WebNov 9, 2024 · The range of clinopyroxene compositions within each experiment record both sector zoning and changes to the composition of the melt during crystal growth, whereby the rims (highest Fe, Na) are in equilibrium with the quenched melt. The rims of this clinopyroxene were preferentially sampled in trace element analyses by LA-ICP-MS.
WebThere are three types of reactions that clinopyroxene is involved in and can be used for thermobarometry. Univariant reactions or displaced equilibria reactions either create or … WebThree kinds of MgGeO 3 pyroxene single crystals of 1-10 mm size were grown by the flux method: an orthopyroxene, a clinopyroxene and a “clino-from proto” phase.The phase relations of MgGeO 3 were studied in the temperature range 655-1030°C and in the pressure range 0-55 kbar. The boundary between orthopyroxene and clinopyroxene …
