“…With increasing porosity, V p decreases gradually in a nonlinear fashion, confirming the observations of other researchers on loose sediments [11,12], but contradicting that on cemented sandstones, where an approximate linear correlation between porosity and V p is observed [13,14]. In low porosity cemented sandstones, the propagation of compressional waves is dominantly via the inter-connected solid sand frame, in which case, a small increase in porosity will dramatically decrease the bulk and shear moduli of the rock resulting in a rapid reduction of the wave velocities.…”

“…Physical properties of marine sediments are important variables in order to understand geological events in marine environments and they play an important role in determining the nature of fluid and gas migration, which in turn affects the nature of microbial communities and gas hydrate formation. Several studies have been conducted to examine the relationship between physical and textural parameters of marine sediments (Orsi and Dunn, 1991;Weber et al, 1997;Kim et al, 2001;Casas et al, 2004). The physical properties of sediment depend to a large extent on lithology, grain size and the proportion of the different components of the sediment (e.g.…”
