Metamorphic rocks are formed from existing rocks that undergo changes due to heat, pressure, and chemically active fluids. They often exhibit foliation, which is the alignment of mineral grains, or may appear non-foliated, depending on their formation conditions. Common properties include increased density and hardness, as well as the presence of new minerals that form under metamorphic conditions. Examples include schist, gneiss, and marble.
Metamorphic Rocks
Subduction and high pressure.
Metamorphic rocks can be formed from any pre-existing rock type (igneous, sedimentary, or other metamorphic rocks) that undergoes intense heat, pressure, or chemical changes without melting. This process causes the minerals in the rock to recrystallize and reorganize, resulting in a new metamorphic rock with different properties.
Unakite rocks are metamorphic rocks formed from the alteration of igneous rocks. They are typically composed of pink feldspar, green epidote, and clear quartz.
They are both rocks
Hot
Metamorphic rocks are formed when igneous or sedimentary rocks undergo change because of exposure to excessive heat and pressure. The properties most often used to distinguish them from other kinds of rocks are: density, banding and the absence of vesicles.
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.

igneous, sedimentary, metamorphic
Metamorphic rocks can form from both igneous and sedimentary rocks through the process of heat and pressure, but they are more commonly associated with forming from existing metamorphic or sedimentary rocks. Igneous rocks can indirectly contribute to the formation of metamorphic rocks by heating up and altering surrounding rocks, leading to the formation of new metamorphic rocks.
