The action of the table creates inverse classification and stratification, i.e. each mineral of a certain specific gravity is arranged according to size. (See fig. 13)

The Density of Common Rocks and Minerals

Mineral and rock densities 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 .

MINERAL PROPERTIES: SPECIFIC GRAVITY

The specific gravity of a mineral determines how heavy it is by its relative weight to water. The specific gravity value is expressed upon how much greater the weight of the mineral is to an equal amount of water. Water has a specific gravity of 1.0. If a mineral has a specific gravity of 2.7, it is 2.7 times heavier than water.
