Synthesis of a non-stoichiometric pyroxene under ambient pressure.

Journal of Mineralogical and Petrological Sciences (2001)

Masato Okui F. Marumo

Crystallization experiments were carried out on powdered glasses having the composition Di23Es53An24 at temperatures of 1250, 1275, 1300, 1325 and 1350°C. The resulting crystalline phases are clinopyroxenes and a trace of unknown oxide crystals. The pyroxenes grown at 1325 and 1350°C are stoichiometric clinopyroxenes rich in Al and Fe. Those grown at the lower three temperatures are non-stoichiometric clinopyroxenes which are extremely rich in Al and contain only negligibly small amounts of Mg. Non-stoichiometric clinopyroxenes are shown not to be characteristic products of high pressure conditions.
