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.
Dolomite has a calcium layer, then a carbonate layer, then a magnesium layer then a carbonate layer, and so on. Dolomite is harder and denser than the calcite form of calcium carbonate or limestone, and is more chemically inert and more impervious to acid attack.olomite is believed to have formed by replacement of some of the calcium in a calcium carbonate limestone deposit with magnesium, while the sediment was undergoing lithification, being converted from layers of dead clam and other sea animal shells into crystallized calcite or calcium carbonate.
