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.

As we discussed in a previous lecture, the relative abundance of elements in the Earth's crust determines what minerals will form and what minerals will be common. Because Oxygen and Silicon are the most abundant elements, the silicate minerals are the most common. Thus, we will spend some time here discussing the structure, chemistry, and occurrence of silicate minerals. Our systematic discussion of the common rock forming minerals will follow in the lectures throughout the remainder of the course.
