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 often forms as nodules in sedimentary rocks such as chalk and marine limestones. Dolomite (also known as dolostone and dolomite rock) is a chemical sedimentary rock that is very similar to limestone. It is thought to form when limestone or lime mud is modified by magnesium-rich ground water.The specimen shown above is about four inches (ten centimeters) across.t often forms as nodules in sedimentary rocks such as chalk and marine limestones.
