Description
Recrystallized dolomitic limestone producing interlocking grains of dolomite.
Marble, both limestone and dolomitic, is an extremely variable rock in appearance since it depends on what rock was the parent, and the degree of metamorphism it underwent. It can be virtually any color from white to black to red to green, etc., and sometimes it will contain metamorphosed fossils or other components. The most definitive test for the rock would be acid (weak bubbling or bubbling only when powdered), and a hardness less than glass.
