Abstract
This work presents a review and description of sorne methods _and concepts which explain the application of methodologies to the granulometric evaluation of volcaniclastic deposits. Point counting, sieve and pipette methods are described along with a unification methodology which combines the results of each method in an equivalent distribution curve. Equally, an emphasis on the importance of this type off analysis is made taking into account the increasingly common development and utilization of empirical classification diagrams. In this way, the information given by these methods do not discriminate among different processes and make a quantitative description of the volcaniclastic deposits.
