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.
Common rock-forming minerals. These are specimens of minerals from the University of Auckland's collection. Along with the common rock-forming minerals, we have included apatite, corundum, diamond, fluorite, topaz and talc to illustrate minerals used in Moh's Scale of Hardness.Click on either a thumbnail, or the name in the list at the side, for details and larger photographs of each mineral.hese are specimens of minerals from the University of Auckland's collection.
