    The density and porosity values presented here are believed to represent the sampled rock types quite well, and the data provide some indication of the real varia­ bility of these properties for each rock type. This natural variability and the limited rock area exposed are the main difficulties in determining rock density distribution

  • The Density of Common Rocks and Minerals - ThoughtCo

    Jan 15, 2019· For example, the density of a one-inch cube of iron is much greater than the density of a one-inch cube of cotton. In most cases, denser objects are also heavier. 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.

    The same is true for rock weight in water and rock density; no correlation. Rock weight in air and weight in water are strongly correlated, however, since all common rock densities are similar, about 3 g/cc. The histogram shows that, although a wide range of densities are possible, common rocks …

  • Calculating Density

    Density is a fundamental concept in the sciences; you will see it throughout your studies. It is used quite often in identifying rocks and minerals since the density of substances rarely changes significantly. For example, gold will always have a density of 19.3 g/cm 3; if a mineral has a density …

  • How to Calculate Specific Gravity of Rock | Sciencing

    Apr 24, 2017· Specific gravity is a dimensionless unit that defines the ratio between the density of a rock and the density of water at, typically, 4 Celsius. Density is an important characteristic of a rock, since this parameter helps to identify the rock type and its geologic structure.
