[http://www.geologyrocks.co.uk/tutorials/introduction_to_carbonates Carbonates] are sedimentary rocks composed primarily of carbonate minerals, including calcite (CaCO<sub>3</sub>), aragonite (CaCO<sub>3</sub>), and dolomite (CaMg(CO<sub>3</sub>)<sub>2</sub>). The proportion of each mineral in a carbonate rock can be determined by [[SEM, XRD, CL, and XF methods|X-Ray Diffractometry]]. Carbonates more rich in calcite and/or aragonite are called limestone. Carbonate rocks composed mainly of the mineral dolomite are also called dolomite (formerly dolostone). When metamorphosed both rocks become marble.
