3.7 Metamorphic Rocks
Mineral banding in the high-grade metamorphic rock gneiss. This segregation of minerals together is a type of foliation. The second requirement needed for a foliated texture is directed pressure called differential stress. If pressure is applied unevenly, the weak minerals in the original rock will easily deform into long planes.

Limestone: Uses, Benefits, and Side Effects
Limestone is chemically called calcium carbonate and is thus, abundantly rich in calcium. Besides this, a host of other minerals are present in it, making it suitable for good health. The practice of eating limestone with betel leaves (paan) is common in India. The major health benefits associated with limestone have been discussed below.

The minerals calcite and dolomite are the main ingredients of limestone. Both are calcium-bearing carbonate minerals, meaning that they contain the chemical elements calcium (symbol Ca), carbon (symbol C) and oxygen (symbol O). Each carbon atom is combined with three oxygen atoms to form what is called carbonate (formula CO 3).
