How Is Marble Formed From Limestone
marble
As marble the rock is more compact and crystalline. Some forms of marble metamorphosed from dolomite, a type of limestone composed of calcium magnesium carbonate. The formation of limestone and its metamorphosis into marble are part of a natural process called the rock cycle.
