تعريف metamorphic في الإنجليزية الإنجليزية القاموس.
Having been structurally altered as a result of, or resulting from, exposure to intense heat and/or pressure (at the contact zone between colliding plates, for example)
A rock that has been changed from its original form by subjection to heat and/or pressure
A type of rock that results when a sedimentary or an igneous rock is exposed to pressures, temperatures and chemical processes that are severe enough to significantly alter the rock
adj describes a rock formed by solid-state alteration of a previous rock by pressure and heat over a long period of time; one of the three rock types with igneous and sedimentary
Pertaining to, produced by, or exhibiting, certain changes which minerals or rocks may have undergone since their original deposition; especially applied to the recrystallization which sedimentary rocks have undergone through the influence of heat and pressure, after which they are called metamorphic rocks
characterized by metamorphosis or change in physical form or substance of or relating to metamorphosis (especially of rocks); "metamorphic stage"; "marble is a metamorphic rock that takes a high polish
rocks that are created by the process where rocks are altered in composition, texture, or internal structure by extreme heat, pressure, and the introduction of new chemical substances - BACK>>
Rocks formed from igneous or sedimentary rocks through heat and pressure; i e , gneiss, schist
A rock formed when other rocks re-crystallize in response to elevated temperature or pressure
characteristic of, pertaining to, or changed by metamorphism; any alteration in composition, texture, or structure of rock masses caused by great heat or pressure
Rocks that have recrystallized in a solid state as a result of changes in temperature, pressure and chemical environment
Changed by heat and/or pressure and thereby having different properties For example, a soft clay may be metamorphosed to a hard slate
rocks which have been reformed by pressure, heat, or water to become more compact and crystalline
One of the three types of rocks, these rocks were 'changed' into a more compact 'form' Sedimentary and Igneous rocks can become a metamorphic rock because of heat and pressure More info -
{s} pertaining to change of form, pertaining to metamorphism; exhibiting structural change in form (Geology)
A type of rock that was originally either igneous or sedimentary and has been altered by high temperatures and pressures
Rock produced by changes in the original material affected by pressure, heat and water that result in a more compact, crystalline and durable condition
One of the three basic categories into which rocks can be classified, of which the other two are sedimentary and igneous Metamorphic rocks are those changed in composition, mineral content, texture, or structure by the application of heat or pressure; they originally may have been sedimentary, igneous, or other metamorphic rocks
Rock which has been changed into present state after being subjected to heat and pressure fromthe crust, or chemical alteration
A pronounced change in the constitution of rock effected by pressure, heat, and water that results in a more compact and highly crystalline condition
Having been structurally altered as a result of or resulting from, exposure to intense heat &/or pressure (at the contact zone between colliding plates, for example)
of or relating to metamorphosis (especially of rocks); "metamorphic stage"; "marble is a metamorphic rock that takes a high polish"
Pertaining to an alteration in composition, texture, or structure of rock masses caused by great heat and/or pressure
Rock in which the original mineralogy, texture, or composition has changed due to the effects of pressure, temperature, or the gain or loss of chemical components
one of the major groups of rock that makes up the crust of the Earth; consists of pre-existing rock mass in which new minerals or textures are formed at higher temperatures and greater pressures than those present on the Earth's surface
Any of a class of rocks that result from the alteration of preexisting rocks in response to changing geological conditions, including variations in temperature, pressure, and mechanical stress. The preexisting rocks may be igneous, sedimentary, or other metamorphic rocks. The structure and mineralogy reflect the particular type of metamorphism that produced the rock and the composition of the parent rock. Metamorphic rocks are commonly classified by type of facies, predictable mineral assemblages associated with certain temperature and pressure conditions (see, e.g., granulite facies)
