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.
Itâs important to keep in mind that, as stated above, dolomitic lime is really intended only for soil that has a magnesium deficiency. As a general rule of thumb, soil should always have a calcium to magnesium ratio of between 7:1 (for sandier soils) and 10:1 (for more clay-based soils).
