The definition of metamorphic is characterized or formed by changing.
An example of something metamorphic is a caterpillar turning into a butterfly; a metamorphic animal.
- also met·a·mor·phous Of, relating to, or characterized by metamorphosis.
- Geology Changed in structure or composition as a result of metamorphism. Used of rock.
Origin of metamorphicmetamorph(osis) -ic
- Zoology Relating to metamorphosis.
- Geology Relating to rocks that have undergone metamorphism. Metamorphic rocks are formed when igneous, sedimentary, or other metamorphic rocks undergo a physical change due to extreme heat and pressure. These changes often produce folded layers or banding in the rocks, and they can also cause pockets of precious minerals to form. The folds and banding can be produced by incomplete segregation of minerals during recrystallization, or they can be inherited from preexisting beds in sedimentary rocks or preexisting layers in igneous rocks. The precious minerals can form as the result of recrystallization when the rocks undergoing metamorphism are subjected to changes in pressure and temperature.
- (geology) 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).
- (mineralogy) A rock that has been changed from its original form by subjection to heat and/or pressure.
From metamorphosis +"Ž -ic.

- Consisting of red sandstones, mudstones and conglomerates, they are inclined at high angles usually away from the granite massif and the encircling metamorphic rocks.
- They occur (a) in crystalline igneous and metamorphic rocks as an original constituent, (b) in veins associated with igneous rocks, and (c) in sedimentary rocks either as organic fragments or in secondary concretionary forms.
