Physical properties of volcaniclastic sediments in the Izu-Bonin area

Abstract

With the possible exception of pumice-rich material, unlithified volcaniclastics behave much like detrital deep-sea sediments. In contrast, lithified volcaniclastic sediments display unique physical properties, such as higher electrical resistivity and velocity than expected from porosity values. The primary cause of these phenomena is a lack of interconnectedness of the pore spaces and cementation of the volcaniclastic particles. -from Authors
