Dolomite minerals

Dolomite, or dolostone, is a carbonate sedimentary rock made mostly from the mineral dolomite, CaMg (CO3)2. It commonly occurs in association with limestone and shares many of the same properties, but reacts only weakly with acid. Dolomite often has a sugary texture and is typically off-white to gray in color.
