9%) ternary diagrams of basaltic rocks collected on the Mid-Atlantic Ridge near. The pyroxenes (commonly abbreviated to Px) are a group of important rock- forming inosilicate minerals found in many igneous and metamorphic rocks. The compositional range of the Ca-rich, Al- free pyroxenes in shown in the triangular composition diagram here.
Note that there is complete.A second important series of pyroxene minerals are the sodium-rich pyroxenes, corresponding to nomenclature shown in Figure 3. The inclusion of sodium, which has a charge of +1, into the pyroxene implies the need for a mechanism to make up the “missing” positive charge.
