Density may differ significantly between different rock types due to variances in mineralogy and porosity. Understanding of the distribution of underground rock densities can assist in interpreting subsurface geologic composition and rock variety. Metamorphism generally generates obvious layering, or banding, due to segregation of minerals into independent bands.
