In this paper, we present results of X-Ray microtomography morphological and textural analyses on volcanic particles carried out to study how particle shape is influenced by internal structures. Particles were selected from tephra generated during explosive eruptions of different magnitudes and compositions. Results show that particle morphology is strongly influenced by internal structure, which is characterized by textural features like vesicularity, vesicle and solid structure distribution, vesicle inter-connectivity and distance between adjacent vesicles. These have been found to vary with magma composition, vesiculation and crystallization history. Furthermore, our results confirm that X-Ray microtomography is a powerful tool for investigating shape and internal structure of particles. It allows us to both characterize the particle shape by means of tridimensional shape parameters and relate them to their internal structures.
