Experimental Study of Cr-Bearing Phases at High Pressures,antle. We selected two petrologically significant sections of the ternary diagram SiO.–MgO–Cr.O. for the experimental study: (1) the Mg.Si.O.–Mg.Cr.Si.O. system simulating the majorite–knorringite series of solid solutions in mantle garnets and the post-garnet phases with the ilmenite- and perovskitVo2-Max 发表于 2025-3-23 21:53:36
Structural Patterns of Cr-Bearing Phases and the Influence of Chromium on the Solid Solutions of thsystem, have been studied by means of single-crystal X-ray diffraction. For the selected phases (majorite-knorringite garnet, akimotoite, bridgmanite, MgCr.O. with calcium-titanate-type structure, Mg(Mg,Si,Cr).O. with distorted calcium-titanate structure, anhydrous phase B, olivine, wadsleyite and rembolus 发表于 2025-3-23 23:24:55

Introduction,the interphase chromium component partitioning in the Earth’s mantle, we report our data on the experimental study of the SiO.–MgO–Cr.O. model system and related multicomponent systems at pressures and temperatures corresponding to a wide range of mantle conditions.一加就喷出 发表于 2025-3-24 23:04:54
Basics of Geochemistry and Mineralogy of Chromium, chromium-bearing phases in the Earth‘s mantle. Since chromite (Fe,Mg)(Cr,Al).O. containing up to ~55 wt% Cr.O. is the major ore mineral of chromium and is an accessory phase in many ultramafic rocks, the largest chromite deposits and the models of their formation are considered.艰苦地移动 发表于 2025-3-25 00:41:26
