Density
Rocks are generally between 1600 kg/m 3 (sediments) and 3500 kg/m 3 (gabbro). Tables of geologic material densities are given in most text books, but the simplicity of a table hides the wide range of values most real materials can …

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.

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).
