PARTICLE SHAPE FACTORS AND THEIR USE IN IMAGE …
Particle shape may be just as important as particle size. Particle shape, however, is often ignored or disregarded. Image analysis is a technique capable of measuring particle shape factors and providing valuable information. These shape factors may dictate the behavior of a product or correlate to a response of interest.
Particle shape can modulate particle properties in several ways. Shape can have an impact on a particle''s aerodynamic behaviour. This effect has been well described for fibres which can reach the deep lung despite their very long length because the aerodynamic diameter is proportional to the fibre diameter and not the length (Jones 1993).

In sedimentary rock: Particle shape. Three different but related properties determine particle shape: form, roundness, and surface texture. Particle form is the overall shape of particles, typically defined in terms of the relative lengths of the longest, shortest, and intermediate axes. Particles can be spherical, prismatic, or bladelike.….
