This means that dolomite marble tiles are more scratch-resistant as compared to calcite marble tiles. In addition, calcite tends to react more quickly with acids.
Quartzite vs Marble (Countertops Design Guide)
The reason for the big difference in their hardness is the minerals that each stone is composed of. Quartzite is entirely made up of quartz which is considered to be the hardest material on earth. Marble, on the other hand, is relatively soft because it is made up of calcite. Porosity and Moisture Resistance.

Calcite and Dolomite
Calcite and dolomite are very similar minerals. Both have the same hardness (H = 3), the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test: a drop of 1 M HCl on calcite produces an instant, obvious fizz; a drop on dolomite produces slow or no obvious bubbling.

On the other hand, dolomite marble tile reacts weakly, and produce carbon dioxide bubbles more slowly when an acidic solution is spilled on the surface. Consider dropping a 1 ml HCL on the surface of the marble sample. If the marble produces instant fizz or bubbling, it''s probably calcite marble tile.
