Dolomites are chemical sedimentary rocks that almost resemble calcite. The similarity is because dolomite at first begins to take shape as limestone but they are later chemically altered through the substitution of some of its calcium by magnesium. Chert; Cherts are chemical sedimentary rocks formed due to the deposition of cryptocrystalline quartz.

Dec 11, 2019· Dolomite (also known as dolostone, dolomite rock or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2. In old USGS publications, it was referred to as magnesian limestone, a term now reserved for magnesium deficient dolomites or magnesiumrich limestones.

Dolomite, which is named for the French mineralogist Deodat de Dolomieu, is a common sedimentary rockforming mineral that can be found in massive beds several hundred feet thick. They are found all over the world and are quite common in sedimentary rock sequences. These rocks are called appropriately enough dolomite or dolomitic limestone.

Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous finegrained texture. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks.

Dec 03, 2013· Dolomite. Dolomite is also a carbonate mineral but is made of 'calcium magnesium carbonate' instead of pure calcium carbonate material. Therefore, dolomite is called a double carbonate rock, and it doesn't readily dissolve in dilute acidic media. The way dolomite is formed is not quite clear, and it has been found that it forms under high saline conditions in environments like lagoons.

Dolomite is a sedimentary rock composed primarily of calcium magnesium carbonate. The word dolomite is also referred to dolomite mineral so sometimes being confused between rock and mineral. Limestone is composed of calcium carbonate and dolomite is composed of calcium magnesium carbonate so it is thought to be originated by the post depositional alteration of limestone via .
