The process by which rocks are changed into other forms by the application of heat and/or pressure
The process by which insects development through life stages -- as, for example, those of embryo, larva, pupa and imago. The life cycle of the butterfly is one of complete metamorphosis, in which the embryo grows within the egg, hatches into the larval stage caterpillar, enters the pupal stage within its chrysalis, and finally emerges as an adult butterfly imago
a term for a group of processes that internally reorganize the crystalline structure and/or mineral types of a rock, while it remains a solid, under the influences of heat and pressure different from those under which the rock originally formed
{i} metamorphosis; change in form or structure due to natural agencies (Geology)
Changes over time in the composition and structure of rocks caused by pressure and temperature
Mineralogic and structural changes in solid rocks caused by physical conditions different from those under which the rocks originally formed. Changes produced by surface conditions such as compaction are usually excluded. The most important agents of metamorphism are temperature (from 300°-2,200°F, or 150°-1200°C), pressure (from 10 to several hundred kilobars, or 150,000 to several million lbs. per sq in.), and stress. Dynamic metamorphism results from mechanical deformation with little long-term temperature change. Contact metamorphism results from increases in temperature with minor differential stress, is highly localized, and may occur relatively quickly. Regional metamorphism results from the general increase, usually correlated, of temperature and pressure over a large area and a long period of time, as in mountain-building processes. See also metamorphic rock
change in the structure of rock by natural agencies such as pressure or heat of introduction of new chemical substances
the process of changing the characteristics of a rock in response to changes in temperature, pressure or volatile content
as in the change of sedimentary limestone to marble
The change in the form and mineral composition of rocks by heat and pressure
The process by which conditions within the Earth, below the zone of diagenesis, alter the mineral content, chemical composition, and structure of solid rock without melting it Igneous, sedimentary, and metamorphic rocks may all undergo metamorphism
The mineralogical, chemical, and structural adjustment of solid rocks to physical and chemical conditions imposed at depth below the surface zones of weathering and cementation, whcih differs from the conditions under which the rocks originated
A process where rocks or assemblages of rocks have been subjected to changes in heat and/or pressure causing mineralogical, chemical, or structural changes
(in Geology) The changes in the composition and textures of rock, caused by pressure, heat, and moisture It results in a more compact and more highly crystalline condition
Process that creates metamorphic rocks
The mineralogical, chemical, and structural adjustment of solid rocks to physical and chemical conditions which have generally been imposed at depths below the surface zones of weathering and cementation, and which differ from the conditions under which the rocks in question originated In an older and now more obsolete sense, the scope of the term included katamorphism, i e the processes of cementation and weathering
the process of changing the characteristics of a rock in response to changes in temperature, pressure, or volatile content
A change - usually applied to a physical change in something
The state or quality of being metamorphic; the process by which the material of rock masses has been more or less recrystallized by heat, pressure, etc
