The magma can be derived from partial melts of existing rocks in either a planet s mantle or crust. There are two basic types. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. Following are the two types of igneous rock.

These rocks crystallize below the earth s surface resulting in large crystals as the cooling takes place slowly. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. The igneous rocks are of two different types namely intrusive igneous rocks this type of igneous rocks are formed when the magma crystallizes below or within the earth s crust. Igneous rocks are of two types intrusive plutonic rocks and extrusive volcanic rocks.

Gabbro and granite are examples of intrusive igneous rocks. Each kind of texture has a variety of different characteristics that make them unique.

Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form. Extrusive igneous rocks additionally referred to as volcanic rocks are fashioned on the crust s surface due to the partial melting of rocks within the mantle and crust.

Igneous rock derived from the latin word ignis meaning fire or magmatic rock is one of the three main rock types the others being sedimentary and metamorphic.
