Correlations between ultrasonic pulse wave velocities and rock
The relationships between P-wave velocity and other rock properties have been investigated by various researchers. The transition time of the waves depends on the density of minerals forming the rocks (Birch, 1961).The relationship between the wave velocity and the density of rocks is usually considered to be linear (Youash, 1970).Relationships between …

Porosity measurement of granular rock samples by modified bulk density
Many authors have measured the porosity of crushed-rock samples in granular form with the density method, assuming (probably incorrectly) a constant bulk density for different granular samples by using the value obtained from a whole rock sample (Klaja et al., 2015; Sun et al., 2016; Fu et al., 2019; Gaus et al., 2020).

P-Wave Velocity Calculation (PVC) in Rock Mass Without
Ultrasonic studies have been used as low-cost, quickly updated, non-destructive techniques in geology and geo-technique. Conventional geophysical operations that allow measurements of wave velocity in rock mass are costly. In this study, we sought a strategy for calculation of wave velocity in rock mass without these field operations. The velocity of a wave …

To find the maximum and minimum values for the density of the rock, we start with the given value, which is 2.55 ± 0.10 g/cm³. This means that the density can vary by 0.10 g/cm³ from the central value of 2.55 g/cm³. Calculate the Maximum Density: Maximum density = 2.55 g/cm³ + 0.10 g/cm³ = 2.65 g/cm³

A detailed rock density model of the Hong Kong territories
The continental upper crustal density of 2670 kg·m −3 [5] is often adopted to represent the mean topographic density.This value was probably reported by Hayford [6] for the first time and has been used until now without a critical revision.A recent global study by Sheng et al. [7] indicates that this value could be overestimated.This is also supported by other studies.

Porosity and Bulk Density of Sedimentary Rocks
Average values for the porosity of sedimentary rocks have been given by Barrell (1914) as: shale, 8.2 percent; sandstone, 14.8 per cent; limestone, 5.3 percent; and all sedimentary rocks, 8.5 percent. Additional data since the publication of Barrell's summary indicate that the average value of 8.2 percent for the porosity of shale may be low.
