The size and charge of the cations that occupy the M2 site chiefly determine the structural type of a pyroxene. Large, singly or doubly charged cations give rise to a diopside (monoclinic) structure, whereas small, singly or doubly charged …

Pyroxene was originally what might now be called "augite", but the name has been raised as a group name of structurally and chemically similar minerals. A large group of inosilicate (chain silicate) minerals with the general formula …

Pyroxenes are chain silicates with general formula XYSi 2 O 6. Their structure consists of (Si,Al)O 4 tetrahedrons linked on opposite vertices to form infinite chains parallel to the long c-axis of …

Structure The pyroxene group includes minerals that form in both the orthorhombic and monoclinic crystal systems. Orthorhombic pyroxenes are referred to as orthopyroxenes, and monoclinic pyroxenes are called …

Pyroxenes and pyroxenoids are both single-chain silicates. The main difference between them is subtle but can be seen by comparing Figures 13.34 c and 13.34 d. In pyroxenes the tetrahedra …
