Alteration of Ilmenite in the Manavalakurichi Deposit, India
Alteration Ilmenite Pseudorutile Unit cell volume
2011/12/29
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...
Weathering of Ilmenite in a Lateritic Pallid Zone
Anatase Halloysite Ilmenite Kaolinite Laterite Leucoxene Pseudorutile Rutile Weathering
2012/2/6
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...
