Density varies substantially among the various rock forms as a result of differences in mineralogy and porosity. Understanding of the distribution of underground rock densities can help in interpreting subsurface geologic composition and rock style. Metamorphism often generates clear layering, or banding, due to the segregation of minerals into different https://griffinshvma.laowaiblog.com/35255662/facts-about-sticks-of-rock-revealed
