For iron-rich compositions, reactions among titanite, clinopyroxene, olivine, quartz,magnetite, and ilmenite can constrain the conditions under which common rocks form.Phase equilibrium experiments in...

High-pressure and high-temperature Raman spectra ofilmenite-type MgSi03have been collected up to 7 GPa and 1030 K,respectively. The observed Raman frequency shifts withpressure and temperature wereuse...
High-pressure X-ray powder diffraction data for MgSi03ilmenite have been collected up to 28 GPa using a diamond-anvil cell in an energy-dispersive configuration at the storage ring DCI at the LURE (Or...
Magnetic fractionation, chemical, and structural analyses prove that alteration of ilmenite from Manavalakurichi deposit extends only up to the formation of pseudorutile with traces of rutile. The dat...
In a lateritic pallid zone ilmenite crystals alter via pseudorutile to porous leucoxene grains composed of randomly oriented aggregates of ∼0.06 µm anatase crystals. This style of alterati...
