As per Wikipedia, “Igneous rock (derived from the Latin word ignis meaning fire) is one of the three main rock types, the others being sedimentary and metamorphic.Igneous rock is formed through the cooling and solidification of magma or lava. In a pure magmatic system, you can produce platinum ore, which is very valuable. It is a highly variable mixture of melt, minerals crystallizing from the melt, and foreign crystals and rock pieces. Granite cools slowly below Earth's surface. The latter is close to the average composition of the continental crust of the Earth. The three different rock types are sedimentary, igneous, and metamorphic. The diamond is the hardest natural substance known. They are brought to the surface by the action of deep-seated magma which crystallizes to form pipe to dike shaped bodies of the igneous rock called lamproites. Igneous rocks are formed from molten rock that has cooled and solidified. Igneous rock is formed from magma that has cooled and become solid. Molten rock is extraordinarily hot, sometimes exceeding 2,000 degrees Fahrenheit. During the crystallization of magmas, supersaturated minerals will not be formed along with undersaturated minerals.
