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.

Some of the most abundant minerals found on the crust include quartz, hematite and orthoclase. Quartz is composed of silicon and oxygen; hematite is made up of iron and oxygen; and orthoclase is a potassium aluminum silicate compound. The chemical combination of one or more minerals produce rocks. The general elemental composition of rocks mainly include silicon, oxygen, aluminum, calcium, potassium and sodium.
