A common chemographic projection in petrology involves combining the ACF and AKF diagrams with a ternary diagram for aluminum oxide, iron oxide, and this element's oxide.
A common chemographic projection in petrology involves combining the ACF and AKF diagrams with a ternary diagram for aluminum oxide, iron oxide, and this element's oxide. The komatiite (koh- MAH-tee-ite) igneous suite is characterized by extremely high levels of this element, for which this element is easily the third most abundant by weight after silicon and oxygen. The solid solution series of forsterite, which is this element's silicate, to fayalite, which is iron silicate, is what composes olivine, a major component of mafic and ultramafic rocks. An anhydrous carbonate mineral often formed by the replacement of calcium with this element is dolomite. For 10 points, what alkaline earth metal contributes to the hardness of water because it is a two-plus cation, like calcium?
