A lot of the time, people are so desperate to get rid of acne scars and skin discolorations that they will use all manner of abrasive products and methods which can irritate the skin and make the situation worse.
Chemically, the distinction between limestone and dolostone is that the first one is chiefly composed of calcite, CaCO3, whereas the second is rich in MgCO3-Dolomite-. Therefo â¦ re, the difference is limestone has Ca and Dolostone has Mg.   Mg is replacing Ca in the dolostone, in other words.   It is very difficult to make the distinction in a macro-scale samples. You will need optical or chemical procedures to differentiate each one.
It is a calcium magnesium carbonate with a chemical composition of CaMg(CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.ontributor: Hobart King. Dolomite: A Mineral and a Rock.
