This study has been undertaken to investigate the determinant sedimentary rock that is made up of marine deposited calcium and magnesium. It may contain tiny fossilized remains of plants and animals. It has a pearly luster, is soft enough to scratch with a knife, and reacts very slowly with acid. It is used in road and bridge construction, buildings and as a dimension stone. Good quality Dolomite is a source for magnesium used as anti-acids Processes of dedolomitisation are related to dolomite and dolomitic limestone aggregates.The mechanismand reactions of dedolomitisation are known and widely describe.Dolomite and limestone are very similar rocks. They share the same color ranges of white-to-gray and white-to-light brown (although other colors such as red, green and black are possible). They are approximately the same hardness and they are both soluble in dilute hydrochloric acid. They are both crushed and cut for use as construction materials and used for their ability to neutralize acids. Dolomite is very common in the rock record but the mineral dolomite is rarely observed forming in sedimentary environments. For this reason it is believed that most dolomites form when lime muds or lime stones are modified by post depositional chemical change.Dolomite originates in the same sedimentary environments as limestone - warm, shallow, marine environments where calcium carbonate mud accumulates in the form of shell debris, fecal material, coral fragments and carbonate precipitates. Dolomite is thought to form when the calcite (CaCO3) in carbonate mud or limestone is modified by magnesium-rich groundwater. The available magnesium facilitates the conversion of calcite intodolomite (CaMg(CO3)2).
