Dolomite vs Limestone What's the Difference
Dolomitic Marble: Dolomitic marble is a metamorphic rock that forms from the recrystallization of limestone or dolomite under high heat and pressure. It is essentially limestone or dolomite that has undergone metamorphism, a process where the mineral composition and texture of the rock change due to geological forces.

Dolomite vs. Marble Countertops: Choose the Perfect Stone
Marble is formed naturally when Dolomite or Limestone recrystallizes under the influences of immense heat, pressure, and Calcium Carbonate-rich aqueous solutions, causing it to have a much finer crystal structure and a smoother look. Marble is known for being softer than Dolomite, which can make it more susceptible to damage over time.

Dolomite
Limestone that contains some dolomite is known as dolomitic limestone. Dolomite is very similar to the mineral calcite or traditional marble. Calcite is composed of calcium carbonate (CaCO 3), while dolomite is a calcium magnesium carbonate (CaMg(CO 3) 2). The best way to tell these minerals apart is to consider their hardness and acid reaction ...

Dolomite: Properties, characteristics and uses
The dolomite It is a common sedimentary rock-forming mineral and can be found in massive beds known as dolomites. Dolomite also forms as sediment in mineral veins such as limestone. Limestone where dolomite is present in more than a small amount is called dolomitic limestone. Dolomite is rarely found in higher temperature metamorphic settings.
