Dolomite | Formation, Structure, Properties, Uses, & Facts
The dolomite of most dolostones is granular, with the individual grains ranging in size from microscopic up to a few millimetres across. Most dolomite marbles are coarsely granular with individual grains ranging between 2 and 6 millimetres (0.079 and 0.24 inch) in greatest dimension. Vein dolomite grains may be up to several centimetres across.
