Limestone Rock Uses Formation Composition Pictures

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. The available magnesium facilitates the conversion of calcite into dolomite (CaMg(CO 3) 2). This ...

May 18, 2018 Dolomitic marble can be converted to calcite marble by dedolomitization, that is, the leaching out of magnesium. Dolomites are used as magnesium ores, as a source of pharmaceutical magnesia (MgO), and as a flux aid to the removal of impurities in metal refining.

Dec 07, 2011 The calcitic marble would also be more reactive than dolomitic rock for the same particle size. Hence, particle size of the carbonate rock was a critical parameter for the design of an ALD since it governs water flow (or the hydraulic retention time) and neutralisation capacity of the system.

Dolomite is a sedimentary rock, a close cousin to limestone. If limestone turns into a metamorphic rock, it becomes marble. If dolomite turns into a metamorphic rock, it becomes dolomitic marble. Saying dolomite isnt marble doesnt really make sense, but thats ok. One neednt be a geologist to understand basic stone properties.
