| contents | We examine the physical properties of volcaniclastic sediments in the forearc and backarc of the Izu-Bonin arc region. Based on our analyses of these and other deposits in the area, we conclude that, 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. |
