Crushed Stone: The Unsung Mineral Hero - Geology

Dolomite (AKA "dolostone") and limestone are very similar rocks. Dolomite is a calcium magnesium carbonate (CaMg(CO 3) 2), while limestone is a calcium carbonate (CaCO 3). Limestone is more effective for making cement and for neutralizing acids. Dolomite has a Mohs hardness of 4 compared to limestone with a Mohs hardness of 3. This hardness difference makes dolomite distinctly more durable when the rock is subjected to abrasion.
