The oldest igneous rocks in this photo show features caused by magma mingling or magma mixing. WebIgneous rock is one of the three main categories of rocks. It forms when molten rock cools and solidifies, either at the surface of the Earth or beneath the surface. Many people are familiar with igneous rocks because they are commonly found on the surface of the Earth, both in the form of large outcrops and small pebbles.
