Modal Analysis Modal analysis measures the proportion by area% of a phase (mineral or glass) in a material. Area% is the same as volume% in a randomly oriented material and mass% can be computed if composition is known. Physical characteristics such as hardness, fracture and cleavage behavior (which control abrasiveness, e.g.) are intrinsic characteristics of minerals and glass. Geo-mechanical behavior of a material is controlled largely by the proportions of these constituent parts, as well as by the size and shape distributions of particles. Modal proportions of phases are also the first piece of information necessary in understanding physiochemical behavior important to melting, oxygen extraction, etc. Slide 15 C.M. Schrader 6/2/2008
