Selecting surface value

surface=rock + material=marble for roads and paths where raw rock is a surface

surface=paving_stones + paving_stones:material=marble for stone machined into a flat surface

note, images (except first two) have placeholder images not depicting marble specifically - but form would be the same

surface=sett + material=marble for flattened stone, but still not entirely flat and not covering entire surface

surface=unhewn_cobblestone + material=marble for true cobblestone of natural, uncut, rounded stones

surface=stepping_stones + material=marble for stones or plates individually arranged in a row, allowing to walk on, surrounded by an unpaved medium such as grass or water

surface=stepping_stones + material=marble for grass variant
