Limestone is common a rock that makes up about ten percent of all sedimentary rocks. Limestone is made up of calcite aragonite. A lot of limestone comes from skeletal fragments of marine organisms. Throughout history, many people have recognized limestone's potential and used it for a building material.

If quartz is present, the metamorphic reactions in marbles are often decarbonation reactions that involve the breakdown of carbonates to release CO 2.If a pluton intrudes a limestone or dolostone, contact metamorphism may cause CO 2 to flow out of the carbonate and combine with H 2 O that comes from the pluton. The CO 2-H 2 …

Although feldspar is a fairly hard mineral, it does cleave (split apart) and is chemically reactive, especially in the presence of water. The most abundant product of chemical reaction of feldspar and water is clay minerals. During the erosion-to-deposition process, clastic sediments lose feldspar and gain a larger proportion of clay.
