core samples (hyaloclastite and basalt) saturated with low-saline water. Such an analysis which predicts how the rock bulk modulus (accordingly 41 the seismic velocity) changes with a change of pore fluids is well known as a fluid substitution analysis (Gurevich et al., 2007, and references therein). Central to the fluid substitution problem are

Elastic Laboratory Measurements and Modeling of Saturated ...

However, when samples are water saturated, the bulk modulus of the rock is frequency dependent. Modeling with Gassmann's equations predicts the measured saturated rock bulk modulus for all fluids for frequencies below 20 Hz but underpredicts the water-saturated basalt bulk modulus for frequencies greater than 20 Hz.

P-wave modulus - Wikipedia

In linear elasticity, the P-wave modulus, also known as the longitudinal modulus or the constrained modulus, is one of the elastic moduli available to describe isotropic homogeneous materials.. It is defined as the ratio of axial stress to axial strain in a uniaxial strain state (i.e. where the oscillation height is negligible in comparison to the cross-sectional area)

The term rock refers to the bulk volume of the material, including the grains or crystals as well as the contained void space. The volumetric portion of bulk rock that is not occupied by grains, crystals, or natural cementing material is termed porosity.

The basalt fibers typically have a filament diameter of between 10 and 20 µm which is far enough above the respiratory limit of 5 µm to make basalt fiber a suitable replacement for asbestos. They also have a high elastic modulus, resulting in high specific strength—three times that of steel.
