  • Dolomite (rock) - Wikipedia

    Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 65 million years in age).

  • Dolomite: A sedimentary rock known as dolostone or ...

    Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar rocks.

  • Limestone - Wikipedia

    Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Dolomite, CaMg(CO 3) 2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium.Calcite in limestone is divided into low-magnesium and high-magnesium ...

    Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.

  • Limestone: Rock Uses, Formation, Composition, Pictures

    Dolomitic limestone is a rock composed mainly of calcite, but some of that calcite has been altered to dolomite. Dolomite is thought to form when the calcite (CaCO 3) in carbonate sediments or in limestone is modified by magnesium-rich groundwater.

  • What happens when acid reacts with limestone? |

    Jun 15, 2008 · Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will

    While some carbonate rocks form as simple chemical precipitates most carbonate rocks are the product of marine organisms such as molluscs and corals. They precipitate calcite (calcium carbonate, CaCO3) or other similar carbonate minerals directly from the dissolved chemicals in the water to create their shells. Limestone is the product
