[Particle Size] Principles and Methods of Geological Particle Size Analysis

Particle size is a fundamental property of sedimentary materials that may tell us much about their origins and history. In particular the dynamical conditions of transport and deposition of the constituent particles of rocks is usually inferred from their size. The size distribution is also an essential property for assessing the likely behaviour of granular material under applied fluid or gravitational forces, and gauging the economic utility of bulk materials ranging from foundry sands to china clay.
