Dolomite ranks higher than marble on the durability scale, largely due to its dense mineral composition. Slightly hHarder than most marbles, dolomites tend to resist scratches and heat more readily. However, this stone is not quite on par with the density & durability of granite and quartzite. In other words, it's a good middle-of-the-road ...

Depending on the content of quartz, dolomite, and other minerals, the density of limestone ranges from 2700 kg/m3 to 2900 kg/m3. For information on the strength of nummulite limestone in compression, a test was conducted according to GOST 30629-2011. Five samples-cubes with the size of edges 5 cm were made from the core.

Marble is a metamorphic stone formed when limestone is subjected to intense heat, pressure and chemical solutions, causing the stone to reform into an interlocking structure of calcite, aragonite, and sometimes dolomite crystals. Marble formed from very pure limestone is white, but the presence of other minerals, as well as clay, silt

Oxidation of sulphide mining waste can generate acid mine drainage (AMD) that has the potential to seriously affect the ecosystems. Acid mine drainage is characterised by a high acidity, high concentrations of sulphates and metals.

Marble tends to be more expensive than dolomite. Dolomite can cost from $60-$80 per square foot. Marbles can range from $75-$200 per squar foot just for the material. However, the exact costs can vary based on the color, pattern, and origin of the stone. I always recommend researching the prices in your area.
