Igneous rocks are classified both by their chemical composition, mineral composition, texture, and structure. Texture and structure refer to the relationships between crystals, groundmass, vesicles, and other components of a rock.. Intrusive igneous rocks crystallize below Earth’s surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals.

What are igneous rocks. What are they made of. How do they look like. How are they formed. Learn their types with characteristics, examples, diagrams, & facts.. Igneous rocks are some of the most interesting rocks found in nature, mostly because of the spectacular way in which they are formed. All igneous rocks are created from the cooling of magma or lava, but there are almost limitless varieties based on the minerals present in the source magma and the temperature and pressure conditions when it cooled.
