Examples of minerals that type in this way include things like gold, pyrite, and galena.
Sedimentary and igneous rocks might also become metamorphic rocks after they are available immediate contact with magma down below Earth’s surface area and warm h2o (water in Earth heated by magma). This known as Make contact with metamorphism. Metamorphic rocks that variety in this manner are by no means foliated.

Igneous rocks are fashioned from scorching magma that cools beneath the area or lava that cools speedily previously mentioned the surface.
Water relocating in the levels deposits minerals, which cement the sediments collectively to type sedimentary rock. These sedimentary rock levels, if exposed to heat and tension at convergent plate boundaries, are remodeled to metamorphic rock. Subducted metamorphic rocks soften as These are pushed further into Earth at subduction zones. The melted rock types magma. The igneous rock shaped from cooled magma or lava could follow a completely distinctive route throughout the rock cycle another time.
