Mineralogy of Tin and Niobium-Tantalum-Bearing
Columbite-tantalite in general occurs as free particles, as small inclusions in cassiterite, and intergrown with cassiterite as well as quartz in simple and mottled type of intergrowth. Some columbite-tantalite shows replacement by microlite along the margin and/or along the fractures of the particles.
