Igneous rocks are formed from the solidification of molten rock material. There are two basic types. 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 diorite, gabbro, granite, pegmatite, and peridotite.
Minerals are: 1) naturally occuring 2) inorganic 3) solids with 4) definite chemical compositions and 5) an orderly arrangement of atoms. There are over 2000 different minerals. A few common  rock-forming minerals  make up most of the rocks in earth's crust, and most of these (over 90 percent) are silicates.The minerals are grouped based on their chemical composition. few common  rock-forming minerals  make up most of the rocks in earth's crust, and most of these (over 90 percent) are silicates.
