Density varies significantly among distinctive rock styles as a consequence of dissimilarities in mineralogy and porosity. Expertise in the distribution of underground rock densities can aid in interpreting subsurface geologic construction and rock style. Metamorphism typically creates evident layering, or banding, because of the segregation of minerals into independent bands. https://rocksticks34566.daneblogger.com/35311548/the-5-second-trick-for-sticks-of-rock
