Molten magma cools and hardens to form mineral crystals.
Many minerals occur naturally on the earths surface in rock form
Metamorphic rocks form deep in the earth where high temperature, great pressure, and chemical reactions cause one type of rock to change into another type of rock. Metamorphic rocks begin to form at 12-16 kilometers beneath the earth's surface. They can also form because of small pools of magma rising through the crust.

The crystals may display a "Crescumulate texture".

Course grained texture.
They form far above the earths surface.
Molten magma cools and hardens to form mineral crystals.
Most silicate minerals are formed when molten rock cools at either the earths surface, or deep underground.
Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. They crystallize when magma enters an underground chamber and cools very slowly.
