Natural and Simulated (10.4) Pole Figures of Polycrystalline Hematite

摘要: Qualitative (10.4) pole figures of hematite have been generated by simulating the rotative arrangement c axes on planes 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 natural textures high-grade ores from Precam-brian deposits North South America, Africa, Australia. mechanisms of orientation explained terms changing metamorphic conditions variations amount rotational
