PROPERTIES OF ROCKS AND THEIR APPLICATIONS ROCK

4.3 Rocks and Their Properties Formation of Rocks: The Earth‟s crust called „Rock‟ is built up of different mineral aggregates. Rocks may be mono-mineral e.g. marble or poly-mineral e.g. granite. The mineral composition of a rock is almost similar but its chemical composition depends on kinds of constituent minerals.
