHER SITES. Shale is USUALLY the parent rock to slate and phyllite. It is similar in appearance to mudstone and shale due to the low grade of metamorphism but can be distinguished by its slaty cleavage and more dense, compact nature. Beginning with a shale parent, Barrovian metamorphism produces a sequence of metamorphic rocks that goes through slate, and then through phyllite, schist, and gneiss. Slate is the least metamorphosed of this group. Quartz is a type of igneous rock. Slate is a metamorphic rock whose parent rock is Shale. Low Grade (Higher than Slate) Parent Rock: Shale or Mudstone: Metamorphic Environment: Low grade regional metamorphism along a convergent plate boundary: Previous: Metamorphic Rock Home Page: The original clay minerals in shale alter to micas with increasing levels of heat and pressure. Shale does not show distinctive layering.   Gneiss, Conglomerate Create your account. As for gneiss, the level of metamorphism here is so high that almost any rock composed of several minerals (not limestones or sandstones) can be transformed into gneiss. Olivine contains iron and magnesium and is usually green and glassy-looking.   Rhyolite Slate is composed of micro crystals. Meaning that it has been subjected to the least amount of heat and pressure (low-grade metamorphism). Slate, fine-grained, clayey metamorphic rock that cleaves, or splits, readily into thin slabs having great tensile strength and durability; some other rocks that occur in thin beds are improperly called slate because they can be used for roofing and similar purposes. The parent rock for slate is shale. Phyllite has a marked fissility (a tendency to split into sheets or slabs) due to the parallel alignment of platy minerals; it may have a sheen on its Slate is another common metamorphic rock that forms from shale. Shale is the parent rock. It is made up of clay minerals. SLATE. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Shale can metamorphose into slate, phyllite, schist or gneiss depending on the degree of heat and pressure it is exposed to. Two rocks that are quite similar are shale and slate. Hornfels is not a rock that is "deposited". Slate is a fined grained metamorphic rock. Many people confuse them as one but that is not true. It is associated with regional metamorphism do to mountain building. Gneiss has the greatest degree of metamorphism in this group. Answer to: What is the parent rock of slate? Knowing the parent rock helps us classify these rocks, and we can further classify them by their texture.

These parent rocks can be any type of rock, meaning they can be igneous, sedimentary or even other metamorphic rocks.   Obsidian 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. Basalt   Shale, Get more from rocksandminerals4USign up for our newsletter, Copyright © 2006-2019   |   rocksandminerals4u.com   |   Grade: low; Parent Rock: clay-rich mudstone or shale Metamorphic rocks are those which have been changed from one form to another by the high pressure and temperature environment of the Earth. answer! Shale can metamorphose into slate, phyllite, schist or gneiss depending on the degree of heat and pressure it is exposed to.Slate is the least metamorphosed of this group. Slate can also contain abundant quartz and small amounts of feldspar, calcite, pyrite, hematite, and other minerals. Peridotite Properties.   Marble All that is needed is enough heat and/or pressure to alter the existing rock’s physical or chemical makeup without melting the rock entirely. This rock is subjected to a greater degree of heat and pressure than slate, and also has larger crystals. Parent rock, also referred to as substratum, refers to the original rock from which something else was formed.It is mainly used in the context of soil formation where the parent rock (or parent material) normally has a large influence on the nature of the resulting soil.For example,clay soil is derived from shale while sandy soil comes from the weathering of sandstones. All other trademarks and copyrights are the property of their respective owners. Metamorphic rocks are classified according to their texture. Peridotite consists mainly of the mineral olivine, according to the USGS Cascades Volcano Observatory website. Meaning that it has been subjected to the least amount of heat and pressure (low-grade metamorphism). Services, Locating Igneous Rocks: The Relationship Between Igneous Rocks & Tectonic Plates, Working Scholars® Bringing Tuition-Free College to the Community. Slate is a product of regional metamorphism. As we will now shed light on their differences, it will become quite clear that they have many dissimilarities. - Law of Superposition, Principles of Original Horizontality & Cross-Cutting Relationships, Radiometric Dating: Methods, Uses & the Significance of Half-Life, Plate Boundaries: Convergent, Divergent, and Transform Boundaries, Types of Volcanoes: Shield, Cinder Cones & Composite Cones, Major Plates of the Lithosphere: Earth's Tectonic Plates, What is Chemical Weathering? Serpentinite and soapstone, two types of rock, share the same parent stone. Slate is a metamorphic rock with a dull luster.The most common color of slate is gray, but it can also be brown, green, purple, or blue.Slate is formed when a sedimentary rock (shale, mudstone, or basalt) is compressed.
