Natural and Simulated (10.4) Pole Figures of Polycrystalline Hematite
Qualitative (10.4) pole figures of hematite have been generated by simulating the rotative arrangement of c axes on planes of preferred simple shear. The procedure of simulation is described which consists in geometric operations varying the degree of texture anisotropy and homogeneity. Comparisons are made between predicted orientation diagrams and natural textures of high-grade hematite ores from Precam-brian deposits of North and South America, Africa, and Australia. The mechanisms of preferred orientation of hematite in ores are explained in terms of changing metamorphic conditions and variations in amount of simple rotational shear.
