The Density of Common Rocks and Minerals

2020-1-23  The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

Density of Rocks and Soils Chemistry LibreTexts

If the rock sample weighed 2.71 g and the soil 1.20 g, we could describe the density of the rock as 2.71 g cm –3 and that of the soil as 1.20 g cm –3. Even though sand is made of rock fragments, its density is less because the porosity of sand lowers its bulk density (as shown below). (Note that the negative exponent in the units cubic centimeters indicates a reciprocal.

Rock density and porosity PetroWiki

2015-6-25  For rocks without sensitive minerals such as smectites, the porosity and dry, grain, and saturated densities can be derived from the saturated mass, dry mass, and volume (or buoyant weight). These measurements allow calculation of saturated, dry, and grain density as well as porosity and mineral and pore volume by employing Eqs. 3 through 5 .

Understanding porosity and density

Density is defined as the mass per volume. In rocks, it is a function of the densities of the individual grains, the porosity, and the fluid filling the pores. There are three types of density in rocks: dry density, wet density, and grain density. The data table lists the dry, wet, and grain densities of the samples.

rock Definition, Characteristics, Classification, Types

Rock, in geology, naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. Rocks are commonly divided into three major classes according to the processes that resulted in their formation. These classes are (1) igneous rocks, which have solidified from

2007-6-28  Clays generally have density between 1.6 to 2.6 g/cc. The clay content of a soil has a significant effect on its density. Salt is of particular interest in sedimentary rocks because it has a low density (2.2 g/cc), but has a fairly high bulk modulus giving it a relatively high seismic velocity (velocity of acoustic signals within the rock).

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.
