Marble is what kind of metamorphic rock. Marble is a metamorphic rock. Metamorphic rocks form when rocks are subjected to high heat high pressure hot mineral rich fluids or more commonly some combination of these factors. Any unique combination of chemical composition mineralogy grain size texture or other distinguishing characteristics can describe a rock type. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock.

A metamorphic rock on the other hand began as a rock either a sedimentary igneous or even a different sort of metamorphic rock. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. The following is a list of rock types recognized by geologists.
