In metamorphic rocks, where strong foliations have developed, rock hardness is generally lower due to the preferred orientation of mineral grains and the structural weaknesses these impose. However, in low grade metamorphism where a foliation does not develop, but the rock became more indurated (i.e. more compacted and lower porosity), rock hardness increases.
