WebFeb 26, 2024 · Pumice, for example, has high porosity but low permeability. porosity. Porosity by definition is- 'the ratio, expressed as a percentage, of the volume of the pores or interstices of a substance, as a rock or rock stratum, to the total volume of the mass." WebThe efficiency of syn-eruptive magmatic vesiculation and gas escape influences the ability of a volcano to accumulate pressure and therefore influences the dynamics and style of eruption. We examine the pore structure preserved in pumice to learn more about the vesiculation and degassing behavior of silicic magma by combining laboratory …
