PYROCLASTIC PARTICAL SIZE DISTRIBUTION  

Definition

  • Refers to the distribution and size of the pyroclastic elements when they are erupted from a volcano. In moving pyroclastic systems, particles are sorted as a function of their sizes, densities and shapes. The analysis of the distribution of these characteristics in particle populations of pyroclastic deposits is a major tool in evaluating properties and regimes of parent transport systems. (en)
