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.

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).
