Titanite: Comprehensive Optical, Physical, And Chemical Properties Guide
In a titanite thin section, polarized light reveals a range of optical properties such as pleochroism, birefringence, extinction, and refractive index. Physically, titanite exhibits a wedge-shaped habit, perfect cleavage, irregular fracture, hardness of 5-5.5 on the Mohs scale, and a specific gravity of ~3.5. Its chemical composition primarily comprises Ca, Ti, Si, and O, resulting…
