Most likely the marble will reflect more thermal energy.
Why: reflection of thermal (infrared) radiation depends on surface color/finish and material. Smooth, shiny, light-colored surfaces (like a glass or polished marble) have higher reflectivity (lower absorptivity/emissivity) so they send back more incident heat. Rough, dark, matte surfaces (soil/ground) absorb more and reflect less, so they heat up more.
Caveat: the exact effect depends on the specific materials and colors (a very light polished stone can reflect more than dark glass, etc.), and on wavelength (visible vs. thermal IR). But in the typical scene you described, the marble is the better reflector.
