Their results and/or metamorphism can bring about a chemical alteration to the arrival of recent minerals. Even trendy deformation of real fabrics, foliations, or even cleavage planes of the mineral, inflicting it to weaken and separate in crumbles from its determined rock.

It can occur even in case your rock seems ideal on its surface. This is due to the fact crystals can be fractured and if this occurs at first-rate depth, they may be “rehealed.”
