Dolomite
| Dolomite looks very much like limestone except that it is
generally tan in colour and fizzes weakly if at all when a drop of cold dilute
hydrochloric acid is put on it. If dolomite is ground to a powder or hot acid is applied,
it will fizz strongly. Limestone and dolomite also weather differently: weathered dolomite
often becomes brown or reddish and rough and finely angular; limestone, on the other hand,
weathers smooth and light grey or white. |
