Dolomite minerals. Carbonate minerals, including calcite and dolomite, have moderate solubilities. Silicate minerals have relatively low solubilities. If water evaporates, it may become oversaturated in particular minerals and deposit chemical sediments, such as the salt deposits in the photo seen here (Figure 7.15).

Dolomite. The mineral dolomite is the main component of the sedimentary rock that is also called dolomite. It is similar to the mineral calcite but contains magnesium as well as calcium. Just based on looks, the rock dolomite is often impossible to distinguish from limestone, which is composed mainly of calcite. Dolomite crystals are usually ...

dolomitization, process by which limestone is altered into dolomite; when limestone comes into contact with magnesium-rich water, the mineral dolomite, calcium and magnesium carbonate, CaMg (CO 3) 2, replaces the calcite (calcium carbonate, CaCO 3) in the rock, volume for volume. Dolomitization involves recrystallization on a large scale.Mar 23, 2019 · Dolomite is an anhydrous carbonate mineral composed of nominally equal parts calcium and magnesium, with the formula CaMg (CO 3) 2. Its chemical formula can be more clearly written as CaCO 3 .MgCO 3. Because of the presence of two various cations, which form regular layers inside dolomite structure, dolomite crystal symmetry is lower than calcite. Many schists are medium-grade rocks. 8.10 Garnet granulite, a high-grade metamorphic rock.
